Last year's Q&A's

i do like zebra plecos. They are very hard to get. can you give me a list of Tropical Fish Stores who sells these pretty Plecos?

Hi, can you suggest so fish for me? I hve a 10 gallon tank, & have 2 clearglass fish, 1 golden aglea eater, & 1 albino cory catfish. I don't want any Mollies, or any Tetras, not in this tank anyway. Pleas help me out thank you.

Houston, Tx USA - Sun, January 20, 2002

The real trick here is to find something that the golden algae eater won't bother. You have the bottom of the tank covered with the cory. How about a hatchet fish? This fish is unusual in shape, silvery in color and hangs out at the top of the water. Another possibility is white clouds which are not tetras but small chinese minnows. If you get white clouds, be sure to get at least three as they are schooling fish and unhappy and shy by themselves.

I have a 20 gallon tank with about 8 platties that have nearly destroyed my live plants (hygro and wisteria). Are there any types of common plants (i.e. easy to find at most pet stores) that will survive? I was wondering if broad leaved plants might fair better. I really prefer live plants over plastic ones.

Try some amazon sword plants and feeding your platies some boiled lettuce. <>>><

My boyfriend bought a bristle nose pleco a few days ago. the first two days, the fish seemed fine, looking healthily plump, and almost cleaning all the algae off the back of the 55 gallon tank. then while we were watching it on the third day, all of a sudden it violently jerked its body forward, and died. we noticed that her body had turned very red under the skin, as if she had hemorhaged. no signs of cuts or sores or any other problem. what could have caused this?
USA - Mon, January 28, 2002

It sounds like Enteric Septicemia. A bacterial disease of catfish. Bacteria is ingested. Very high mortality and in some cases, very few symptoms. Be sure to disinfect the tank before introducing any other catfish! <>>><

hi~ over xmas holidays ,walmart had a bubblegum fishtank,and dumb me didnt buy one. Now they do not have these in stock. I have came across a bubble gum machine.. and before i buy this ,i want to know how i can turn this into a fishtank? Is this possible? Thanks jessica
jessicam21 <>
mcewen, tn USA - Wed, January 30, 2002

I wouldn't recommend trying to covert a bubble gum machine. 1. There may be unknown toxins in the paint or metals, 2. The complications of filtration and cleaning. Perhaps, you can find a novelty/unusual fish tank store on the web. <>>><

I have a 10 gallon tank. I am new to this whole fish tank thing. We have had the tank set up for about 4 monthes and now the Ph seems to be dropping. I have read not to do anything about until it gets really bad. however, our tank got so acidic that we had to put Ph increaser in it. Now all of our fish are dying i have no idea how to get the tank back to a good Ph. Help.
Denver, CO USA - Thu, January 31, 2002

You need to be careful when changing water chemistry. Consider changing 1/4 of the water in the tank for the next few days. Hopefully, that will settle out the tank. Be sure to use declorinator and water that is within 5 degrees of the same temperature that is in the tank already. Good tank maintenance requires water changes between 10 to 20% of the total tank water on a regular basis. Small tanks require more frequent water changes--once a week or every two weeks, rather than once a month.

Hi On Sat., Jan. 26 I bought some was pregnant and had fry Sun. many days,weeks, months,etc. will I have to wait to put them in the tank with the other fish? I have a ten gal. tank w/out lot of plants and I have a silver molly (m), black molly (f),orange? molly (the proud mom)mickey mouse molly(f)and a marble molly(m). I have the fry in a small fishbowl right now and I know they will outgrow that soon....they are less than 1/4 in. long and can hide(and get stuck) under the large gravel...HELP!! Also, the mom looks that normal? I AM treating them for ick, but all the other fish seem fine. Thanks for your help.
co USA - Thu, January 31, 2002

Your fry will need at least a month to grow. You can move them into a bucket when they get bigger. Mom Mollie certainly should be sluggish after that ordeal :)

Hi Me does ick medicine affect fry?
co USA - Thu, January 31, 2002

I wouldn't advise treating fry for ick. If you insist on treating them, add a little bit of non-iodized salt. Mollies do well with a little salt in their water. (1 tsp for gallon).

Hi Me AGAIN :) My friend said not to put any fish in the same tank with goldfish because their "toxic waste" will kill this true?
co USA - Thu, January 31, 2002

Goldfish do create a lot of waste and shouldn't be mixed with tropical fish. Goldfish are actually a cold water fish and thrive under cooler temperatures. You have to be sure to keep the tank clean if you're going to mix fish.

Do minature Catfish eats smaller aquarium fish?

Clover, SC USA - Thu, January 31, 2002

Plecos and other catfish have been known to prey on smaller fish,especially at night when some fish sleep on the bottom of the tank.

Hi I saw my mollies breed today, and I have a few questions....What is the gestation period for mollies? When should I put the pregnant mom in a net? The last time my mollies had fry...I wasn't expecting them so soon and had to catch them in a net.....needless to say, they hid under the rocks, got stuck, and some I have 19 istead of 25 or 30. I don't want to lose any this time...I'm hoping to sell them to a pet shop. How many fry do mollies usually have? If left with the fry, but well-fed,will the mom eat them? I know the other fish will, but I don't know about the mom. Also, is it normal for a mom to die after having fry? I read the post about bettas, but I don't think that applies to livebearers. :)Thank you so much for your help!
co USA - Fri, February 1, 2002

Whew -- It's difficult to say, when mollies are going to produce young, because they can give birth months and months after the initial fertilization. I wouldn't have high hopes about selling the young to a pet shop. Mollies breed easily and I'm sure most pet shops have plenty of breeding pairs. Just enjoy the challenge of raising the fry. Mom mollies generally don't eat their young, watch out for Dad though! <>>><

We just got a 10 gal tank, 6 goldfish and 1 plecostomas (my son calls a "sucky fish" and was his idea). Anyway, do I have to give the pleco special food or would he get enough from the waste of the six goldfish? I don't have any live plants in the tank. Like many others, we're new to all this and just don't want to mess up! Thanks a lot!!!
Eupora, MS USA - Fri, February 1, 2002

If you're feeding the goldfish the special food that comes in little hard pellets, you may want to pick up a can of the flake food for the pleco. If you're feeding the goldfish flake food, there is no problem at all. Just be sure to stir some of the food into the tank so it drifts to the bottom. Give enough food for the fish to feed for three minutes twice a day. Goldfish eat a lot. Happy fishing <>>>><

I have recently set up a 55 gallon tank, with fake plants and log. The only temperature that i can get it to stay at is around 70-74 with a PH of 7.2, I have tried to get it to where i can put tropical fish in it but failed. I would like decently big fish (for the size of the tank that is), i have put in a dozen feeder fish (due to the temp and ph level) to build up the atmosphere. What type of fish would you suggest?
Adam <>
Salem, VA USA - Sat, February 2, 2002

Gouramis, Bala Sharks, Red tail sharks, loaches are all reasonably hardy fish that will do well in a 55 gallon. If you like Cichlids, they also will do well in a 55 gallon. Most folks would love to have your problem. I have a 40 gallon and 35 gallon tank myself. <>>>><

Hi there - I have a male Beta that we have only had for a week. Today we noticed he appears to have fin rot. I went to the fish store today and they recommended Melafix. I've started treating him right away. This has me a little worried though - maybe Betas aren't as tough as I've heard they are... Is there anything else I can do to take care of him? We have him in a 5 gallon tank, with a filter, and keep the water at 80 degrees. How often should we change the water and how much at a time? Do we need a PH kit? Are there any other things that we should be checking for? We really want to take good care of him.
Terry <>
Halifax, NS Canada - Sun, February 3, 2002

It sounds like you're giving your beta good care. If you like, you can get him some tiny live food and add a little bit of salt to his water. You don't really need a PH kit, you'll change 1/4 of the water every couple of weeks and that will be fine. Most betas do not get as good a home as you are giving yours. Hope he get's better.

We have had a pleco for about 10 years and he/she was about 5 when a friend gave him/her to us, so Pleco is about 15. I was curious about their lifespan as well (read the post you answered 15 to 20 years), as this fish has outlived so many other fish over the years. I was going to dismantle the tank after all the fish were gone (i.e just not replacing as they aged and died), but when it got down to just the pleco and one bloodfin tetra, I restocked with a bunch of neons and am enjoying the tank all over again. Pleco is really looking ancient, but still pretty lively, considering. Neons are really cool. I just got 4 black neons and 4 blue and red ones. What other colors do they come in?
Carole Green <>
Jacksonville, FL USA - Sun, February 3, 2002

Glad you're enjoying the hobby and have such a happy Pleco. Neons basically come in the colors you described. Perhaps the breeders have created something new and radioactive in the past few years :) I remember when they injected glass fish with colors of the rainbow. Neons/cardinals are very pretty because of the iridescence in their coloration. Add the fact that they school and your tank becomes a fairyland. <>>><

hi, i am sorta new to all this fish stuff, and would like to know why the water gets cloudy. i don't have small children who would like to stick their hands in the water and i certainly don't put mine in either. i have a male betta, four different mollies, one albino catfish and one of those really ugly algea eater/catfish. i do have a filtration system and live plants in a 10gal. tank. i forgot to mention that one of the mollies had babies and they are getting quite big. please help before i lose any of them. thank you.
annada, mo USA - Thu, February 7, 2002

New Tank Syndrome -- that's what the fish hobbyists like to call cloudy water. Sometimes if you leave it alone, it will clear up all on its own. Let the tank rest for a day or two. Stop feeding the fish. They'll survive just fine without food for a couple of days and give the tank's biofilter a chance to catch up. Once the biofilter kicks in, the water will start to clear up. If you're impatient, you can buy drops from the pet store that claim to clear up cloudy water. <>>>><

hi, im kind of new in this fish hobby so i need help with my 29 gal.tank i have the tank set up for 3 month now and my ph was at 7.0 always now all of the sudden my ph is at 6.4 am i doing something wrong? i change about 20% of the water every week am i changing the water too much? and i have a 300 and a 150 aquaclear with 14 fish in it my bigger fish is about 3.5 inches then the rest are 1.5 to 2.5 inches. can you please help me. thank you
newark, nj USA - Fri, February 8, 2002

20% of a 29 gallon tank is overdoing it a bit. I'd change your water twice a month rather than every week. Do you have any live plants? Plants would help equalize your PH. Do your fish look stressed? Small changes in PH usually don't harm the fish. <>>><

How can you tell if your molly is pregnant? Also, it is hanging round the bottom. Is this a bad thing or is it a part of pregnancy? Please reply, Peter Mathews.

Mollies will have a dark spot under their abdomen when they are pregnant. Many mollies come pregnant out of the supplier. When particularly gravid, the molly may get listless. <>>><

Getting ready to stock a 55 gallon tank with Orandas. What kind of algae eating fish do you recommend putting in the tank. Thinking about some otocinclus fish. Is that doable?

We have a 35gallon tank in our home with the clear catfish, Kryptopterus bicirrhis. One catfish is now getting rounder around the belly? Could this fish be pregnant? Their are also two other clear catfishes in the tank as well.

I am a beginner. I have a 10 Gallon tank and all of a sudden my fish started rubbing against the decorations, I treated them for velvet dust disease and after 4 days of treatment two of my tiger barbs died and then my albino cory cat died. now my red-eyed tetras are acting funny. they are swimming in circles against the glass and chasing each other. Will i have to dismantle the tank and clean it to get the sickness out of the tank? HELP!!!
Jenn <>
NY, NY USA - Tue, February 19, 2002

It would be best to dismantle your tank. Change the gravel and plants. Treat fish separately in a sick tank. <>>><

I have 3 red-eyed tetras. I need to know what kind of other fish are compatible with these. they only seem to chase each other. i had 3 tiger barbs but all died due to velvet dust disease. I also need to know what kind of pleco would stay small enough to be in a 10-15 gallon tank for awhile. I like the clown pleco but can't seem to find anyone carrying that kind. also told by one reference that they don't grow bigger than 6". but other reference says 12". Who is right?
Jenn <>
NY, NY USA - Tue, February 19, 2002

Most plecos get large, I would suggest staying with smaller cats like corydoras since you only have a 10 gallon tank. <>>><

I just wanted to say, your page is helpful, however there is some incorrect info, or things not being addressed. ONE Goldfish requires 10-15 gallons at least because of waste and potential size. Also, you see to be encouraging people to overstock their tanks. One poster had 2 plecos and other fish in a 10 gallon. While getting more fish may be ok in her case based on water parameters, it should have been mentioned that she should expect to upgrade to a larger tank in the future.
NY USA - Tue, February 19, 2002
Beginning hobbyists often overstuff their tanks, that is true. That's why I recommend the 1/3 water change every couple of weeks to help alleviate the build up of toxins. If the tank is underpopulated, water changes need not be so frequent.
As the fish get larger, most folks take the hint and get a bigger tank <>>><

I want to breed my jewled cichlids but i cant tell witch one is a male and female can you help me please

Usually the male will brighten in coloration when it comes into mating season. Females tend to have heavier bodies.

because of your help, all of my <expletive deleted> fish died
???, ??? ??? - Mon, February 25, 2002
The care of fish is not an exact science and sometimes the fish are already stressed out to the point of no return.
All I can say is that I am sorry. Be sure to clean the tank thoroughly with new gravel and plants before starting over.

Thanking you in advance...I know I have compatable fish and the right plants and toys (if you will) right temp, etc. However in one of my tanks the water insists on becoming "cloudy"'s actually kind of strange because it starts becoming "cloudy" on the very bottom first (like a fog) and the drifts up...the fish don't seem to be "stressed" but I am...tried everything...any suggestions or!

I have a platy that had babies.... i added and algae eater, another platy (orange and black) and a dalmation fish. All of my baby orange platy's have disappeared and now there are little black ones.

I have a zebra fish and it is fatter than the rest of the zebra fish. How can you tell if there a boy or girl? Also, how can you tell if its pregnant?
Peter Mathews <>
Perth, WA Australia - Fri, March 1, 2002

The female is generally fuller-bodied and larger with subdued colors. On the males one can find a golden-yellow background with fine red lines between the weider blue longitudinal lines. On the female, the background is silvery white. Breeding takes place in shallow water no more than six inches deep with lots of plants and some sunlight. Place the female in the tank one day before spawning and add the male the same evening. The pair will normally spawn in the early hours of the morning and the eggs will be deposited on the plants. Good luck. <>>><

I have a 20gal tank I'm having a problem getting the water clear and I just got the nitrite levels down from 5.0 to .50ppm by changing about 6gals water. but now the water is cloudy, but the fish appear fine, I do water changes once a week about two gals each time. I have 14 fish(5 med. Tiger Barbs 1.5 to 2.0 inches,5 Black Ruby Barbs .25 to .75 inches, 2 Bala Sharks 2.0 inches, 2 Plecos 1 is about 3inches and my tiger pleco is 1.5inches, i also have a red claw crab), 1 Java Fern, & some driftwood and using a a hang-on power filter that filters 150gals an hour,the PH is 7.0, Gh & Kh is good, temp. is steady at 80 degrees, I'm going to be buy a 55gal tank this weekend and I do not want the same problems in the new tank what am I doing wrong and what I do I to fix the problem? I've tried water clarifier BY PROQUATICS and it does nothing.
Plainsboro , NJ USA - Sat, March 2, 2002

I'd increase the water change to 15% to 20% of the size of the tank.
For a 55 gallon tank, make the water change about 8 gallons. <>>><

I have a gourami that I can't tell what kind it is. I thought it was a blue gourami but on the tank we bought it from it said leopard gourami. Is there such a fish? Also, I purchased a extremely small pleco. It doesn't look like the typical pleco, it is dark gray like on top and has a black line down his side and white belly and white dots on the top and bottom of the tail fin. Can you suggest a website or book that I can look at to identify these fish?

I put algae disc pieces in my 10 gallon tank for my pleco and it seems like my pleco never gets to eat them. My gourami seems to sit and eat it until it is gone. Is this normal? My gourami seems to swim constantly back and forth across the tank until I feed it. Also, the gourami is really thick in the front of his body, could it be female and pregnant? How can I tell what sex it is?
Jenn <>
NY, NY USA - Mon, March 4, 2002

Boil some lettuce for your gourami and pleco, obviously, the gourami is hungry for some greens. Females are generally bigger than the males, they spawn under certain conditions times rather than "get pregnant". <>>><

I have a 20 gallon aquarium that was purchased around Christmas. We have had the water quality checked at the pet store before adding fish. My problem is that I have purchased two plecostomas - both died. Now the tank is growing lots of algae. I would like to purchase another, but not if it is also going to die shortly. Any suggestions?
Darien, IL USA - Wed, March 6, 2002
Plecostomas as generally hardy fish. Try a different supplier. <>>><

rochester, Washington USA - Sun, March 10, 2002
It depends on the number of fish you have and whether you like clear water versus a sort of yellowish colored water. It's definitely healthier to clean the fish tank and change the water once in a while <>>><

hi i have a problem with my tank i was looking in my gravel today and i seen little worms in my gravel could you tell me how to get rid of them and what causes them id appreciate it alot. thanks
cheryl <>
clairton, pa USA - Sun, March 10, 2002

The little worms are probably harmless, they probably hitched a ride on your fish into your tank. I wouldn't worry about trying to get rid of them as long as your fish are healthy. <>>><

Can beta fish have light in their aquarium? and do they like it?
ashlee <>
lindal, tx USA - Sun, March 10, 2002

Yes, you can have a light with a beta. It would be nice if there are some decorations that give shade (a hollow rock, a plant with broad leaves) so the beta can get away from the light once in a while. <>>><

I have recently moved and when I set up my freshwater tank it began growing algae. Could it be the new flourescent light (my old one burned out), or the well water that I now have?

Hi. I just upgraded to a nice 55 gallon aquarium. I have a male and femal molly, five platies, two female guppies, 7 neon tetra, and two small catfish so far. My female molly had about 25-30 babies the day after I bought her! A platy had 2 babies. All but five of the mollies died being sucked up by the regular filter(not undergravel) but mostly for some reason when I put them in a plastic floating breeder type container. Why did the breeder kill 11 fish? I am scared of getting a plague of unwanted fry as well (a few growing up would be nice) This is why my two guppes are femal. Any suggestions?
The Luckster
Sterling Hgts., MI USA - Wed, March 13, 2002

Instead of putting the fish into a plastic floating breeder container. Cut a piece of nylon pantyhose type legging and cover the filter intake with that. It will keep the young from being sucked up immediately. Some fry will die under natural conditions, that's one reason why the mollies, platies, etc. have so many at one time. <>>><

i have several fish tanks a 55 and 25 and several 10's.i wanted to change my 25 to salt water and need to know how to do it and what i need to buy.any sugestions would be great thanks.
Samantha <>
douglasville, ga USA - Wed, March 13, 2002

First you need to change the substrate to a coral/calcium gravel. Add a strong filter and sea salt mix. Run the tank for about a week then add a small fish under one inch in length for a month to get the biological cycle started. Gradually, add other denizens but keep it to down to 5 inches of fish. If you want invertebrates like sea anemones you'll need to get a special coral sea light fixture. Change 15% of the water twice a month. <>>><

my tank water turns neon green after two or three days. what to do to stop the greeness?
ny, ny USA - Thu, March 14, 2002
If your tank is near a window, move it further away from the light. If it's turning green under regular light conditions, I'd try some over-the-counter algae killer. <>>><

I live in a rural area where we have water from a well. I just got a new fish tank and set it up (no fish yet) and tested the PH. It was off the chart alkaline wise. I tried adding PH down stuff to it but have so far put in about 5x the recommended amount and it is still off the chart, way above 7.8. On a lark I tested my bottled spring water and it was a perfect 7.0. Is this safe to use instead of putting tons of chemicals in the tap water? Does it lack anything else that fish may require? Is it safe to assume that bottled water is neither to hard or to soft? Also I was going to get a couple of neon tetras and am looking for some other colorful smaller fish that would all play well together any suggestions? I am not interested in breeding or anything like that, I just want them to be pretty to look at. I'm also looking for a catfish that would remain on the smaller side hopefully with some interesting markings vs. just the silvery color. Any help would be appreciated.
Melrose, NY USA - Fri, March 15, 2002

Bottled water of ph 7 would be perfect for your neon tetras. There are some nice catfish that come have pretty patterns of stripes or dots that would be fine companions. <>>><

i have had a fish tank with golden gourami for about sixs months all has been well until now, one of the fish will not feed and has become very pale in colour it is resonably active at times do you have any advise? Thanks Nigel
nigel <>
london, uk - Sun, March 17, 2002

About 90 percent of all fish-related problems are due to contaminated or insufficient water from filter, food dosages, having too many fish in one aquarium or moving location. None of these seem to be implied in your case. You may want to remove the pale fish from the others in case the fish has something contagious. Put the fish in a large container of water (preferably a two gallon bucket) in a warm space and add a small amount of salt to the water (1 tsp to the gallon). If you have a spare air tube and pump put it in the container also. Otherwise, change a cup of the water per day. Do not feed it the first day, try a little food on day two. When the fish looks better, you can put it back in the tank with the others. <>>><

My children's goldfish have ick. I put the "Quick Cure" drops in and within a few hours the fish were all bottom dwellers. I did a partial water change but I'm afraid to put the drops in again. I took out my carbon filter, because the Wal-mart clerk told my husband I was supposed to, and stuck in a filter with no carbon. They, the fish, seem to be doing better since the water change but I need to know if it is okay to put in drops. The water temp is 66 degrees and I don't know how to raise it unless I purchase a heater and I really don't want to if I don't have to. Any advise??
State College, PA USA - Sun, March 17, 2002

If you have a heating pad, you could place that near the tank to raise the temperature a little -- say to about 70 degrees. Another way to heat your tank would be to put an incandescent lamp near it (standard light bulb). Continue to do partial water changes (1/4) every couple of days and leave off the medicine as your fish are sensitive to it. Try getting some liquid vitamins for the fish. It might strengthen them enough to overcome the ick infection naturally. Ick is almost always caused by temperature changes. <>>><

Should I put some type of drops in the tank to prevent disease?
Dr. Fish
SanDiego, Ca USA - Mon, March 18, 2002

The only product I would recommend is "Stress Coat" and that's when you introduce new conditions to the tank -- i.e. new fish, large water change, new plants, etc. <>>><

I have been having a lot of problems keeping corys..They live for 2 days and then they die.The first 3 that were killed i just throw away but after the next 3 starting dieing i put in bag to take back to the store..I have 5 black tetra , 5 headlight tetras ,1 neon , 2dwarf frogs and 1 molly..This morning i got up and seen one of my cories swimming very wierd like he couldnt keep his balance so i scooped him out and noticed his back fin was gone..Then remembered making a comment to a friend that the last 3 didnt have back fins on either(I thought they may be the first to rot)but this one was still alive and trying to swim..Fin rot wouldnt happen overnight and this backfin was almost completely gone..Do i have a killer in the bunch of fish i mentioned..They hang out under driftwood with the frogs!!!!would they bite off the fins

I am extremely interested in breeding fish. Over the past five years I have had prodominitly Pirhana's. During this time I have aquired a 90gal, 75,30,20,10 gallon tanks. With my breeding I have started with what I have heard is easiest live bearers(mollies) 2 Female silver 1 Male silver 1 Female black this one apears to be pregnant from purchase. They're in the 30 gallon tank with 2 Aqua clear filter 200 and 150. both hooked into undergravel filter system. Have breeder net set on back of tank but, have not put B/molly into yet when should I do this. So the babies won't get sucked in? If I don't aprox. how many on an avg. might survive? My 90g tank has 1 14inch pure tiger oscar 1 10inch Jack Dempsey 1 4inch African cichlid. This African cichlid alway's fight w/ either the jack or my 18inch pleco, baby 2inch pleco also show's sign of harrasment. This tank only used to dwell Jack and 7inch pleco but Jack killed the pleco in 20 gallon tank while in the process of moving. Recieved the Oscar and 18inch pleco from friend and bought African cichlid after to try and sort of have more fish per space. Is this community a good mix or should the african cichilid be eliminated? I Also would like to find a place to order rare cichlids via mail African or South American. Feel skilled only to a certain extent please help.
Linc, Nebraska USA - Tue, March 19, 2002

The mollies should breed without any real help. Watch for the black spot on the belly to grow in size. With practice, you'll get a sense of how big it should be before putting her in a breeder net. If you keep only mollies in the tank, you'll be full up to your eyebrows in them shortly. Cichlids are born to fight, they are very territorial. They should be kept to themselves and not in a community tank. You could try or for rare cichlids and catfish. I have not bought from these sites, so no guarantees. <>>><

The water in our fish tank turned a dark dark green. we could'nt even see the fish. we used a product that was supposed to make the water clear. we tried it since we had tried everything else. it worked for a few hours and now its starting to turn green again. What sould we do? all we have in the tank is 1 plant and the gravel.
Surrey, Canada - Wed, March 20, 2002

What sort of lighting does this tank have? It sounds like you have an algae bloom from bad water conditions. You may have to redo the entire tank to get rid of it --change water, gravel, filtration plant, etc. <>>><

I have had a 30 and a 50 gallon fish tank in the past(fresh and Salt water) and have decided to set up the 50 gallon (Fresh water) for my daughter, but I was talking to our local pet store when we were getting some new items, and they said that they do not reccomend using a bottom filter anymore. I thought to myself that this is strange, they were the same people that told me I needed it in the past. Can you advise what would be better to use it or not? Thank You.

have a 29 gallon tank with a great community, ive had it for about 2 years now. My Pleco(ugly)is fat and the silver dollar is well, he's huge, the neon tetras are fat too and my two gouramis are almost 4 inches long. I noticed that alot of people who write have water problems. It takes time for the water to stabilize huh! I have both undergravel and a newer top fin overflow 30 and never have problems. I was wondering how long activated charcoal in both the filter cartridges and the undergravel outputs needs to be changed. Top fin says its okay to reuse the filter cartridges if you want and since theyre $$ and I have -$$ that works out well! Also the stone areators clog constantly, do you know of a brand that doesent?? and how long should the light timer be on/off? I have it about 14on/10 off. Thanks e-mail open 2 Jude

Puyallup, WA USA - Tue, April 2, 2002

You don't have to religiously change filter cartridges as the biological filter does as much work as the chemicals. The charcoal is to keep the water clear for viewing. Your lighting sounds fine. <>>><

i have an established 30 gal. undergravel and mechanical filter. when my last fish died i decided to start over. i emptied the tank completely and changed the filter, although i left the undergravel filter undisturbed. i filled the tank and let it sit a week. then i got three zebra danios to build up the nitrates/nitrites (sorry, i'm not sure about the wording on that one). it's been two weeks since i put them in and they are thriving! they have turned from a black and white color when i purchased them to a pretty black and pink. they are doing great. my ammonia level is zero, but the ph is extremely low. should i put in some ph ajduster, wait longer? i've done my research but i can't find anything about this problem. thanks for your help, annie

I started a fish tank a couple years ago. We discontinued it's use for a while and now I want to start it up again. It's a five gallon vinyl tank. Its a half hexagonal shape with 2 riser tubes and lots of air tubes that aren't that clean, and although they're supposed to be clear, they're not. The ends of the air line tubes are kind of stretched and are a little big for the holes. Can I salvage this one or is it not worth it and I should buy a new one? Also, about how many neon tetra sized fish can live in a 5 gallon tank?
Chicago, IL USA - Sat, April 6, 2002

You can salvage the tank. The air tubing can be replaced if they don't fit well. Allow one inch of fish per gallon of water. Sicne neon tetras are pretty small, probably eight is enough <>>><

My favorite old goldfish has been in a tank that measures about 30x12x12 for over ten years. We just discoveed a small leak in the tank about 3 inches from the top. The tank is glass with glued seams. I quickly put several very large cable ties arounr the tank to prevent it from coming completely unglued and discovered that this competely stopped the leak. It doesn't look nice so want to permanently repair the tank. The local pet shop said I had to compltely dismantle the tak and re-glue all the joints. Do you have any other suggestions for an easier fix? Bob Freed
wehum <>
Pittsburgh, PA USA - Sun, April 7, 2002

Sorry, your local pet shop is right. You should dismantle the tank and reseal it with aquarium sealant (100% clear silicon rubber) which you can get at your local pet store. You need to let it dry for 48 hours before you can add the water back in. You can try lowering the water in the tank a few inches below the point where it leaks and only seal the section that you know leaks...but you'd have to make sure it doesn't get wet so it drys thoroughly <>>><

What is ick that fish get, I need to know what it looks like, how it starts and how I can treat it. I have never had this problem before and I am wanting to take care of it before I lose my fish, I think they may have it. Thanks.

are koi fish lucky?
morris, ct USA - Thu, April 11, 2002

Among the Chinese businessmen, fancy carps are often reared for " Good Luck" . There exist quite an elaborate philosophy about the number of carps that should be reared- usually in multiples of nine ie. 9, 18, 36 and so on. When one or more fish in the pond died for whatever reason, the owner must immediately buy new ones to make up for the same number- or else it will be bad luck. Another superstition is that all koi have to be given names immediately or they will die. Expensive hobby <>>><

My son has a 25 gal tank with 2 swordtails 2 angels 2 tetras 3 mollies 1 tricolour shark and a blue gourami.

I treated this water with quick cure and salt and I am hoping he will rest and recover - any suggestions would be appreciated.

Hopewell, va USA - Fri, April 12, 2002

It is quite unlikely that your goldfish is pregnant. Goldfish become "heavy" rather quickly with good feeding and will grow very large. If you wish to keep your fish within your five gallon tank, only feed it what it can eat in about 1 minute. <>>><

Most fish will eat any fish that they can get their mouths around. A few exceptions: I haven't caught a coryadora dong this trick yet. Fish will ignore other fish that are not part of their family. Therefore, a tetra won't notice a swordtail as they are not in the same family. Certain fish should not be combined with others - goldfish and angelfish are often combined in a community tank with sad results. <>>><

Hi, I have two platties, well actually I had three one died in April. Last night I noticed there were two baby platties in my tank! I have a small tank 5 gal, I was so surprised to see these little fellows because I had no idea one platty was pregnant, I thought it was just fat! I have a couple questions, could my platty only have two, I mean is that normal? or were the rest eaten :( I see they are doing ok because they swim around and to the surface with the bigger guys, and they love to eat flakes, but I don't know when they were born. These little fellows are about a little less than half an inch. I can see the black in ther tails, and fins--super cute. But what is the size when they are born? With the size they are now will the parents eat them? I doubt the tetras will. I am afraid to take them out but with the little live plants that are in the tank I hope they survive. My last question is more or less how fast do they grow. I hope that with the tank light this will keep the water warm so that can help them grow a little faster,(not to much of course) I see they like it because they dare to go to the surface. Hope my babies survive :) Thanks

I have recently noticed lots of little white/clear worm/larvae looking creatures slithering around on the glass, each one seems to have a little brown spot on them too. I know they can't be worms though, because they are apparently turning into little flying gnats or water bugs or something, they have wings, antennae and their bodies are green.

Also, I was wondering if they could have been introduced via algae discs, if not any other way.

Hi, I have just purchased a 20 gallon aquariam kit with heater, filter, conditioner etc. The aquariam has been set up and running for 4 days and all we need now is some fish. I am looking for a hearty long-living fish that is medium to large in size and colorful. I would like to have approx. 4-5 larger fish altogether but am unsure which can live together well. What do you suggest? Also< I currently do not have a salt water tank and have heard they are harder to care for than fresh water tanks. Is this true? I do not have much experience with aquariams/fish and am grateful for any help you can offer. Thanks, Robin

i have fish that have ick. i treated them with a tablet you just put in the water and kinda fizzes like alka seltzer. as you can see i am a newbie with fish. what i would like to know is how long do i treat the fish, and what is the best stuff to use? also i have a 30 gallon tank set up with no fish in it at all yet. i am planning on transfering the fish into that tank as i have to many in my 10 gallon. would it be better to transfer them now or wait till the ick is gone? id really appreciate any advice you could give me.

I am still new at this fish tank stuff. I have 5 goldfish and 2 plecos in a 30 gallon tank. I have noticed that my biggest goldfish have got some scales missing. I didn't know if this was due to growth or if it's some kind of disease. I am still learning about ick too and was wondering if mine get it should I remove the plecos? Also, my largest pleco is trying to latch onto my other fish. Should I add algea tablets? Thank you for your time. All your advice is appreciated.

Feed your fish some boiled lettuce. Goldfish sometimes lose a few scales without consequence. Ick is usually caused by extremes in water temperature, too hot, too cold. Hopefully, you won't have to worry about it. <>>><

I got two nickle sized angelfish about eight months ago. I've kept them all this time without any problems. About a month and a half ago my tank started leaking so i had to transfer my fish and rocks,plants etc.. to a new tank.I did this without having any problems with my fish. Now I had the same problem five days ago and i had to change my tank again.(the manufacturer of the tanks had a defective bunch i was lucky enough to get two of them) Everything seemed to be fine then three days after the switch one of my angelfish started acting strange (gasping at the surface,hiding,swimming crooked and eventually upside down) I moved him to a sick tank where he died. The next day my other angelfish was fine, I fed him and he ate no problem then i saw him acting the same way the other angelfish did before it died. I never even had a chance to try tohelp him... he died This all happened within a HALF AN HOUR!!!! What happened?All my other fish in the tank are fine. The angelfish did not have anything visibly wrong with them. They both just died very suddenly a day apart from each other.Please e-mail me directly with your opinion on this matter. Thank you.

Anyways, besides the point. I am breeding the velvet fish, and i know i have to get a breeding tank, and also a bigger normal tank for when my velvets have their children. I've searched the internet for hours looking for a site to tell me what i need to know on breeding and, what it looks like when the female is pregnant, and how long into pregnancy will she have her young ones. I haven't found a thing. Can u help me please, i need to know everything i can know. Thank you! Katie

HELP, my roommate has a fish tank but he doesnt take care of it to well. We have 2 Oscars 1-Red, 1-Tiger both are approx 7mths old and we also have a Placo about the same age. Recently I have noticed that at the bottom of our tank there seems to be these little white "flea-like" things crawling around on the floor. When my roommate feeds the fish he drops a bunch of food in there then just leaves. The uneaten food sinks to the floor and dissolves. And thats when the (I call them) "water fleas" come out. There are so many of them it seems like it cant be good for the tank almost like a hostile takeover. Anyways my roommate believes these things are bacteria and belong in the tank, I however on the other hand dont think they belong in there. Can you help me and trying to get this problem resolved.

Hello, I was wondering if it is possible for a platy to give birth over the course of several days. I have a platy who was or still is pregant, while doing a water change she started to give birth, I only noticed one little frye at the time, But she still looked very pregant. Than about a week later I noticed a few more babies in the tank, and yet the female platy still continued to look pregant. Is this normal?? I do realize that the other fish in the tank have probably eaten most of the babies, but why does the platy continue to always look pregant. I have 2 plates, 3 mollies and one alge eater and live plants. Thanks Amy

I am new at this hobby and have just purchased a 20 gal tank. So far I've stocked it with two tiger barbs, a red tailed shark, and three other fish. The only problem is that I do not know what the other fish are. I wasn't really concerned with the type when I bought them. I just asked a petshop employee if they would do well together and he told me that I should have no problems. Now I want to know what the other three fish are so I can research them to get more fish. One of the unknown fishes looks almost exactly similar to a black skirt tetra. The only difference is that his tail and rear fins are much larger. Another of the unknown fishes is exactly the same as the first unknown with the only difference being that he is all white and his fins and tail are clear. The third unknown is built like a tank. He is long but solid. His coloring is speckled black with what appears to be some clear in between. His mouth is located at the top of his head which I believe is for surface feeding. If anyone has any idea what these three remaining fish might be please help me out!!!

Michael <>
Livermore, Ca. USA - Fri, June 28, 2002
A 12 gallon tank will only support one or two crayfish. Any more and they will kill each other off. You can feed them pieces of raw fish, regular fish food, chicken, boiled lettuce. Crayfish need hiding places otherwise when they moult they will be eaten. We give ours coconut shell halves (after they have been cleaned and boiled) and pieces of clay pots to hide under. We have successfully kept five crayfish in a 35 gallon tank as it had lots of plants and hiding places. Otherwise, you end up with one crayfish--the survivor. They are hardy creatures but prone to climbing out of the tank and thereby committing suicide. Make sure there are no air tubes that the crayfish can climb on in the tank. Good luck, Marisa <>>><

My tank water keeps getting brown and cloudy. I'm not sure how to correct this. I have a 55 gallon freshwater tank, no plants (maybe that is my problem) one baby African frog, a loach, a giant goldfish and four other small fish (which I cannot recall exactly what they are, just added last week).

HI I have been keeping a 30 gallon tank for about 7 months. In this tank was a moonlight gourami, A polypterus eel, A Male Kribensis, and a Green Severum, The Kribensis was always a bit aggressive about owning the bottom of the tank but all of the fish get along fairly well. I realize that some of these fish get large and I will Have to upgrade the tank but for now they are juveniles. Anyway, I bought a jeweled cichlid today which the aquarium shop owner said was fairly docile for a cichlid. As soon as I put him in the tank the strangest thing happened. The Moonlight began attacking him! He would occasionally try to get away from the conflict but when pursued by the gourami he turn around and fought....Then the Krib got in on it....Now I had an all out brawl on my hands and no fish were trying to run they were all chasing each other in tight circles and occasionally pinning each other to the gravel. So I put some food in the tank and turned out the lights. Will these fish let up or is somebody going to end up dead? Please help, I don't like dead fish...Thanks

Obviously, you upset the balance of territory in your tank. I highly recommend removing your jeweled cichlid. <>>><

A good quality nonsoap plastic scrubby and elbow grease. Without the fish, vinegar, hydrogen peroxide and salt mixes sometimes help. <>>><

I'm getting tired of waiting for my water to be conditioned, i heard you can just go and buy distilled water and use that without having to condition it. Can i do that?

Also, if I do a complete water do I feed my algae eaters? Putting algae tabs in the tank proved unsuccessful as the mollies polish them off long before the algae eaters ever get to them...

Try giving some boiled lettuce to your fish. <>>><

I have a 26 gallon bow front fish tank. I have 2 large marble angelfish, 2 medium blush angelfish, and 1 smallstriped angel. I also have 2 large orandas, 3 small orandas, and a black moor. This combination has been set up and doing great for almost a year, however, recently I've been reading that they aren't a good combination. Should I be worried about this even though they appear to be doing great??? Also, it seems like everytime we try to add different fish or plants(we use live plants) they get one of the run of the mill diseases(ie. ick, popeye etc.) but when we leave them alone they do great... is this caused from stress?? Thank You for any help you can provide, Lindsay

Changing a tank's environment when it is stable and working well causes stress for the fish. If it ain't broke, don't fix it. <>>><

New to this aquarium stuff. Can I mix tropical fish with warm water fish? Have a 30 gal. tank. Would like fish that grow to 4 to 5 in. What type are hardy and fast growers? Thanks.

USA - Tue, October 1, 2002 Gouramis - they are hardy, pretty and grow to 4 to 5 inches.

How fast do koi fish grow. I'm keeping two baby koi in a small fish tank, and I would like to know how long I can have them in there for. Thanks for the help.

Depends on feeding and size of the tank. The more food, the larger the tank, the faster and bigger your koi will grow. <>>><

I am wondering if i put other fish in with my betta that eat different foods if they will eat their own and not the others?

Bettas will taste any food to see if they like it <>>><

I have a platy and the stomach looks a little bigger than usual but I don't know whether it's pregnant or sick or what. I actually don't even know if it's a girl. If you could give me some info or a website where I can go to see what a pregnant platy looks like I would greatly appreciate it.

Personally, I like platies with my bettas, but I have heard that some folks keep bettas with goldfish without harm.<>>><

Can I glue some items such as weeds and stones together and then put them in the fish tank without killing the fish????

Use aquarium sealant /silicone. <>>><

I'd like to build my own tank. how do i glue the glass or acrylic together?

RC, Ca USA - Fri, October 4, 2002

Use aquarium sealant up to 30 gallons. After that you need special bracing. It is not cost effective to build your own aquarium and generally not worth the effort unless you want a special size or shape.<>>><
