The Best Filter for a 10 Gallon Goldfish Tank

Will a 20 high be enough? How shold I change them over rather quickly without destroying their bacteria? Also, the only reason that I put two in there is because I didn't want it to get lonely. One of them has a fin on the same side as Nemo that is deformed. All it is is a little peg. I named him Nemo and the other one Coral cuz she died in the movie.
 
well here are some links that you'll find useful:

first, the profile on goldfish

second, when it's time for a new tank, you need to make sure you cycle it. here is a good link about cycling:

the 20 high idea will do for a while, but like it says in the profile goldfish can get almost 2 feet long :eek: sooner or later you'll need to get bigger tanks in order to keep them healthy. The profile page says 90 gallons, which is prety big, and will require a lot of filtration. Basically if you keep them in a small tank they will be stunted, which will lead to an early death. Under the right conditions a goldie will live 15+ years.

One thing a lot of people will suggest is that if you don't think you can afford to get a large tank like that you may want to find somone who has a large tank and let them take care of them. realistically if you want to keep a smaller tank (10-30 gallons) you need to keep smaller fish (tetras, dwarf gouramis, and many more), so you may be well served to try and see if the LFS will take your goldies back and give you a store credit or something so you can get some small fish more suited to a small tank.

that said though, if you can keep getting bigger tanks to fit the fish in, have at it and enjoy :)

good luck!
 
So, is 90 gallons the smallest I can out my Goldfish in? I can get up to maybe 30 gallons in about 6 months if they grow. I can't have a tank bigger than that cuz I live in a small house. My local fish store won't take them back cuz of the risk of disease to their tank. LOL. What should I do?
 
if i remember correctly, these are fancy goldfish? if so, then a 40g tank would be fine with double filtration. fancy goldfish don't need as much room to swim as commets do, so you can get away with a smaller tank if you keep up with water changes really well.
 
They are fancy goldies. I tried to post a picture of them but it was too big. I don't have room in my small house for a 40 gallon tank. I can only get a 29 gallon tank. Should I use a Whisper 60 for it?

Or maybe this:

Or will these do good enough?:
http://www.tetra-fish.com/catalog/product.aspx?id=278 - 210 GPH
http://www.tetra-fish.com/catalog/product.aspx?id=576 - 200 GPH
http://www.tetra-fish.com/catalog/product.aspx?id=283 - 150 GPH
http://www.tetra-fish.com/catalog/product.aspx?id=284 - 300 GPH

2 Fancys will probably be able to live a decent life in a 29 gallon tank, though they won't have a whole lot of swimming room. Keep the decorations to a min to give them max room. On the back of a filter box it will useually give you the GPH reading. With a messy fish like goldfish aim for about 10X the GPH of the tank. So a 10 gallon tank would have a 100 GPH filter. Filter's claims are usually created in perfect conditons so in real life that rating will be a little lower, that is why aiming higher is better.

Also keep some test kits on hand, especially nitrate after the tank is cycled. You will want to keep those nitrates lower than 20ppm.

Also try to get a variety of food for them and make sure it is goldfish food and not tropical food.

Setting up the new tank will be as easy as moving the old filter over to the new tank or at least the filter media. That will move a lot of the good bacteria and help prevent large spike sin ammonia or nitrite.

Even with a big filter it will still be necessary to do good sized water changes. Weekly is best and you can judge the size by the level of nitrates. Do enough of a water change to get the nitrates below 20ppm, though I would still stick to aminimum of a 30% weekly change for the optimum health levels.
