redbelly piranha

I don't really know anything about Piranha, but I am almost certain that a 10 gallon isn't even close to being big enough for even just 1 piranha.

well, a pirahna is a characin like a tetra so you might not get much help in the cichlid forums but they are more similar to the requirements of cichlids so you might try. I believe red bellies get somewhere in the 6-8" range when fullgrown. a 10 gallon is definitely too small. It would be similar to making you live in a Motel 6 bathroom all your life, you could move around but how happy would you be? You could probably get away with a single in a 29 gallon but that's just a guess if I was correct on the size. First of all, make sure they are legal in your state. I know they are not in Oklahoma and most warmer climate states. Feeder goldfish are not accepted as nutritious food so you'll need to look elsewhere for this. Just going from documentary shows I've seen, I don't think pirahna will eat "healthy" live food anyhow. They would more likely eat fresh meat like beef heart or something which is much easier to keep than live feeders anyhow. I do have a book at home that has pirahna listed so I'll repost when I get home with some better specific info if someone else hasn't posted. Do some searching on the internet for these fish to get a better idea of their requirements. Kyle

piranha, are hard to keep, though rewarding from what I have read. You will have trouble finding a state in the US that lets you keep them now with the fear of introduction into the wild especially in the southern states. They are very dirty fish as are most of the larger fish when it comes to waste etc. Much like oscars and Jack Dempsy. As stated before live feeding isn't the primary diet beef heart and other fresh meat would make a much healthier diet than feeder fish. Feeder fish are also risky for introducing disease to the tank.
