I cannot sex Piranha's. You are probably best to buy some, wait till you have enough money, then buy some more within a 3-4 month period. Piranha's are just like tetras. They need to be in schools. Thats the cardinal rule.

They are alot more skittish at first to keep them alone, or small group. But given time they become more active. You need a 55 to keep a solo RB then atleast a 90 to keep 3 or more...
Claw;1312634; said:I callled the LFS yesterday and he said that it costs $40- 3 and 1/2 inch piranha, so I think that I am just going to think about buying 2 for now or if you say 1 is fine then i do not mind doing that. If I am going to buy them it will probably be after the 26th of this month or maybe after the 17th (exams finish and School closes up for holidays); on the 19th I am going out of the country for a week so that is why I thought it would be better to buy the piranha after I come back. I asked another LFS what equipment is available to cool the tank and he said that there are chillers but they cost a minimum of $700 ( which is way too expensive for me). I have a heater already and it can be preset to keep the tank at a certain temperature so I have got the winter situation under control, only problem is to cool the tank.

Has this dealer told you if they were "pygocentrus" or "serrasalmus"?
Like it has been stated, Serra's are solitarty fish (with some few exceptions)while the 3 species of pygo's (red bellies) are the only piranha's that can be kept in groups but that by no means is a rule. It is true that a solitary young pygo will be shy, but so will a young serra. It takes time before the fish learns that its not in danger...some longer then others.
A 10 gallon tank is by far too small. If you're looking for temperary housing for a small piranha, I've always had good luck with a 20 long
(30"Lx12"Wx12"H) which holds a single serra or pygo for quite some time but if you have multiple pygo's obvioulsy the tank will become too small quickly(serras will usually reach 6" within a year and slow considerably after that, pygo's will grow faster).
Piranhas are sexually dimorphic.
