Pirranha

[demonmagus]

Is their any type of piranha out there that would be good by itself, and doesn't grow to like 2 feet

 

[Alex_]

There is one that is called a Black Rhom that grows to about 18''

im pretty sure that it does well by its self.

There are quite a few species of piranha that fit that description, espically in the Serrasalmus genus. I dont intend to sound rude or judgemental, but Piranhas arent for inexperienced fishkeepers. And really shouldnt be kept in anything smaller than a 75 gallon aquarium.
