I agree with Opcn, although, it could be used as a loose rule. Someone could see that and think a piranha would be fine in a 20 gallon, thats sort of what I meant. This post was mainly to ask Lou why he has a school of Red-Bellied in a 10 gallon if he is a self-proclaimed, so-called "expert" of piranhas.
