im helping to set up a tank with a freind of mine, and he wants piranah's. what a surpise. well the store i work at just got in a bunch of wild grown redbrested prianahs. SO, what i ask may seem stupid, but since i have never really found piranahs intresting (although these wild ones seem cool) what i want to know is, what would make suitible tank mates for 2 or 3 piranah's in a rather large tank (70 - 100) im actually not expecting any fish to survive, but i am curious if there are any.
