OK, so, I used to own 5, 4-5" red bellies when i was in University. I had to give them away when I graduated because I didn't know where I was going to end up (they went to a good home). Now that I'm rich and successful (HA! yea right..), I want to get back into Piranha keeping. I am thinking about going for a solo Black Piranha from the Xingu River to get a more aggressive, show fish. I would like to use a 55 gallon because it fits where I want the fish. Does anyone see any problems with me switching from the shy rbps to a more exciting/aggressive Black Piranha? Any help would be greatly appreachiated.
