So I have this beautiful 5-6 inch Red Devil (pics to follow soon). I want to make him the centerpiece for my 75 gallon tank. He is so so on the aggressive scale, but I expect that will ratchet up as he grows. I was toying with the idea of putting 3 silver dollars and 2 cons in with him. They are fine right now, but what do you think would happen if I tried a breeding pair of cons in a 75 with a Red Devil? Would they simply not breed? Any other stocking thoughts? I do want something else in the tank with him, while keeping him the focus if possible. Anybody experience small tankmates in a 75 with a RD before?
