Hello, first time with Convicts. Too small to identify their sex I believe. Store had 3 left so I bought all 3. One is slightly over 1 inch long. One is about 3/4 inch long and the other a little over 1/2 inch long. I am loving them as they are all over a 29 gallon tank (well cycled with a few rams horn snails). They know people and swim to the top when we approach. The largest chases the other two, but mostly chases the smallest. If I am lucky enough that I have a pair that want to breed, I am wondering if I should move them to a 65 gallon tank. My only problem is I can move all of the current occupants of the 65 gallon except for a 10 inch common plecostomus. Would they pester the pleco to death or should I just give up on the idea of moving them to a larger tank to breed and just leave the pair in the 29 gallon and move the 3rd Convict to another tank?
