Well I have one in my tank and there are times he goes in "time out" for his over aggresive behavior.

I've heard people say they give their fish time out's. We don't usually have to do that.What do u do for time out's?

To give them time outs you put them in a little floating breeding pin thing. Usually it's used for holding females to release their fry into. It's really good though for punishing an aggressive fish. I find that in my 90 gallon tank which has tons and tons of rockwork (I've collected and cleaned quite a few rocks, I couldn't even fit them all into the 90 gallon if I tried so some sit aside or in the other tanks) I have very, very little aggression. Strangely though it is in the hospital tank (occupied by 4 female convicts and currently one healing wounded male Lombardoi/Kenyi Cichlid) that my fish are total wusses in. I think they pick it up from the convicts; those scardies. (And yes I know convicts are usually real aggressive but mine are quite the opposite). Oh and just the latest news from me. One of my female albino Socofoli's is holding and probably soon going to release her fry. The last 2 batches strongly appear to have been hybrids between the Julidochromis Marlieri and the albino Socolofi, but it just seems so unlikely and I am still in doubt as to who the parents are.
