So I was up to no good (looking around at the lfs) and ended up buying a little 4-5" red cherry flowerhorn, with a nice sized kok and great finnage. I added him to my 320 of amphs, etc that I'm growing out. At first not much, the other fish just checked him out and he checked them out. I stepped away to take care of a few things on the computer and came back 15 minutes later to my trimac, whopping his butt... The trimac is only a tad larger, but torn him a new one quite quickly. I moved the trimac to the sump for now. I had an incident a few weeks ago where a festae's tail was bitten off and I think I may have found the coulprit. My question is, will keeping the trimac in the sump for a few days, rearranging the tank and reintroducing him possibly put an end to his terror, or at least ease it?
