My mbu is finally living it up in the 750g. He was in a small hospital tank for the last 2 weeks healing from a bacterial infection and injuries caused by his tankmates while I was on vacation. Minus 30 some odd tankmates later (mbuna cichlids) he is now happy and king of the tank.
He eats shrimp and mussels for now and Sunday the local grocery is getting in some clams for me.
