I have a pleco, an extra-large oscar, a pictus catfish, and several guppies. My tank is 100 gal, runs 2 heaters, runs 2 filters, and is cleaned every other week or so. My oscar is an albino tiger oscar. I would like to add more fish to the tank, but I don't know what to add. I know my oscar will try to eat anything it can get in its mouth, so what are some types I could raise in my 29 gal and then release into the 100 gal? Would more pictus catfish be ok since I know they are schooling fish (plus my oscar no longer views them as food, at least the one in with him)? And he's seemed to stop eating live fish, excluding the pictus, cuz he tried that one.
