Hello. I'm growing out a male, marble montoro in a ~100 gallon by himself. My goal is to get him into my 540 but I don't want to risk it now. He's about 7-8" and doing well on cut shrimp and pellets. I would like to add a some smaller tank mates to get him used to other fish. Should I worry about him trying to eat them? I have a 4-5" yellow tail chalceus and some albino hecklii at about 3.5". What do you think?
