Well for me I have to feed a decent amount because I have 2 clowns, a court jester goby, and an unusually timid 6 line wrasse (in comparison to what people have told me). My smallest clown is a rescue from Petco. He was so small and was getting nipped by the other clowns in the tank. Lucky for me he was eating and didn’t have any spots so I quarantined him and dropped him in. For him I have to crush up flake food so he can eat it. Unfortunately that causes higher nutrients and I need a way to take care of that.
