I have carberryi anthias, they are a more sensitive species so I feed 4x a day a variety of flakes, NLS pellets, frozen cyclopeeze, baby brine shrimp, and PE mysis shrimp. I know people say you can "get away" with feeding once a day but any research on the fish will say they like to feed multiple times a day. I think it's best to mimic their natural feeding habits.
Just my 0.02
