Is it necissary to feed your bimac live food? I have had lion fish before and switched them onto frozen. Is frozen clam, silver sides and krill enough variety? Should I buy the bimac a treat every once in a while like a sally light foot crab? I feed my 3 reef tank brine shrimp, blood worms, glass worms, black worms, krill, formula 1 and 2, mysis shrimp, squid, clam and 2 other manufactured foods containing various mixed seafoods and am not convinced that is enough variety, so is there any other foods I can give a bimac?
