I while back i purchased a dwarf lion from rca. He has slowly adapted to eating frozen foods, and im just wondering whats best for him. He was eating mysis then i started feeding chunks of raw gulf shrimp from heb. I ran out last week so ive been feeding him a mix of krill and silversides. Should i stick to krill and silversides or is there something more healthy for him now that he readily accepts frozen food?
