I have a small fuzzy dwarf lion which im going to attempt to get him eating off prepared food instead of live food when he gets into his permanant tank. Anyways the LFS gave me some ghost shrimp and one small gold fish. He didnt go after the goldfish(maybe it was too big for him) but he eats the ghost shrimp as soon as he spots them. Are they nutritional? if not, what is a good LIVE and CHEAP food that I can feed him for the time being?
