He eats like a champ!!! I have him on a mixture of Krill, Prawn, Silversides and anything else he sees in chunks that looks interesting. I've had him for about a year and a half now. All my fish are actually "trained." Its kind of a learned habbit, when I go into my closet next to the tank the fish come up to that corner because thats usually where i go to get the food to feed them. So everytime i go in the closet the lion is up at the top looking for something to drop in. He's great! My favorite fish in the tank!
