mine loves mysis shrimp, I just got hime two weeks ago. Im trying to get him to eat the silversides i got and i bought some mussels today also, well see how that goes tonight, but so far mysis shrimp has been my only success. When I feed the mysis I try to keep it clumped together, so he can get it all in one bite, hes a little slow so put it close to where he is, or my triggers will eat the food on him.
