I forgot, I dontknow what your feedig him, but try to get him to eat silversides, there a bit messy, but feeding every other day is alot easier. I found if I feed mine 3-5 full sized silversides every 2 days hes as happy as can be. Just hangs out enjoying life! At onetime I feed him krill, he was always hungry, even after I feed him daily, and his stomach was always blown up!
