+1 to that. They are mostly bottom feeders and if kept well fed should only want to eat what you fed them. HOWEVER I wouldnt expect him to leave the other fish alone that do fit in his mouth. It will eat any crustacean in the aquarium. They are more nocturnal too so while your fish are resting, JAWS is cruising.

Nate, what does your "shark" eat. The one you converted over? That might work.

Fish included? I was wondering if your catfish/shark would be a candidate that wont eat his fish/corals.
