Yes, as Sonicblast12 said, fresh seafood. I used to goto the fish counter at my local supermarket and pick up a few NON cooked shrimp at a time. About once every other week I would get a small clam and remove one side of shell and place in tank, my triggers would clean it so it looked polished. The key is variety here, squid chopped into small portions, shrimp as I said, and any fish that was on sale (make sure its ocean fish, not lake fish). Believe me, your trigger will be in heaven!
