Yes he will.... I have a dogface and he eats all inverts, except my urchin, and for some reason the remaining fire shrimp (they're buddies, but I think he is just leading it on....he ate the other one right away) I buy snails on ---- for the tank so he always has something to munch on,so far he hasn't bothered the corals. He is only in the reef tank, cause I had a crash in the tank he was in. On the other hand he had a Choc Chip Star in his tank and never touched it. So he may not, but I would plan on on him eating anything you put in there.
