What kind of food the Nassau grouper eats?

Adult Nassau Groupers generally eat a diet of mainly fish (parrotfish, wrasses, damselfish, squirrelfish, snapper and grunts). Juveniles, on the other hand, eat a diet composed mainly of crustaceans (crab, stomatopod, hermit crab, panulirid lobster, and caridean and panaid shrimp). These juvenile groupers are usually found around coral clumps covered with macroalgae and over sea grass beds.
