Nassau groupers are generalists which feed predominantly at down and dusk. This species has a unique method of engulfing its prey, quickly moving its gills to create suction, or negative pressure, that draws prey into its open mouth. As age and size increase, so do the preferred prey size. Juveniles and smaller young adults prey on crustaceans and bivalves, while older Nassau groupers mainly eat fish, lobsters, and gastropods.
