 It is predominantly an inshore fish, inhabiting reefs down to depths of around 100 m in both coastal zones and offshore islands, often venturing into estuaries and sandy bays as juveniles.The bigeye trevally is commonly found in large slow moving schools during the day, becoming active at night when it feeds, taking a variety of fish, crustaceans, cephalopods and other invertebrates.The fish is known to move from a more crustacean dominated diet as a juvenile to a nearly completely fish dominated diet as an adult.
