Found on coral reefs and rocky bottoms (Ref. 3800). Forms small aggregations near the bottom (Ref. 10786). A nocturnal feeder (Ref. 5521), feeds mainly on small fishes, crustaceans and polychaetes (Ref. 3800). Most of its prey are larvae. Flesh considered excellent quality; marketed fresh (Ref. 5217).
