Live in shallow protected coastal waters to deep, somewhat silty habitats. Often with deep shipwrecks (Ref. 48637). Adults are found singly or in small groups and occasionally in large schools in some areas. Juveniles occur singly or in small groups among mangroves and inner sheltered lagoons while adults move out to open waters over sandy areas of deep lagoons, channels, and seaward reefs to a depth of at least 30 m. Feed on algae, invertebrates and small fishes (Ref. 89972).
