Found in subtidal reef flats and lagoon and seaward reefs. Juveniles occur inshore, found among branching corals while adults found in areas of mixed sand, rubble, and coral (Ref. 9710). Large adults in deeper water (Ref. 48636). Maximum length beyond 45 cm TL is unlikely, with largest measured individual at 37 cm TL (Ref, Feeds mainly on small invertebrates, especially crustaceans, polychaete worms, mollusks and brittle stars (Ref. 9823). Diet changing from primarily demersal planktonic crustaceans to hard-shelled invertebrates with growth (Ref. 37816).
