Nocturnal species that is usually in pairs or small groups in shallow reef flats of lagoon and seaward reefs to depths of over 30 m. Juveniles occur among rocks of inner reef flats and in tide pools (Ref. 205). Benthopelagic (Ref. 58302). Adults feed mainly on nudibranchs, tubeworm tentacles, and other benthic invertebrates, also on algae and coral polyps. Oviparous (Ref. 205). Form pairs during breeding (Ref. 205).
