Adults occur in lagoons and seaward reefs to a depth of 30 m, prefer coral-rich and clear water areas (Ref. 205). Benthopelagic (Ref. 58302). Encountered singly, in pairs or small groups (adults often in pairs; juveniles solitary and inshore). They feed on filamentous algae, small invertebrates, coral polyps, and fish eggs. Oviparous (Ref. 205). Form pairs during breeding (Ref. 205).
