Inhabits subtidal reef flats, and lagoon and seaward reefs to a depths of at least 27 m (Ref. 1602). Found in coral, rubble, seagrass (Ref. 41878, 58302) and weedy areas (Ref. 9710). Benthopelagic (Ref. 58302). Found singly or in small groups (Ref. 9710). Feeds on a variety of benthic encrusting algae, e.g., Padina (Ref. 37816) and seagrasses. A protogynous hermaphrodite which may only have secondary males. Caught with nets and other types of artisanal gear.
