Dark brown (body in life with fine pale blue-green longitudinal lines following scale rows, becoming dots anteriorly on body and on head) (Ref 9808). Small juveniles have yellowish bars and more prominent yellow specks than adults.
Body shape (shape guide): short and / or deep.
Adults occur in coral-rich areas of lagoon and seaward reefs. They graze on algae, usually in groups of 20 individuals (Ref. 5503, 48637). Adults usually in small groups and sometimes schooling. Juveniles solitary and usually among corals (Ref. 48637). Their numerous, small pharyngeal teeth may have evolved in response to a shift in diet from macroalgae to filamentous algae (Ref. 33204). Mature individuals form resident spawning aggregations (Ref. 27825). Monogamous (Ref. 52884). Group and pair spawning have been observed. The flesh is never poisonous (Ref. 4795). Minimum depth reported taken from Ref. 128797.
