Benthopelagic (Ref. 58302). Occurs in lagoon and seaward reefs from the lower surge zone to a depth of at least 30 m. Solitary juveniles found among rocks or coral (Ref. 58534) of shallow protected, sometimes turbid reefs (Ref. 1602, 48637). Feeds on leafy macroalgae. It possesses, fewer and larger pharyngeal teeth, compared to the other Zebrasoma spp. (Ref. 33204). Diurnal species (Ref. 113699:32); courtship and spawning takes place from morning to afternoon and is often confined to ebb tides (Ref. 38697). The species is never poisonous (Ref. 4795). Minimum depth reported taken from Ref. 128797.
