Adults inhabit hard substrate areas of clear lagoon and seaward reefs from the lower surge zone to at least 67 m and feeds on filamentous algae. Solitary or in groups (Ref. 90102). Monogamous (Ref. 52884, 48637). Benthopelagic (Ref. 58302). Small juveniles shy among large corals (Ref. 48637). Territorial species. Common throughout Micronesia and hybridizes with the rare A. achilles. Size of metamorphosis from the postlarva stage to juvenile is 5.5 to 6 cm (Ref. 9267). Minimum depth reported taken from Ref. 128797.
