Occurs in clear seaward reefs, usually in groups (Ref. 9710). Benthopelagic (Ref. 58302). Feeds on filamentous and small fleshy algae (Ref. 9267). Monogamous (Ref. 52884). Spine in caudal peduncle may be venomous. Size of metamorphosis from postlarva stage to juvenile is 6 cm (Ref. 9267). This species sometimes hybridizes with A. nigricans (Ref. 9808).
