Adults inhabit lagoon and seaward reefs (Ref. 9710). Each group of fish consists of a breeding pair and 0-4 non-breeders. Within each group there is a size-based hierarchy: the female is largest, the male is second largest, and the non-breeders get progressively smaller as the hierarchy is descended. If the female dies, the male changes sex and becomes the breeding female, while the largest non-breeder becomes the breeding male. The maintenance of size differences may avoid conflicts, because subordinates do not become a threat to their dominants (Ref. 47841). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Maybe found in shallower depths than A. ocellaris. Associated with the anemones: Heteractis crispa, Heteractis magnifica, and Stichodactyla gigantea (Ref. 5911). This species has been reared in captivity (Ref. 35404, 35413, 35420).
