Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; reef-associated; non-migratory; depth range 5 - 15 m (Ref. 9710). Tropical; 0°S - 45°S
Western Pacific: northern Australia, from Western Australia to the Great Barrier Reef; New Guinea and perhaps further into Melanesia. Very closely related to Chaetodon rainfordi and the two species are sympatric over part of their ranges.

Form pairs during breeding (Ref. 205). Monogamous mating is observed as both obligate and social (Ref. 52884).
