Indian Ocean: from East Africa and islands of western and central Indian Ocean to Andaman Sea, Cocos-Keeling Islands, Christmas Island, and western Indonesia (western Sumatra, Java, Bali ad Nusa Penida).. According to Randall, pers. comm. 1995 Chaetodon trifasciatus occurs only in the Indian Ocean while Chaetodon lunulatus occurs only in the Pacific). DNA (from tissue samples) expected to further distinguished two distinct species (Chaetodon lunulatus and Chaetodon trifasciatus (Ref. 86689).

Occur in coral-rich lagoons and semi-protected seaward reefs. Territorial and aggressive to other Chaetodon. Small juveniles secretive in corals (Ref. 48636). Swim in pairs. Feed exclusively on coral polyps, particularly of the Pocillopora type (Ref. 5503, 48636). Oviparous (Ref. 205), monogamous (Ref. 52884). Form pairs during breeding (Ref. 205).

Distinct pairing (Ref. 205). Monogamous mating is observed as obligate, geentic and social (Ref. 52884).
