Indo-Pacific: East Africa to the Hawaiian and Tuamoto islands. However, the Pacific population has been recognized as a distinct subspecies (Chaetodon trifasciatus lunulatus Quoy & Gaimard, 1825) by Burgess (Ref. 4855) while according to Randall, pers. comm. 1995, Chaetodon trifasciatus occurs only in the Indian Ocean, while Chaetodon lunulatus occurs only in the Pacific.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 13 - 15 cm
Max length : 15.0 cm TL male/unsexed; (Ref. 5372); common length : 12.0 cm TL male/unsexed; (Ref. 5450)
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).
