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.

Biologi     Ordlista (t.ex. epibenthic)

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).

Life cycle and mating behavior Könsmognad | Reproduktion | Lek | Ägg | Fecundity | Larver

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