Western Pacific: Cenderawasih Bay, Indonesia.
A common species, occurring in large schools with up to several hundred individuals. Observed to be frequently mixed with Pterocaesio pisang and Gymnocaesio gymnopterus. Often occurs on the upper edge of seaward reef slopes, commonly at depths ranging from the surface to about 15 m, but also sighted as deep as 55 m. Unlike other caesionids, when pursued, it hides in nearby crevices and holes within the reef matrix (Ref. 74965).
