Generally uncommon species found in steep outer lagoon and seaward reef slopes (Ref. 9710, 48637). Maximum depth reported at 40m (Ref. 37792) Occurs singly or in large schools (Ref. 9710, 48637). Usually seen swimming steadily along upper edges of drop-offs in pursuit of plankton (Ref. 48637). A semi-pelagic fish that feeds on zooplankton, but remains over or near reefs. Also feeds on algae (Ref. 30573). It is cleaned by Labroides and sleeps on reefs at night, taking on a disruptive mottled pattern (Ref. 10671). Caught with nets (Ref. 30573).
