Habitat and Ecology [top]

Habitat and Ecology:This species is generally encountered on deep outer reef slopes, with populations inhabiting shallower water in cool upwelling areas in the tropics. Both adults and juveniles are usually encountered in aggregations (G.R. Allen pers. comm. 2006). Animals swim up to several meters off the bottom while feeding on zooplankton. The juveniles have been observed cleaning parasites from other fishes (G.R. Allen pers. comm. 2006).
