Adults occur in deep lagoon and seaward reefs where they feed by rooting for crustaceans and fossorial invertebrates in the sand but they also feed on small fishes (Ref. 9710, 90102). Small juveniles live among the tentacles of jellyfish (Ref. 9710). Adults form schools and are also noted for their behavior to closely swim around sharks and other large fishes, and also follow divers (Ref. 10361). Juveniles particularly display this piloting behavior to gain protection from likely predators (Ref. 9710, 90102). Marketed fresh and salted or dried (Ref. 9283). Juveniles are used in the aquarium trade. Minimum depth reported taken from Ref. 128797.
