Pelvic fins long, reaching beyond level of anus. Color: Upper body olive brown, silvery-white below. 3 yellowish white stripes along head and body.

Common on coral reefs usually associated with sandy areas. Adults inhabit outer lagoon reef flats and seaward reefs flats, often in groups. Juveniles are found singly near the shelter of corals on clear shallow lagoon reefs (Ref. 9710). Adults form schools or small groups (Ref. 48635). Feeds on small fishes, crustaceans (Ref. 9710) and benthic invertebrates, primarily polychaetes (Ref. 37816).
