Adults live in coastal waters, mostly around coral reefs. Usually seen well above the bottom, frequently in groups. They feed on a combination of plankton and bottom-dwelling (benthic) animals including fishes, crustaceans, worms, gastropods and cephalopods, mainly at night. Young individuals are usually found over seagrass beds. They feed primarily on plankton. Spawning occurs throughout the year, with peaks at different times in different areas.
