Adults occur in outer reef slopes, also inhabits lagoons and bays. Usually in pairs as adults and in small aggregations as juveniles, Ref. 48637. Monogamous (Ref. 52884). They feed on zooplankton while hovering 1 to 2 m above the bottom. They swim away from danger rather than retreat to its burrow.
