Sinh học     Tự điển (thí dụ epibenthic)

Occurs 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). Feeds on zooplankton while hovering 1 to 2 m above the bottom. Swims away from danger rather than retreat to its burrow.

Monogamous mating is observed as both obligate and social (Ref. 52884).
