Inhabits coastal areas around coral reefs (Ref. 30573). Feeds on zooplankton in large midwater aggregations. Forms schools with members of the genus Pterocaesio. Oviparous, with numerous, small pelagic eggs (Ref. 402). Often mistaken for juveniles and easily overlooked because of small size (Ref. 48636). Also caught with drive-in nets. Utilized as tuna bait fish (Ref. 30573).
