Large planktivorous fishes of quiet waters along reefs and bays, often forming small aggregations throughout the tropics.  The few Hawaiian records are aquarium releases in the case of Platax pinnatus & Platax orbicularis around the main islands, or errant settlers at Midway Atoll.  Juveniles have an extremely narrow profile unlike that of adults.
