GENERAL CHARACTERISTICS: Their color is white with pair of black bands, second band terminating at end of anal fin. There is an elongate dorsal fin filament. All species have a deep, laterally compressed body with a continuous dorsal fin and distinctive rounded anal fin. The mouth is small, terminal, and protrusible with small brushlike teeth.
Length to 21 cm (8 inches)
DISTRIBUTION/HABITAT: Indo-Pacific; widely distributed from the Red Sea and the east coast of Africa to Hawaii on outer reef slopes, 15–210 m (50-690 ft.) in the tropics typically in cool upwelling water.
DIET IN THE WILD: Zooplankton.

CONSERVATION: IUCN Least Concern (LC)
REMARKS: Form large schools, and also occur in small groups or solitary. Their elongate dorsal fin filament, gives this group of fishes their “bannerfish” moniker; is the fourth dorsal spine. Often called the “false” Moorish Idol for its markings similar to the Steinhart’s iconic species; however, the flowing dorsal fin and larger size of the Idol are distinctive differentiations.
