Common name: Pennant bannerfish

General information

The Pennant Coralfish, also known as the Longfin Bannerfish, is a striking marine fish that is popular among aquarists for its elegant appearance. Heniochus chrysostomus is characterized by its long, white dorsal filament, black, white, and yellow body markings, and peaceful demeanor. This species is often confused with its close relative, the Heniochus acuminatus, but can be distinguished by the shape of its black dorsal blotch and the yellow area on its snout.

Care

Pennant Coralfish are considered moderate to care for. They require a large tank with plenty of swimming space and stable water conditions. These fish are not aggressive and can be kept with a variety of other peaceful species. They are omnivores and should be fed a varied diet of meaty foods and vegetable matter to maintain their health and coloration.

Reproduction

In the wild, Heniochus chrysostomus forms pairs during the breeding season. Little is known about their breeding habits in home aquariums, as they are not commonly bred in captivity. However, providing a stress-free environment with plenty of hiding places may encourage spawning behavior.

Habitat

The Pennant Coralfish is found in the Indo-Pacific region, from the Red Sea and East Africa to the Hawaiian Islands and Japan. They typically inhabit coral reefs and lagoons, often swimming in pairs or small groups. They can be found at depths ranging from 2 to 75 meters.
