Common name: Singular bannerfish

General information

The Singular Bannerfish, Heniochus singularius, is a striking marine fish known for its elegant white body with two broad black vertical bands and a long, white dorsal filament. It is often mistaken for the more famous Moorish Idol due to its similar appearance but is generally easier to care for in captivity. This species is a member of the Butterflyfish family (Chaetodontidae) and is appreciated for its graceful swimming behavior and unique body shape.

Care

Singular Bannerfish are moderately easy to care for, making them suitable for intermediate aquarists. They require a well-established aquarium with plenty of swimming space and stable water conditions. These fish are not as aggressive as some other marine species, but they can be territorial with their own kind. It's best to keep them singly or in a mated pair. They accept a variety of foods including mysis shrimp, brine shrimp, and high-quality marine flake and pellet foods.

Reproduction

In the wild, Singular Bannerfish form monogamous pairs during the breeding season. They are pelagic spawners, releasing their eggs and sperm into the water column where fertilization occurs. The eggs are then left to drift with the currents. Breeding them in captivity is challenging and not commonly done by hobbyists.

Habitat

Singular Bannerfish are found in the Indo-Pacific region, from the Red Sea and East Africa to the Hawaiian Islands, north to southern Japan, and south to New Caledonia and the Tuamotu Archipelago. They inhabit coral reefs and lagoons, often seen swimming in pairs or small groups. They prefer depths ranging from 1 to 75 meters.
