Common name: Phantom bannerfish

General information

The Heniochus pleurotaenia, commonly known as the Pyramid Butterflyfish or Pennant Coralfish, is a striking marine fish that adds both beauty and intrigue to a saltwater aquarium. Its most distinctive feature is the elongated white dorsal filament that extends from its back, resembling a pennant. The body is primarily white with two broad black vertical bands and a yellow area near the tail fin.

This species is not as commonly kept as some other butterflyfish due to its specific dietary requirements and larger size. It is also known for its peaceful temperament, making it a suitable companion for many other non-aggressive fish species in a community tank.

Care

The Pyramid Butterflyfish requires a spacious tank with plenty of swimming space and rockwork to provide hiding places. It is essential to maintain high water quality and stable conditions, as this species can be sensitive to fluctuations in water parameters.

Feeding can be challenging, as Heniochus pleurotaenia has a preference for live foods and may not readily accept prepared diets. A varied diet including mysis shrimp, plankton, and other meaty foods, as well as some vegetable matter, can help ensure proper nutrition.

Reproduction

Breeding Heniochus pleurotaenia in captivity is rare and challenging. In the wild, they are pelagic spawners, releasing eggs and sperm into the water column where fertilization occurs. The larvae are planktonic and go through several developmental stages before settling down and transforming into juveniles.

Habitat

Heniochus pleurotaenia is found in the Indo-Pacific region, from the Red Sea and East Africa to the Hawaiian Islands and Japan. It typically inhabits coral reefs and lagoons, often in pairs or small groups, and can be found at depths ranging from shallow waters to about 25 meters.
