Common name: Pyramid butterflyfish

General information

The Pyramid Butterflyfish, scientifically known as Hemitaurichthys polylepis, is a striking species popular among aquarists for its unique coloration and peaceful demeanor. This species is characterized by its white body with a black pyramid-shaped pattern on the sides and a yellow to orange back. It is a member of the family Chaetodontidae, which includes all butterflyfish.

In the wild, Pyramid Butterflyfish are often found in large schools, swimming in the open water above coral reefs where they feed predominantly on plankton. This schooling behavior is not only a spectacular sight for divers but also an interesting characteristic for aquarists who wish to replicate natural behaviors in their tanks.

Care

Pyramid Butterflyfish are considered moderate to care for. They require a well-established aquarium with plenty of swimming space and stable water conditions. A diet of varied foods, including marine flakes, frozen and live foods such as mysis shrimp and plankton, is essential for maintaining their health and vibrant coloration. It is recommended to keep them in groups if the tank size permits, as they are naturally schooling fish.

Reproduction

Breeding Pyramid Butterflyfish in captivity is quite challenging and rarely achieved. In the wild, 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 until hatching.

Habitat

Hemitaurichthys polylepis is native to the Indo-Pacific region, commonly found from the Red Sea and East Africa to the Hawaiian, Marquesan, and Ducie islands, north to southern Japan, south to Lord Howe and Rapa islands. They inhabit clear, current-swept terraces of seaward reefs, typically at depths of 3 to 60 meters.
