Common name: Triangle butterflyfish

General information

The Triangle Butterflyfish, scientifically known as Chaetodon triangulum, is a striking species popular among marine aquarists. Its body is primarily white with a complex pattern of black lines forming a unique triangular shape, hence its common name. This species is not as commonly kept as some other butterflyfish due to its specific dietary requirements.

Care

Triangle Butterflyfish are considered moderate to care for. They require a well-established aquarium with plenty of live rock for grazing and hiding. They are known to be picky eaters, often preferring live foods or frozen preparations that include sponges and tunicates. It is crucial to provide a varied diet to ensure their nutritional needs are met.

Reproduction

In the wild, Triangle Butterflyfish are pelagic spawners, releasing eggs and sperm into the water column where fertilization occurs. The larvae are planktonic before settling down and transforming into juveniles. Breeding them in captivity is challenging and not commonly done by hobbyists.

Habitat

Chaetodon triangulum is found in the Indo-Pacific region, from the eastern coast of Africa to the western Pacific Ocean. They inhabit coral reefs and are often observed in pairs or small groups. They prefer clear waters and are typically found at depths ranging from shallow lagoons to about 20 meters.

Due to their specific feeding habits and the need for a mature aquarium, the Triangle Butterflyfish is best suited for experienced aquarists who can cater to their needs.
