Common name: Oman butterflyfish

General information

The White-tailed Butterflyfish, Chaetodon dialeucos, is a relatively new species to science, having been described in 1979. It is known for its striking appearance, with a predominantly white body, black vertical bands, and a distinctive white tail. This species is not commonly found in the aquarium trade, primarily due to its rarity and the challenges associated with collecting it from its natural habitat.

Care

White-tailed Butterflyfish are considered challenging to keep in home aquariums due to their specialized dietary requirements. They primarily feed on coral polyps and benthic invertebrates in the wild, which can be difficult to replicate in captivity. Hobbyists who wish to keep this species should be experienced and willing to provide a varied diet that includes live foods and supplements to ensure proper nutrition.

Reproduction

There is limited information available on the reproductive habits of Chaetodon dialeucos in the wild or in captivity. Like other butterflyfish, they are likely to form monogamous pairs and engage in elaborate courtship displays. Spawning typically occurs with the release of eggs and sperm into the water column, where fertilization takes place.

Habitat

Chaetodon dialeucos is found in the Western Pacific, specifically around the Philippines and Indonesia. It inhabits coral-rich areas of lagoons and seaward reefs, usually at depths ranging from 3 to 20 meters. This species is often observed in pairs or small groups, swimming close to the reef structure.
