Common name: Cocos-Keeling Angelfish

General information

The Cocos-Keeling Angelfish, scientifically known as Chaetodontoplus poliourus, is a stunning marine fish that adds a splash of color and grace to any saltwater aquarium. This species is named after its native habitat around the Cocos (Keeling) Islands in the Indian Ocean. It is characterized by its deep blue body, accented with vibrant yellow on the edges of its dorsal and anal fins, and a striking yellow face.

Care

Caring for the Cocos-Keeling Angelfish requires a well-established aquarium with plenty of live rock for grazing and hiding. This species can grow up to 7 inches in length, so a larger tank is necessary to provide ample swimming space. They are omnivores, feeding on a variety of foods including marine algae, spirulina, mysis shrimp, and other meaty foods, as well as high-quality angelfish preparations that contain sponges.

Reproduction

In the wild, Chaetodontoplus poliourus is oviparous, with pairs forming during breeding. They engage in a courtship dance before spawning, releasing eggs and sperm into the water column. The eggs are pelagic, drifting with the currents until hatching. Breeding in captivity is rare and challenging, requiring specific conditions and expert care.

Habitat

The natural habitat of the Cocos-Keeling Angelfish is the coral-rich areas and clear lagoons of the Cocos (Keeling) Islands. They are typically found at depths ranging from shallow waters to about 25 meters. This species is relatively rare in the aquarium trade, making it a prized specimen for dedicated marine aquarists.
