Common name: Hongkong butterflyfish

General information

The Peacock Butterflyfish, scientifically known as Chaetodon wiebeli, is a vibrant and attractive species that adds a splash of color to any marine aquarium. This species is known for its striking appearance, characterized by a white body with a complex pattern of black lines and a distinctive 'eye spot' on the dorsal fin, which may help to confuse predators. The Peacock Butterflyfish is relatively rare in the aquarium trade compared to other butterflyfish species, making it a prized addition for enthusiasts.

Care

Chaetodon wiebeli requires a well-established aquarium with plenty of live rock for grazing and hiding. They are not considered reef-safe as they may nip at coral polyps and sessile invertebrates. A varied diet of meaty foods, including marine fish, crustacean flesh, and mysis shrimp, is essential for their health. They can be shy and may need a peaceful environment to thrive, so tankmates should be chosen carefully.

Reproduction

In the wild, Peacock Butterflyfish form monogamous pairs during the breeding season. They are pelagic spawners, releasing eggs and sperm into the water column where fertilization occurs. The eggs are buoyant and dispersed by currents. Breeding them in captivity is challenging and rarely achieved by hobbyists.

Habitat

The natural habitat of Chaetodon wiebeli includes coral reefs and lagoons in the Western Pacific, from the Philippines to northern Australia. They are typically found at depths ranging from 3 to 30 meters, where they swim in pairs or small groups.
