Common name: St. Helena butterflyfish

General information

The St. Helena Butterflyfish, Chaetodon sanctaehelenae, is a rare and beautiful species endemic to the South Atlantic Ocean, particularly around the remote island of St. Helena. This fish is known for its striking coloration, with a yellow body, black vertical bands, and a distinctive black spot on the rear of the dorsal fin. Due to its limited distribution, it is not commonly found in the aquarium trade, but it is highly prized by advanced hobbyists who manage to acquire one.

Care

Caring for the St. Helena Butterflyfish can be challenging due to its specific dietary and environmental needs. In the wild, they feed primarily on coral polyps and benthic invertebrates, so a varied diet including live, frozen, and possibly vitamin-enriched foods is essential to maintain their health in captivity. They require a large, mature aquarium with plenty of live rock for grazing and hiding.

Reproduction

Little is known about the reproductive habits of the St. Helena Butterflyfish in the wild or in captivity. However, like many butterflyfish, they are likely to form monogamous pairs and engage in elaborate courtship displays. Breeding them in home aquariums is considered very difficult and is rarely achieved.

Habitat

The St. Helena Butterflyfish is found in rocky reefs and slopes, often in relatively shallow waters. They are associated with healthy coral growth, which provides both food and shelter. Their natural habitat is characterized by clear, warm waters with strong currents, which should be replicated as closely as possible in the home aquarium for the best chance of success.
