Common name: Eritrean butterflyfish

Scientific name: Chaetodon paucifasciatus Ahl, 1923

General information

The Eritrean Butterflyfish, scientifically known as Chaetodon paucifasciatus, is a striking species native to the Red Sea and Gulf of Aden. It is closely related to the more widespread Raccoon Butterflyfish but can be distinguished by its more limited distribution and unique coloration. This species is admired for its bold white and black bands and the distinctive 'crown' pattern on its head.

Care

In the aquarium, the Eritrean Butterflyfish requires a well-established, spacious tank with plenty of live rock for grazing and hiding. They are not considered reef-safe as they may nip at corals and sessile invertebrates. A varied diet of meaty foods, including mysis shrimp, brine shrimp, and quality marine flakes or pellets, is essential for their health.

Reproduction

Like many butterflyfish, Chaetodon paucifasciatus is believed to be a pelagic spawner, releasing eggs and sperm into the water column where fertilization occurs. The larvae are planktonic, drifting in the currents until they develop into juveniles and settle into the reef.

Habitat

The Eritrean Butterflyfish is typically found in coral-rich areas of lagoons and seaward reefs, often in pairs or small groups. They prefer clear waters and are usually observed at depths ranging from 3 to 20 meters. Their natural range is restricted to the Red Sea and Gulf of Aden, making them a geographically exclusive species.
