Common name: Zanzibar butterflyfish

General information

The Zanzibar Butterflyfish, scientifically known as Chaetodon zanzibarensis, is a striking species admired for its vibrant coloration and patterns. This species is characterized by its deep yellow body, adorned with a series of vertical black stripes and a prominent black eye band. The dorsal and anal fins have a delicate appearance with soft, trailing edges that add to its graceful demeanor.

While not as common as some other butterflyfish in the aquarium trade, the Zanzibar Butterflyfish can be a captivating addition to a well-established marine aquarium. However, they are best suited for aquarists with some experience due to their specific dietary and environmental needs.

Care

Zanzibar Butterflyfish require a tank with plenty of live rock formations to provide both shelter and foraging opportunities. They are known to be somewhat delicate when it comes to water quality, necessitating stable and pristine conditions. A varied diet is crucial for their health, consisting of a mix of meaty foods, algae, and marine-based flakes or pellets.

It's important to note that this species may nip at stony and soft corals, as well as anemones, making them less suitable for a reef tank with a variety of corals. They are best kept in a fish-only or fish-only-with-live-rock (FOWLR) setup.

Reproduction

In the wild, Zanzibar Butterflyfish form monogamous pairs during the breeding season. They are broadcast spawners, releasing eggs and sperm into the water column where fertilization occurs. Raising the larvae in captivity is challenging and not commonly attempted by hobbyists.

Habitat

Native to the Western Indian Ocean, the Zanzibar Butterflyfish is found in coral-rich areas and clear lagoons, typically at depths ranging from the surface to about 20 meters. They are often observed in pairs or small groups, navigating through the complex structures of the reef.
