General information

The Robust Butterflyfish, scientifically known as Chaetodon robustus, is a striking species that is not commonly found in the aquarium trade. This species is known for its resilience and adaptability to various reef environments. It has a distinctive appearance with a silver-white base color and a series of vertical black stripes across its body, complemented by a yellow dorsal fin.

Care

Robust Butterflyfish are considered moderately difficult to care for due to their specific dietary requirements. In the wild, they primarily feed on coral polyps and benthic invertebrates. In captivity, they require a varied diet that includes meaty foods such as mysis shrimp, brine shrimp, and high-quality marine flakes and pellets that are formulated for marine fish. It is crucial to provide a well-established aquarium with plenty of live rock for grazing and hiding.

Reproduction

Little is known about the reproductive habits of Chaetodon robustus in the wild or in captivity. Like many butterflyfish, they are likely to form monogamous pairs during the breeding season. Breeding in home aquariums is rare and not well documented.

Habitat

Chaetodon robustus is found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific Ocean. They inhabit coral reefs and lagoons, often seen at depths ranging from 1 to 30 meters. They are typically found in pairs or small groups, navigating through complex reef structures.
