Chaetodon xanthocephalus

Datasheet

General Description

The Yellowhead Butterflyfish (Chaetodon xanthocephalus) belongs to the Chaetodontidae family and is part of the Chaetodon genus complex. These fish are visually appealing, with attractive patterns and colors that set them apart. They are characterized by a vibrant yellow head and are known to occasionally nibble at clams, particularly those of the Tridacna species. In terms of diet, they primarily feed on large polyp stony corals (LPS) and soft corals.

Aquarium Suitability and Demands

The Yellowhead Butterflyfish is considered suitable for aquariums, but with care. They have average hardiness and require a minimum tank size of 500 liters. Frequent feeding, hiding places among live rocks, a varied diet, and plenty of space for swimming are essential for their well-being. Additionally, they thrive in well-established aquariums with algae for grazing.

Care and Hardiness

Yellowhead Butterflyfish have an average level of hardiness and demand a well-maintained environment for their optimal health. They require frequent feeding, good hiding spots, a varied diet, and ample swimming space to flourish. Ensuring a stable aquarium with sufficient algae for grazing is crucial for their well-being.

Reef Suitability

Yellowhead Butterflyfish are not considered reef-safe due to their tendency to nibble at clams, including Tridacna species. Their diet primarily consists of corals and other invertebrates, making them incompatible with a reef environment.

Aquarium Setup

When setting up an aquarium for Yellowhead Butterflyfish, it is essential to provide plenty of hiding places among live rocks. The tank should be well-established with adequate algae growth for grazing. Maintaining stable water conditions with a pH of 8.1-8.4, a specific gravity of 1.020-1.025, and a temperature range of 22.2-25.6°C is crucial for their overall health.

Behaviour

The temperament and social behavior of Yellowhead Butterflyfish are not specified. However, it is noted that they generally ignore other fish and are peaceful towards tank mates. They may exhibit territorial behavior, especially if kept in pairs or groups.

Feeding and Diet

Yellowhead Butterflyfish have a varied diet that includes larger crustaceans, microalgae like Spirulina, other invertebrates, small crustaceans, and zooplankton. It is essential to feed them several times a day, especially when they are newly introduced to the aquarium. Providing a diet rich in live SPS or LPS corals can help mimic their natural feeding behavior.

Habitat and Distribution

Yellowhead Butterflyfish are primarily found in the Western Indian Ocean, ranging from East Africa to Sri Lanka and the Maldives. They inhabit reef areas with a diverse range of corals, invertebrates, and algae that form an integral part of their diet.
