General Description
The Spot-nape butterflyfish (Chaetodon oxycephalus) belongs to the Chaetodontidae family and is known for its attractive patterns and colors. These fish lack the spines on each side of the head, which distinguishes them from Angelfish. In the aquarium trade, some species in the Chaetodon genus are classified in a complex due to their similarities, but it's crucial to differentiate them, especially concerning their specific needs and origins.
Aquarium Suitability
The Spot-nape butterflyfish requires experience, preparation, and extra care in a home aquarium setting. Due to their dietary preferences, including large polyp stone corals (LPS) and soft corals, maintaining these fish can be challenging, and they are not considered reef safe due to their diet and potential aggression.
Demands, Care, and Hardiness
Spot-nape butterflyfish have average hardiness and necessitate several feedings per day, especially when newly introduced to the tank. Ensuring a varied diet is crucial for their well-being. They thrive in well-established aquariums with ample hiding places among live rocks and algae-rich environments.
Reef Suitability
These fish are not considered reef safe due to their tendency to feed on corals, particularly LPS and soft corals. They may also exhibit aggression towards similar species or those that compete for food sources.
Aquarium Setup
Maintaining a healthy Spot-nape butterflyfish requires a minimum tank size of 600 liters. The aquarium should provide plenty of space for swimming and include live rocks for hiding. It is essential to have a well-established tank with algae for grazing or supplement their diet with algae-rich foods like Spirulina.
Behaviour
Spot-nape butterflyfish are generally peaceful towards other fish but may display aggression towards similar species. They require hiding spots and prefer swimming in open spaces within the aquarium.
Feeding and Diet
These fish predominantly feed on coral polyps, making them challenging to sustain in captivity. Offering alternative food sources is essential, such as living corals, mussels, and zooplankton. Ensuring a varied diet that mimics their natural feeding behavior is crucial for their survival.
Dimorphism
No information provided.
Habitat and Distribution
Spot-nape butterflyfish are found in the Indo-Pacific region, ranging from Sri Lanka to Queensland and north to the Philippines. They inhabit areas with large polyp stone corals, soft corals, anemones, tubeworms, and other small invertebrates, reflecting their dietary preferences and habitat choices.
