General Description
The Eritrean Butterflyfish, scientifically known as Chaetodon paucifasciatus, belongs to the Chaetodontidae family. These fish are part of a group known as a "complex" due to their striking resemblance to each other. They are recognized for their attractive patterns and colors and are closely related to angelfish but lack the spines on the sides of the head that angelfish possess.
Aquarium Suitability
The Eritrean Butterflyfish are suitable for aquariums with care, best kept in a well-established tank with at least 300 liters of water capacity. They are generally peaceful but may display aggression towards similar species, making it important to either keep them alone or in pairs. These fish require good hiding spots within live rocks and ample space for swimming.
Demands, Care, and Hardiness
With an average hardiness level, these fish prefer environments with water conditions that maintain a pH of 8.1-8.4, a specific gravity of 1.020-1.025, and a temperature range of 22.2-25.6 degrees Celsius. Eritrean Butterflyfish need a varied diet consisting of macroalgae, microalgae, small crustaceans, and zooplankton. They should be fed multiple times a day to ensure proper nutrition.
Reef Suitability
While these fish are compatible with some reef setups, they are generally considered not reef safe due to their tendency to nibble at clams, including Tridacna species, and their preference for eating tubeworms.
Aquarium Setup
When setting up an aquarium for Eritrean Butterflyfish, it is crucial to provide plenty of hiding places among live rocks. A well-maintained tank with algae-covered surfaces for grazing is recommended. It's essential to ensure there is enough algae for them to feed on; otherwise, supplement their diet with algae-rich foods like Spirulina.
Behaviour
Eritrean Butterflyfish are known to be shy and docile, making them vulnerable to more aggressive tankmates. They tend to ignore other fish and can coexist with their species if introduced simultaneously. However, caution is advised when housing them with similar species unless they are a mated pair.
Feeding and Diet
Their diet should consist of various food types, including large polyp stone coral (LPS), small polyp stone coral (SPS), and soft coral. These fish thrive on feeding on algae, zooplankton, and small invertebrates. Ensuring a well-rounded diet is essential for their health and well-being.
Dimorphism and Habitat Distribution
Dimorphism information regarding Eritrean Butterflyfish is not provided. These fish are found in the Western Indian Ocean specifically in the Red Sea and the Gulf of Aden. They are part of the Xanthurus complex, which includes species such as Chaetodon mertensii and Chaetodon madagaskariensis, with distinguishing characteristics related to their orange coloration.
