Common name: Blackear Angelfish
General Information
The Blackear Angelfish, scientifically known as Centropyge hotumatua, is a captivating species within the marine aquarium trade. Known for its striking appearance, this angelfish is characterized by a predominantly dark blue and orange body adorned with a distinctive black spot behind the eyes, giving it the "blackear" moniker. It is a relatively rare find in home aquariums due to its limited distribution and collection challenges.
In the wild, the Blackear Angelfish is found in the central Pacific Ocean, particularly around the Society Islands and other parts of French Polynesia. This species is not only admired for its beauty but also for its relatively peaceful nature compared to other angelfish.

Care
Caring for the Blackear Angelfish requires attention to detail, particularly regarding its environment. These fish thrive in well-established aquariums that mimic their natural coral reef habitats. A tank with ample live rock for grazing and hiding is essential. They are best suited for aquariums of at least 200 liters, providing them with enough space to swim and explore.
Diet and Feeding
The Blackear Angelfish is an omnivore, feeding on a diet that includes algae, small crustaceans, and detritus in the wild. In captivity, they should be offered a varied diet that includes high-quality angelfish preparations, spirulina, mysis shrimp, and marine algae. Feeding small amounts several times a day can help keep them healthy and vibrant.
Behavior and Compatibility
Blackear Angelfish are generally peaceful but can exhibit territorial behavior, especially towards other dwarf angelfish. They are best kept singly or as a pair in larger tanks to avoid aggression. They can coexist with a variety of other peaceful fish species, making them a good addition to a community tank.
Reproduction
Breeding the Blackear Angelfish in captivity is challenging and not commonly achieved. Like many marine species, they exhibit complex mating behaviors and require specific conditions to spawn. Successful breeding typically involves a dedicated effort to simulate their natural environment and provide optimal water conditions.
Health and Common Issues
While generally hardy, the Blackear Angelfish can be susceptible to common marine diseases such as ich and marine velvet. Maintaining excellent water quality, a balanced diet, and regular monitoring for signs of stress or illness are crucial for their well-being.
Habitat
In their natural habitat, Blackear Angelfish are found in coral-rich areas of lagoons and outer reef slopes at depths ranging from 5 to 30 meters. They thrive in stable, warm water conditions with plenty of hiding spots and grazing areas provided by live rock.
