Common name: Eibli Angelfish

General Information

The Eibli Angelfish or Blacktail Angelfish, scientifically known as Centropyge eibli, is a captivating species that has gained popularity among marine aquarium enthusiasts. Known for its striking appearance, the Eibli Angelfish features a silvery-blue body adorned with vertical orange stripes and a distinctive black tail edged with a vibrant blue hue. This species is often sought after for its unique beauty and relatively manageable care requirements.

While not as widely recognized as some other angelfish species, the Eibli Angelfish holds its own in the aquarium trade. It is appreciated for its adaptability and the splash of color it brings to a reef tank. However, aquarists should be aware of its potential to nip at corals, making it a "reef-safe with caution" species.

Care

The Eibli Angelfish is considered moderately difficult to care for, making it suitable for aquarists with some experience. It thrives in well-established aquariums that mimic its natural reef environment. A tank of at least 200 liters is recommended to provide ample swimming space and territories. The setup should include plenty of live rock for grazing and hiding spots, as this species enjoys exploring crevices and caves.

Maintaining stable water conditions is crucial for the health of the Eibli Angelfish. Regular water changes and monitoring of parameters like pH, salinity, and temperature are essential.

Diet and Feeding

Eibli Angelfish are omnivores, requiring a varied diet to thrive. In the wild, they feed on algae, small invertebrates, and detritus. In captivity, their diet should include high-quality marine angelfish preparations, spirulina, mysis shrimp, and finely chopped seafood. Offering a mix of frozen, live, and flake foods can help meet their nutritional needs.

Feeding should occur two to three times daily, with portions that the fish can consume within a few minutes. Overfeeding can lead to poor water quality, so it's important to monitor their intake.

Behavior and Compatibility

The Eibli Angelfish is generally peaceful but can exhibit semi-aggressive behavior, particularly towards other angelfish or similarly shaped species. It is best housed singly or in a well-planned community tank with other peaceful species.

Due to its potential to nip at corals and clams, caution is advised when adding it to a reef tank. Providing ample grazing opportunities and a varied diet can help mitigate this behavior.

Reproduction

Breeding Eibli Angelfish in captivity is challenging and not commonly achieved. They are egg scatterers, releasing eggs into the water column, where they are fertilized. Specific conditions, such as dim lighting and a well-established environment, may encourage spawning behavior, but success is rare.

Health and Common Issues

Eibli Angelfish are relatively hardy but can be susceptible to common marine diseases such as ich and marine velvet. Quarantining new additions and maintaining excellent water quality are key preventive measures.

When selecting an Eibli Angelfish, look for individuals with vibrant colors and active behavior. Avoid fish with visible signs of stress or disease, such as clamped fins or rapid breathing.

Habitat

Native to the Indo-Pacific region, the Eibli Angelfish is typically found in lagoons and outer reef slopes. They inhabit areas with abundant coral and rock formations, providing plenty of hiding spots and grazing opportunities. In the wild, they are often seen at depths ranging from 1 to 25 meters.

Creating a similar environment in captivity, with plenty of live rock and stable water conditions, will support their health and well-being.
