Common name: Clarion Angelfish

General Information

The Clarion Angelfish, scientifically known as Holacanthus clarionensis, is a strikingly beautiful marine fish known for its vibrant orange and blue coloration. This species is named after the Clarion Island, part of the Revillagigedo Islands in Mexico, where it is predominantly found. The Clarion Angelfish is highly sought after in the aquarium trade due to its vivid colors and rarity.

In the wild, the Clarion Angelfish plays a significant role in maintaining the health of coral reefs by controlling algae growth. In the aquarium hobby, it is prized for its aesthetic appeal and the challenge it presents to experienced aquarists. However, due to its limited natural range and the pressures of over-collection, it is important to ensure that any Clarion Angelfish purchased has been sourced responsibly.

Care

Caring for a Clarion Angelfish requires a well-established marine aquarium with plenty of live rock for grazing and hiding. These fish are best kept in larger tanks to accommodate their active swimming and territorial nature. A tank of at least 500 liters is recommended to provide ample space.

The aquarium should mimic their natural reef environment, with stable water conditions and a variety of hiding spots. Clarion Angelfish are known to be somewhat aggressive, especially towards other angelfish, so careful consideration should be given to tank mates.

Diet and Feeding

Clarion Angelfish are omnivorous, feeding on a diet that includes sponges, algae, and small invertebrates in the wild. In captivity, they should be offered a varied diet that includes high-quality marine angelfish preparations, spirulina, mysis shrimp, and other meaty foods.

Feeding should occur two to three times daily, with portions that can be consumed within a few minutes. This helps maintain their vibrant coloration and overall health.

Behavior and Compatibility

The Clarion Angelfish is known for its semi-aggressive temperament. It can be territorial, especially in smaller aquariums or when housed with similar species. It is generally best kept as a single specimen or in a large tank with other non-aggressive species.

While they are not considered reef-safe, as they may nip at corals and invertebrates, some hobbyists have had success keeping them in reef tanks with caution.

Reproduction

Breeding Clarion Angelfish in captivity is challenging and has rarely been achieved. They are known to form pairs, and successful breeding typically requires very specific conditions that mimic their natural environment.

Health and Common Issues

Clarion Angelfish can live for over 20 years in captivity with proper care. They are generally hardy but can be susceptible to common marine diseases such as ich and marine velvet. Maintaining high water quality and a balanced diet is crucial to their health.

When selecting a Clarion Angelfish, look for vibrant colors and active behavior, as these are indicators of good health.

Habitat

The Clarion Angelfish is native to the Eastern Pacific Ocean, specifically around the Revillagigedo Islands. They inhabit rocky reefs and are often found at depths ranging from 3 to 30 meters. The waters in this region are warm and nutrient-rich, providing an ideal environment for these colorful fish.

Conservation Status

The Clarion Angelfish is listed under CITES Appendix II, indicating that while it is not currently threatened with extinction, trade must be controlled to ensure its survival. Hobbyists should ensure they purchase from reputable sources that comply with international regulations to support conservation efforts.
