Common name: Blue Angelfish

General Information

The Blue Angelfish, scientifically known as Holacanthus bermudensis, is a strikingly beautiful species that captivates aquarists with its vibrant blue and yellow coloration as a juvenile. This species is native to the western Atlantic Ocean, particularly around Bermuda, the Bahamas, and the Gulf of Mexico. Known for its bold appearance and regal demeanor, the Blue Angelfish is a prized specimen in the marine aquarium trade.

While not as commonly kept as some other angelfish species, the Blue Angelfish is appreciated for its aesthetic appeal and the challenge it presents to experienced hobbyists. Its vivid colors and large size make it a centerpiece in any large marine aquarium.

Care

Caring for a Blue Angelfish requires a well-established aquarium with plenty of swimming space and hiding spots. These fish are best suited for large tanks with a minimum volume of 500 liters (about 130 gallons) to accommodate their size and territorial nature. The tank should be equipped with live rock formations that provide both shelter and grazing opportunities.

Blue Angelfish thrive in stable water conditions. They require efficient filtration and regular water changes to maintain optimal water quality.

Diet and Feeding

In the wild, Blue Angelfish are omnivorous, feeding on a variety of sponges, algae, and small invertebrates. In captivity, they should be offered a diverse diet that includes high-quality marine angelfish preparations, spirulina, mysis shrimp, and finely chopped seafood. Supplementing their diet with sponge-based foods is essential to meet their nutritional needs.

Feed Blue Angelfish two to three times daily, ensuring they receive a balanced diet to maintain their vibrant coloration and overall health.

Behavior and Compatibility

Blue Angelfish are known for their semi-aggressive temperament, particularly towards other angelfish and similarly sized tank mates. They are best kept as the sole angelfish in the aquarium to prevent territorial disputes. However, they can coexist with other large, non-aggressive fish species.

These angelfish are not considered reef-safe, as they may nip at corals and sessile invertebrates. Caution is advised when housing them in a reef environment.

Reproduction

Breeding Blue Angelfish in captivity is challenging and rarely achieved. They are pelagic spawners, releasing eggs and sperm into the water column. Successful breeding requires specific environmental conditions and a dedicated breeding setup.

Health and Common Issues

Blue Angelfish can live up to 15 years in captivity with proper care. Maintaining water quality and providing a balanced diet are crucial to their longevity. They are susceptible to common marine diseases such as ich and marine velvet, so quarantine new additions and monitor for signs of illness.

Habitat

The natural habitat of the Blue Angelfish includes coral reefs and rocky areas where they can find shelter and food. They are typically found at depths ranging from 2 to 90 meters (6 to 300 feet), thriving in warm, tropical waters.
