Common name: Queen Angelfish

General Information

The Queen Angelfish, scientifically known as Holacanthus ciliaris, is a stunning marine fish admired for its vibrant colors and regal appearance. Its striking blue body adorned with yellow accents and a distinctive "crown" on its forehead make it a standout in any aquarium. This species is native to the warm waters of the western Atlantic Ocean, from Florida to Brazil, including the Gulf of Mexico and the Caribbean Sea.

Queen Angelfish are highly sought after in the aquarium trade due to their beauty and unique coloration. They play an important role in marine ecosystems, often seen grazing on sponges and algae, which helps maintain the balance of coral reef environments. However, their size and specific care requirements make them more suitable for experienced aquarists.

Care

Queen Angelfish require a spacious aquarium with plenty of live rock for grazing and hiding. They thrive in well-established tanks that mimic their natural reef habitat. A tank size of at least 500 liters (130 gallons) is recommended to accommodate their active swimming behavior and territorial nature.

These angelfish prefer stable water conditions. Good water quality and regular maintenance are crucial for their health and well-being.

Diet and Feeding

In the wild, Queen Angelfish are omnivorous, feeding on sponges, algae, and small invertebrates. In captivity, they should be offered a varied diet that includes high-quality marine angelfish preparations, along with fresh or frozen foods like mysis shrimp, brine shrimp, and chopped seafood.

Feeding should occur 2-3 times daily, with portions that they can consume within a few minutes. A diet rich in marine-based vitamins and supplements will help maintain their vibrant coloration and overall health.

Behavior and Compatibility

Queen Angelfish are known for their semi-aggressive temperament, particularly towards other angelfish and similar species. They establish territories within the aquarium and may show aggression towards tank mates that invade their space.

They are best kept with other semi-aggressive or larger, peaceful fish that can hold their own. Avoid housing them with smaller, more timid species that may be bullied.

Reproduction

Breeding Queen Angelfish in captivity is challenging and rarely achieved. They are pelagic spawners, releasing eggs into the water column, where they drift with the currents. Successful breeding requires specific conditions that are difficult to replicate in home aquariums.

Health and Common Issues

Queen Angelfish can live up to 15 years in captivity with proper care. Maintaining optimal water quality, a balanced diet, and regular health checks are essential to prevent common issues like ich and marine velvet.

When selecting a Queen Angelfish, look for individuals with bright colors, clear eyes, and smooth fins. Avoid fish that appear lethargic or have visible signs of disease.

Habitat

Queen Angelfish are found in coral reefs and rocky areas, often near sponges, at depths of 1-70 meters (3-230 feet). They are distributed throughout the western Atlantic, including the Caribbean Sea, Gulf of Mexico, and the coastlines of Florida and Brazil.

They prefer warm, clear waters with abundant coral and sponge growth, providing both food and shelter.
