The Queen Angelfish (Holacanthus ciliaris) is a stunning and vibrantly colored marine fish that inhabits the reefs of the Western Atlantic, ranging from Florida to Brazil. Its majestic appearance and vibrant colors make it a favorite among marine aquarium enthusiasts. However, its care can be challenging, and potential keepers should be familiar with its requirements and natural behavior.
Appearance: The Queen Angelfish is primarily blue with yellow rims on its scales, giving it a shimmering appearance. It has a dark ringed spot with blue borders on its forehead, which resembles a crown, hence the name “Queen.” Additionally, the dorsal and pelvic fins are elongated, and a yellow tail completes its striking appearance. As juveniles, their coloring is more muted with blue bodies and vertical yellow bars.
Habitat: They’re commonly found around coral reefs and rocky outcrops, ranging in depths from shallow waters to about 70 meters deep.
Aquarium Care:
- Tank Size: Given their potential size of up to 18 inches in the wild (though usually smaller in captivity), a minimum tank size of 250 gallons (945 liters) is recommended. This provides adequate space for the fish to swim and establish territories.
- Diet: Queen Angelfish are omnivores. In the wild, their diet includes sponges, algae, corals, tunicates, and plankton. In captivity, they should be provided with a varied diet that includes marine algae, high-quality angelfish preparations, mysis or brine shrimp, and other meaty items.
- Tank Mates: They can be territorial, especially towards other angelfish or similar-looking species. Choose tank mates that are not overly aggressive but can stand up to the assertiveness of the Queen Angelfish. Avoid keeping with small ornamental shrimp, as they might become snacks.
- Environment: A well-decorated aquarium with plenty of hiding spots and live rock is ideal. They need spaces where they can retreat and establish territories.
- Water Parameters: Maintain typical marine conditions – salinity of 1.023-1.025 specific gravity, temperatures of 74-78°F (23-25.5°C), and pH levels between 8.1-8.4.
- Health: While they are hardy, like all marine species, they can be prone to typical saltwater fish diseases. Regular observation, maintaining clean water, and a proper quarantine process for new tank additions can aid in preventing many health issues.
Conclusion: The Queen Angelfish is a magnificent marine fish that can be the centerpiece of a large marine aquarium. Their care requires some expertise and dedication, given their specific dietary and environmental needs. With the right care, they can be a long-lived and dazzling addition to a suitable marine setup.
