The Chrysurus Angelfish (Pomacanthus chrysurus) is an eye-catching marine species admired for its intricate patterns and vibrant hues. Belonging to the Pomacanthidae family, this angelfish is an attractive choice for aquarists familiar with the care and requirements of marine angelfish.
Appearance: Adult Chrysurus Angelfish are primarily yellow with blue accents. Their body features a series of curved blue lines, and they have a vibrant blue edge on their dorsal and anal fins. The tail fin showcases a unique pattern, with yellow on the base transitioning to blue with a central yellow spot. Juveniles, in contrast, have a different coloration, exhibiting vertical white bars on a dark background.
Distribution & Habitat: Native to the Western Indian Ocean, Chrysurus Angelfish are typically found in coral reef environments and coastal lagoons.
Aquarium Care:
- Tank Size: Due to their potential size, reaching up to about 15 inches (38 cm) in length, they require a spacious aquarium. A tank of at least 180 gallons (680 liters) is recommended.
- Diet: Chrysurus Angelfish are omnivores. Their natural diet includes sponges, algae, and tiny invertebrates. In captivity, they should be fed a varied diet that comprises marine-based algae, spirulina, mysis shrimp, angelfish preparations, and other suitable marine foods.
- Tank Mates: They can be semi-aggressive, especially towards other angelfish or similarly shaped species. They’re best housed with other peaceful to semi-aggressive fish. Avoid keeping them with aggressive species or others that might bully or compete with them for food.
- Environment: A reef-like setting with ample live rocks, caves, and hiding spots is ideal. This promotes natural behaviors and offers places for retreat.
- Water Parameters: Maintain marine conditions – salinity between 1.023-1.025 specific gravity, temperatures of 74-78°F (23-25.5°C), and pH levels of 8.1-8.4.
- Health: As with other marine species, they can be susceptible to various diseases. Regular observations for signs of distress or illness, quarantine for new tank additions, and maintaining pristine water conditions can help keep them healthy.
Conclusion: The Chrysurus Angelfish is a visually striking species that can be a centerpiece in a large marine aquarium. However, they require dedicated care, a balanced diet, and a stress-free environment to truly flourish in captivity. For aquarists willing to meet their needs, this angelfish offers a unique and vibrant presence in the marine tank.
