Common name: Queensland Yellowtail Angelfish

General Information

The Queensland Yellowtail Angelfish, scientifically known as Chaetodontoplus meredithi, is a stunning marine fish that captivates aquarists with its striking appearance and unique charm. This species is native to the waters of the Great Barrier Reef and the Coral Sea, where it inhabits coral-rich lagoons and outer reef slopes. Its vibrant coloration and graceful swimming patterns make it a prized addition to large home aquariums.

Commonly called the Queensland Yellowtail Angelfish due to its distinctive yellow tail, or Meredith's Angelfish, Chaetodontoplus meredithi is named in honor of the Australian aquarist and dive instructor John G. Meredith, who collected the species. It is a member of the Pomacanthidae family, known for their vibrant colors and intricate patterns.

The Queensland Yellowtail Angelfish is visually very similar to the closely related Chaetodontoplus personifer. However, the Queensland Yellowtail Angelfish can be distinguished by its vibrant yellow tail.

Care

Queensland Yellowtail Angelfish requires a spacious aquarium with plenty of live rock to provide hiding spots and grazing areas. They thrive in well-maintained systems with stable water parameters and moderate water flow. This species is best suited for experienced aquarists due to its specific care requirements and sensitivity to changes in water quality.

A tank of at least 500 liters is recommended to accommodate their active swimming behavior and territorial nature. Providing a varied diet and maintaining pristine water conditions are crucial for their health and longevity.

Diet and Feeding

In the wild, Queensland Yellowtail Angelfish are omnivorous, feeding on sponges, tunicates, and algae. In captivity, they should be offered a varied diet that includes high-quality angelfish preparations, mysis shrimp, and spirulina-based foods. Regular feeding of small portions throughout the day helps mimic their natural grazing behavior.

Behavior and Compatibility

Queensland Yellowtail Angelfish are generally peaceful but can exhibit territorial behavior, especially towards other angelfish. They are best kept as solitary individuals in a tank or with other non-aggressive species. Caution is advised when housing them with other angelfish or similarly shaped fish to prevent aggression.

Health and Common Issues

These angelfish are susceptible to common marine diseases such as ich and marine velvet. Quarantining new additions and maintaining excellent water quality are essential preventive measures. Regular observation for signs of stress or illness can help ensure early intervention and treatment.

Habitat

Queensland Yellowtail Angelfish are found in the tropical waters of the Western Pacific, particularly around the Great Barrier Reef and Coral Sea. They prefer coral-rich environments with plenty of hiding spots and access to open water for swimming. Their natural habitat features stable temperatures and moderate water flow, conditions that should be replicated in captivity to ensure their well-being.
