Common name: Ballina Angelfish

General Information

The Ballina Angelfish, scientifically known as Chaetodontoplus ballinae, is a rare and striking species that captivates aquarists with its unique beauty. This elusive angelfish is named after the town of Ballina in New South Wales, Australia, where it was first discovered. Its rarity in the wild and in the aquarium trade makes it a prized possession for dedicated marine enthusiasts.

With its pearly-white body adorned with a distinct black band and yellow accents, the Ballina Angelfish stands out in any marine aquarium. Its distinct coloration and pattern make it easily recognizable, even among other angelfish species. However, due to its scarcity, it is often confused with other members of the Chaetodontoplus genus, such as the Chaetodontoplus duboulayi, which shares a similar habitat.

Care

Caring for the Ballina Angelfish requires a well-maintained marine environment that mimics its natural habitat. This species thrives in aquariums with plenty of live rock for grazing and hiding, as well as open swimming spaces. A tank of at least 500 liters is recommended to accommodate its active nature and territorial behavior.

The Ballina Angelfish prefers stable water conditions with a temperature range of 24-28°C. It is sensitive to poor water quality, so regular monitoring and maintenance are essential. Providing a varied diet rich in marine algae, sponges, and high-quality angelfish preparations will ensure its health and vibrant coloration.

Diet and Feeding

In the wild, the Ballina Angelfish feeds on a diet of sponges, tunicates, and algae. In captivity, it requires a varied diet that replicates its natural feeding habits. Offer a mix of frozen and live foods, including mysis shrimp, brine shrimp, and marine algae. Specialized angelfish pellets and flakes can also be included to provide balanced nutrition.

Feed the Ballina Angelfish two to three times daily, ensuring that it receives enough food to maintain its energy levels and vibrant colors. Monitor its feeding habits and adjust portions as needed to prevent overfeeding and maintain water quality.

Behavior and Compatibility

The Ballina Angelfish is known for its semi-aggressive temperament, particularly towards other angelfish and similar species. It is best kept as a solitary specimen or in a well-planned community tank with other non-aggressive species. Providing ample hiding spaces and territories can help reduce stress and aggression.

While not considered reef-safe, the Ballina Angelfish may occasionally nip at coral polyps and sessile invertebrates. Caution is advised when housing it in a reef aquarium, and regular observation is necessary to ensure compatibility with other tank inhabitants.

Reproduction

Breeding the Ballina Angelfish in captivity is a challenging endeavor that has not been widely documented. Like many marine angelfish, they are likely protogynous hermaphrodites, with the ability to change sex based on social dynamics. Creating a conducive breeding environment with stable water conditions and a balanced diet is essential for any potential breeding attempts.

Health and Common Issues

The Ballina Angelfish can live up to 10 years in captivity with proper care. Ensuring a stable environment, a varied diet, and regular tank maintenance are key factors in promoting a long and healthy life.

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

Routine care includes maintaining optimal water quality, providing a varied diet, and monitoring for signs of stress or illness. Regular water changes and avoiding overcrowding can prevent many common health issues. Supplementing their diet with vitamins can help prevent nutritional deficiencies and enhance their immune system.

Habitat

The Ballina Angelfish is native to the subtropical waters of the western Pacific Ocean, particularly around the eastern coast of Australia. It inhabits rocky reefs and coral-rich areas, where it can find ample food and shelter.

This species prefers environments with plenty of live rock and moderate water flow, replicating the conditions of its natural habitat. Providing a stable and enriching environment is crucial for its well-being in captivity.
