Care
Due to its rarity and specific needs, the Ballina Angelfish is recommended for advanced aquarists. It requires a large, well-established aquarium with plenty of live rock for grazing and hiding. This species is known to be shy and may take some time to acclimate to a new environment. A varied diet of marine sponges, algae, and high-quality angelfish preparations is essential to maintain its health and coloration.
Reproduction
In the wild, Ballina Angelfish are believed to be pelagic spawners, releasing their eggs and sperm into the water column where fertilization occurs. However, breeding in captivity is extremely rare and not well-documented due to the scarcity of this species in the aquarium trade.
Habitat
The Ballina Angelfish is found in deep reef environments, typically between 50 to 150 meters. It prefers steep outer reef slopes and drop-offs, which makes it a challenging species to collect for the aquarium trade. Its natural habitat is characterized by clear waters with strong currents, which should be replicated in the home aquarium for the best care of this species.
