Care

Caring for the Black Velvet Angelfish requires a well-established aquarium with plenty of live rock for grazing and hiding. This species can be sensitive to water quality, so maintaining pristine conditions is crucial. They are omnivores, with a diet that should include a variety of foods such as marine algae, spirulina, mysis shrimp, and other high-quality prepared foods to ensure a balanced nutrition.

Reproduction

In the wild, Black Velvet Angelfish are broadcast spawners, releasing eggs and sperm into the water column where fertilization occurs. In the home aquarium, breeding is rare, but with a large enough tank and optimal conditions, it is possible to observe spawning behavior.

Habitat

The Black Velvet Angelfish is found in the Western Pacific, particularly around the Northern Marianas, Guam, and possibly the southernmost islands of Japan. They inhabit coral reefs and rocky outcrops, typically at depths ranging from shallow waters to about 40 meters.

Due to their rarity and specific care requirements, the Black Velvet Angelfish is recommended for experienced aquarists who can provide the stable environment and specialized diet this species needs to thrive.
