Common name: Midnight Angelfish

General Information

The Midnight Angelfish, scientifically known as Centropyge nox, is a captivating and enigmatic species cherished by marine aquarists. With its striking, deep black coloration, this angelfish is a stunning addition to any saltwater aquarium. Despite its mysterious appearance, the Midnight Angelfish is relatively hardy and adaptable, making it a popular choice for intermediate aquarists.

This species is native to the Indo-Pacific region, particularly around the reefs of the Philippines, Indonesia, and the Great Barrier Reef. It is well-suited for reef aquariums due to its manageable size and generally peaceful temperament, though some caution is advised.

Care

Midnight Angelfish thrive in well-established marine aquariums with plenty of live rock for grazing and hiding. They require stable water conditions and a tank size of at least 200 liters (approximately 50 gallons) to ensure ample swimming space and territory.

To mimic their natural habitat, the aquarium should include various hiding spots and rock structures. These features not only provide security but also encourage natural behaviors like grazing and exploring.

Diet and Feeding

In the wild, Midnight Angelfish are omnivores, feeding on algae, small invertebrates, and detritus. In captivity, they should be offered a varied diet that includes high-quality marine algae, spirulina-based foods, and occasional meaty treats like mysis shrimp and brine shrimp.

Feeding should occur two to three times daily, with portions that can be consumed within a few minutes. A diverse diet supports their health and enhances their striking coloration.

Behavior and Compatibility

The Midnight Angelfish is generally peaceful but may exhibit territorial behavior, especially towards other dwarf angelfish. They are best kept singly or as a mated pair in larger aquariums to minimize aggression.

While they are considered reef-safe with caution, they may occasionally nip at soft corals and clam mantles. Careful observation and a well-balanced diet can mitigate this behavior.

Reproduction

Breeding Midnight Angelfish in captivity is challenging and rarely successful. They are broadcast spawners, releasing eggs and sperm into the water column. Successful breeding requires precise conditions and a separate, dedicated breeding setup.

Health and Common Issues

With proper care, Midnight Angelfish can live for up to 5-7 years in captivity. Ensuring a stable environment and a balanced diet are crucial for their longevity.

When selecting a Midnight Angelfish, look for active individuals with smooth, unblemished fins and vibrant, uniform coloration. Avoid fish showing signs of stress or disease, such as faded colors or erratic swimming.

Routine tank maintenance, including regular water changes and monitoring of water parameters, is essential to prevent common marine diseases such as ich and bacterial infections.

Habitat

The Midnight Angelfish is found in coral reefs and rocky outcrops in the Indo-Pacific region. They prefer habitats with abundant hiding places and ample algae growth for grazing.

In captivity, replicating these conditions with a well-aquascaped tank will support their natural behaviors and overall well-being.
