Common name: Dusky angelfish
General information
The Midnight Angelfish, scientifically known as Centropyge nox, is a small and elusive species of marine angelfish. It is known for its striking all-black coloration, which can add a dramatic contrast to the vibrant hues of a reef aquarium. This species is less commonly seen in the trade compared to other angelfish due to its nocturnal habits and preference for deeper waters.

Care
Midnight Angelfish require a well-established aquarium with plenty of live rock for grazing and hiding. They are generally peaceful but can be territorial towards other angelfish. A varied diet of marine algae, spirulina, mysis shrimp, and other high-quality prepared foods is essential for their health. Caution should be exercised when housing them with small invertebrates or corals, as they may nip at soft and stony corals or clam mantles.
Reproduction
Like many marine angelfish, Midnight Angelfish are protogynous hermaphrodites, meaning they are born female and have the potential to turn male if the dominant male is absent. Breeding in captivity is rare, and little is known about their reproductive habits in the wild.
Habitat
Midnight Angelfish are found in the Indo-Pacific region, typically in reef slopes and lagoons at depths ranging from 10 to 30 meters. They prefer areas with abundant coral growth and crevices to hide during the day, emerging at dusk to feed.
