The Midnight Angel is commonly referred to as the Black Nox Angelfish, Black Angelfish, Black Nox Angelfish, Nox Angelfish and Black Pygmy Angelfish. It has a solid black colored body that makes it stand out in the crowd of other fishes, and also contrast the brightly colored marine corals and fish species. The Midnight Angel is considered one of the most peaceful Angelfish and can co-exist with other peaceful Centropyge. It requires plenty of live rocks that help it to create multiple territories and should be kept in a tank not less than 30 gallon. The Midnight Angel makes an excellent addition to any community aquarium containing peaceful to semi- aggressive fish species. Although it might turn territorial towards their own kind and other Dwarf Angelfish, it can be housed in large aquarium supplying enough territory for each. The Midnight Angel is found nipping a variety of corals and sessile invertebrates including soft coral polyps, clam mantles, and zoanthids, but it does not bother any invertebrates like shrimps, snails and crabs; therefore is considered safe for reef tank but with caution. The diet should include marine algae, spirulina, high-quality angelfish preparations, and other meaty items such as brine or krill. Being an omnivore it is important to provide a balanced diet of algae and meaty foods in order to provide all the necessary vitamins and nutrition required. The Midnight Angel should be fed two to three times daily for its continued good health and to maintain a healthy immune system. It is necessary to provide them plenty of live rocks that encourage the growth of algae on which it can graze in between feedings. The Midnight Angel thrives well in a temperature range of 72-78 degrees Fahrenheit and pH of 8.1-8.4.
The Angelfish family is a group of colorful and elegant fish that are adored by both the serious and casual observer. These fish are mainly available to the hobbyist under the Genus Pomacanthus and Centropyge. Pomacanthus Angels are the larger more robust species. The Centropyge Genus are made up of smaller fish that feed primarily on algae from the reef surface. The adult Pomacanthus Angels usually have long dorsal and anal fins and a rounded face. The Pomacanthus Angels will change color quite dramatically from their juvenile stage to adult stage. The Centropyge Angels are found predominantly in the Indo-Pacific while only a couple of species, like the Pygmy and Flameback Angels, are found in the Atlantic and Caribbean. At the same time, the Pomacanthus Angels dominate the Atlantic and Caribbean while in the Indo-Pacific they are less prominent. The Centropyge Angels do not change color dramatically from their juvenile stage to adult stage. These smaller Angels are often seen milling around reefs which they use for both shelter and as a food source. Angelfish are differentiated from Butterflyfish by the small spine that extends from the bottom of their rear gill cover.This species feeds heavily on diatoms growing on the aquarium glass or decoration, and live rock or a growth of filamentous algae will facilitate acclimation.This fish is coal black, truly surprising.
