It requires at least a 70 gallon tank with lots of hiding places. The Midnight Angel starts out as a shy fish that requires lots of hiding places in a rocky Aqua-scaped aquarium with lots of caves/crevices and ample amounts of live rock for grazing on microalgae and diatoms. Place the rock work with multiple places to hide so they will feel secure enough to come out often. This will provide security, and the more secure it feels, the more it will come out into the open. The Black Nox Angelfish should be the only dwarf angelfish in the tank. 

Tankmates for Black Nox angelfish should be peaceful or semi-aggressive in nature and not be direct food competitors. It should also be noted that Black Nox angelfish can bite soft coral polyps, clam mantles, and zoanthids, but do not bother invertebrates such as shrimp, snails, and crabs if well fed.

Centropyge species like the Black Nox Angelfish are protogynous fishes. They start their life cycle as unsexed individuals and begin adult life as females. Differentiation in sex (female to male) will occur to the larger and more dominant individual within a group. Therefore, male Black Nox Angelfishes are usually bigger in size than the female counterpart, and has no distinguishable color differences between gender. 

Midnight Angelfishes are omnivores like the other species of angelfishes. It mostly feeds on algae. Tank feeding should include spirulina algae, marine algae, mysis shrimp with other fleshy organism such as brine or krill, and live rocks with algae for grazing. It should be fed 2 to 3 times a day to maintain a healthy immune system.
