Info

(Bleeker, 1853)

Centropyge nox, also known as the Midnight Angelfish, Dwarf Midnight Angelfish and Black Nox Angelfish is uniformly black over its entire body.

It is important to provide Centropyge nox plenty of live rock and a well aquascaped aquarium with caves, archways and overhangs to swim through or hide in.

Centropyge nox has no distinguishable differences in color between male to female.

Sex and mating

The $lat are female from birth. If two fish are put together, then the more dominant animal becomes the male (=protogyne hermaphrodite).
It is best to put two fish of different sizes at the same time. If a fish is already present, then the new fish should be either much smaller or larger. If a larger fish is added, which would be an advantage, then the internal aggression is not as pronounced. The difference in size can be an advantage when pairing up, but there will still be scuffles until the sexing is complete.

In nature,dwarf emperors live in pairs or in harem groups, i.e., one male with several females, usually among coral reefs.

Reefsafe
Anyone who purchases a $lat must expect that this LPS will nibble on or damage SPS corals, giant clams, and gorgonians. Of course, there may be differences depending on the individual animal, which is repeatedly reported in many forums. In terms of its general diet, $lat feeds mainly on algae, small invertebrates, and sponges. Nibbling is in the fish's genes, so it is just as common in captive-bred fish as it is in wild-caught fish. Perhaps not quite as strongly.

Keeping the fish in pairs can sometimes help, but it can also cause even more damage by imitating the partner.

If the coral is growing very well or has reached a certain size, the damage caused by nibbling should be tolerable.

The diet of the Midnight Angelfish in the wild is a varied diet consisting of algae and crustaceans. In the reef aquarium it should include marine algae, mysid shrimp and other meaty fare, and as before already described plenty of live rock for grazing.

Husbandry know-how of owners

Centropyge nox is one addition that is more likely to behave itself in the reef aquarium. In my eyes one of the less aggressive of the genus, Centropyge nox is initially shy, can be kept with other Centropyge Angelfish species providing they are introduced simutaneously and that the other fish is not one of the more aggressive of the genus. It is not a good reef dweller and may nip at soft coral polyps, clam mantles, and zoanthids. Centropyge nox are generally peaceful fish but will often quarrel with members of their own species and even genus if they look similar enough. There are reports generalizing this species are 'reef safe', we strongly advise to add them to a reef with extreme caution. Many of genus Centropyge will behave like model citizens for a while, but one day will go after corals and clams for no reason. There are occasional specimens that live very long lives in reef aquaria as peaceful citizens but the majority of these fish will often turn for no apparent reason when they are older.

Mein Schwarzer ist nun 3 Jahre alt. Hatte keine Probleme mit dem eingewöhnen ging an alles was fressbar ist nur ist er sehr scheu und meist versteckt, man sieht ihn meist nur vorbeihuschen es sei den er ist hungrig dan kann er auch an der Scheibe betteln. Hatte Anfangs mit dem Weißkehl Doctor probleme der ihn gegenüber agressiv war was sich aber nach 2 Tagen legte. Hat sich bis jetzt an keine Korallen vergriffen.
