Black Nox Angelfish in the ideal aquarium
Setting up the best aquarium for the Black Nox Angelfish will require a well filtered tank within the minimum requirement of a saltwater aquarium and having a minimum of 70 gallons / 378.5 litres with lots of rockwork and caves to provide them with hiding places.
They are peaceful as juveniles, but as they get older they turn aggressive for no just cause.
As semi-aggressive, they are unsuitable tank mates with most species. As a matter of fact, they can be extremely aggressive to similar Dwarf Angelfish species, so they should be the only Dwarf Angelfish in your tank.
These species are not compatible with reef tanks, as they will often nip and feed on your precious Corals polyps, Clam mantles and Zoanthids.
Black Nox Angelfish feeding
They are omnivores and will feed on a varying diet of meaty and vegetable foods. The tank should also have lots of live rock that encourages the growth of algae matters upon which they will graze.
Black Nox Angelfish breeding
These species lack visible color differences between the male and female which makes it difficult to select mates and breed in captivity.
With proper care, the Black Nox Angelfish can live up to 15 years and grow up to 4’’ (10.16cm).
