Half Black Angelfish description
Just as with most Angelfish species, they have no distinguishing color variation between the male and female sex, which makes it difficult to breed them in captivity.
Half Black Angelfish in the ideal aquarium
Setting up the best tank for the Half Black Angelfish will require a well filtered minimum of 70 gallons /265 litres tank set up within the minimum requirements of a saltwater tank which includes a zero ammonia level and nitrates/nitrites level less than 2 ppm.
The water condition should be subject to frequent water changes, replacing more than 20% of the water every 2 weeks. The tank should provide as well plenty of live rock to provide them with enough hiding places and facilitate algae growth upon which they graze.
These species can be aggressive to other Angelfish relatives which makes it suitable to be the only Angelfish species in the tank. However, they can do well with other similar sized and semi-aggressive fish species.
They are not reef safe, as they would often nip at and even eat your precious soft and stony polyp corals, sessile invertebrates, clam mantles and zoanthids.
Half Black Angelfish feeding
They are omnivores and would feed on a variety of meaty food, vegetable matters and other high quality prepared foods including spirulina, mysis and brine shrimp, and marine algae matters. They should be fed thrice a day with as much as they can finish in a few minutes.
