Common name: Black-vent damsel

General information

The Blacktail Dascyllus, Dischistodus melanotus, is a small and attractive damselfish species known for its striking coloration and active behavior. This fish is characterized by its white body with three black vertical stripes and a distinct black tail, which gives it its common name. It is a hardy species that adapts well to life in captivity, making it a popular choice for both beginner and experienced aquarists.

Care

Blacktail Dascyllus are relatively easy to care for. They thrive in well-established aquariums with plenty of live rock for hiding and grazing. While they are generally peaceful, they can become territorial, especially in smaller tanks. It's important to provide ample space and hiding places to minimize aggression. A varied diet of meaty foods and high-quality marine flakes or pellets will help maintain their health and coloration.

Reproduction

In the wild, Blacktail Dascyllus form breeding pairs or small groups. They are known to spawn regularly in an aquarium setting if the environment is stable and they are well-fed. The male will prepare a flat surface, usually on a rock or coral, where the female will lay her eggs. The male then guards and tends to the eggs until they hatch.

Habitat

Native to the Indo-Pacific region, Blacktail Dascyllus are commonly found in shallow reefs and lagoons, often associating with branching corals like Acropora. They prefer environments with strong water movement and plenty of hiding spots. In the wild, they are typically found at depths ranging from 1 to 12 meters (3 to 40 feet).

Geographical distribution includes areas from East Africa to the central Pacific, including the Red Sea, Indian Ocean, and Western Pacific Ocean.
