Common name: Mamo

General information

The Dusky Damselfish, Stegastes nigricans, is a small, robust fish known for its territorial behavior and adaptability to various environments. It is a member of the Pomacentridae family, which includes other damselfish and clownfish. This species is often recognized by its dark body and the distinctive black spot at the base of its pectoral fin. In the wild, they play a role in the ecosystem by defending their algae gardens from other fish, which helps to maintain algal diversity.

Care

Dusky Damselfish are hardy and can be a good choice for beginner aquarists. They require an aquarium with plenty of rockwork and hiding spaces to mimic their natural habitat. Aggressive by nature, especially when defending their territory, they should be kept with other fish that can hold their own. A varied diet of meaty foods, herbivore flakes, and pellets will keep them healthy.

Reproduction

In the wild, Dusky Damselfish are known to be substrate spawners, laying their eggs on flat surfaces where the male will guard and tend to them until they hatch. In the aquarium, breeding can occur if a stable pair is established, and the tank environment is well-maintained.

Habitat

Dusky Damselfish are found in a variety of reef environments, from shallow lagoons to deeper outer reefs. They are common in the Indo-Pacific region, from East Africa to the Hawaiian, Marquesan, and Ducie islands, north to southern Japan, and south to Lord Howe Island.
