Common name: Western gregory

General information

The Midget Damselfish, scientifically known as Stegastes obreptus, is a small and resilient marine fish that is well-suited for the home aquarium. This species is recognized for its striking coloration, typically a dark body with a prominent white tail. It is a member of the Pomacentridae family, which includes other popular aquarium damselfishes.

Care

Midget Damselfish are hardy and can adapt to a range of aquarium conditions, making them suitable for both beginner and experienced aquarists. They are territorial and can become aggressive, especially in smaller tanks, so it's important to provide ample space and hiding places. A varied diet of meaty foods, algae, and high-quality commercial feeds will help maintain their health and coloration.

Reproduction

In the wild, Midget 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 be a challenging endeavor, requiring a well-established environment and careful monitoring.

Habitat

Stegastes obreptus is found in the Western Pacific, from the Great Barrier Reef to Samoa, and north to the Ryukyu Islands. They prefer shallow, coral-rich areas and are often observed living among branching corals like Acropora, which provide shelter and territory for these small fish.
