Common name: Scaly damsel

General information

The Halfmoon Damsel, scientifically known as Pomacentrus lepidogenys, is a small and vibrant fish that adds a splash of color to any marine aquarium. They are part of the Pomacentridae family, which is known for the many colorful species it includes, commonly referred to as damselfish. This species is recognized by its deep blue body and distinct yellow tail, which gives it the alternative names Yellowtail Blue Damsel and Yellowtail Demoiselle.

Care

Halfmoon Damsels are hardy and adaptable, making them suitable for both beginner and experienced aquarists. They thrive in well-established aquariums with plenty of rockwork and hiding spaces. While they are generally peaceful, they can become territorial, especially towards conspecifics or similar-sized fish. It's important to monitor their behavior to prevent aggression in a community tank setting. A varied diet of meaty foods, algae, and high-quality marine flake or pellet food will help maintain their health and coloration.

Reproduction

In the wild, Halfmoon Damsels are known to form breeding pairs or small harems. They exhibit parental care, with males typically guarding and tending to the eggs until they hatch. Breeding them in captivity can be challenging but rewarding for dedicated hobbyists willing to provide the right conditions and care for the larvae.

Habitat

Halfmoon Damsels are found in the Indo-Pacific region, from the eastern Indian Ocean to the western Pacific. They prefer shallow, coral-rich environments and are often seen darting among the branches of stony corals or hiding in crevices.
