Common name: Neon damsel

General information

The Neon Damselfish, scientifically known as Pomacentrus coelestis, is a vibrant and active fish that adds a splash of color to any saltwater aquarium. This species is known for its brilliant blue hue, which can range from a deep cobalt to a bright sky blue, depending on the light and angle. They are relatively small, reaching up to 6 centimeters in length, and are a popular choice among reef hobbyists due to their hardiness and ease of care.

Care

Neon Damselfish are hardy and adaptable, making them suitable for both beginner and advanced 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 advisable to introduce them to the aquarium at the same time to minimize aggression. A varied diet of meaty foods, algae, and high-quality marine flake or pellet food will keep them healthy and maintain their vibrant coloration.

Reproduction

In the wild, Neon Damselfish are known to form breeding pairs or small groups. They are egg-layers, with the male preparing a nesting site where the female will deposit her eggs. The male then guards and tends to the eggs until they hatch. In the aquarium, breeding can occur, but raising the larvae can be challenging due to their small size and specific feeding requirements.

Habitat

Pomacentrus coelestis is native to the Western Pacific Ocean, where it is commonly found in coral-rich areas of lagoons and outer reefs. They prefer shallow waters and are often observed at depths ranging from just below the surface to about 12 meters. Their natural habitat includes regions such as the Great Barrier Reef, New Caledonia, and the Solomon Islands.
