General information

The Yellowtail Damselfish, Neopomacentrus xanthurus, is a small and vibrant fish that is popular among reef aquarium enthusiasts. It is known for its striking blue body and contrasting yellow tail, which adds a splash of color to any marine aquarium. This species is relatively hardy and can be a good choice for both beginner and advanced aquarists.

Care

Yellowtail Damselfish are hardy and adaptable, making them suitable for a variety of aquarium setups. They thrive in well-established tanks with plenty of rockwork and hiding spaces. While they are generally peaceful, they can become territorial, especially in smaller tanks. A varied diet of meaty foods, algae, and high-quality commercial feeds will help maintain their health and coloration.

Reproduction

In the wild, Yellowtail Damselfish are known to form breeding pairs or small groups. They lay their eggs on a flat surface, and the male guards and tends to the eggs until they hatch. In the aquarium, breeding can occur if the environment is stable and the fish are well-fed, but raising the fry can be challenging.

Habitat

Neopomacentrus xanthurus is native to the Indo-Pacific region, where it is commonly found in shallow reefs and lagoons. They prefer areas with abundant coral growth and are often seen darting among the branches of stony corals or hiding in crevices.
