Care
Yellowtail Blue 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 in smaller tanks. 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 home aquarium, Chromis enchrysura may spawn if they are kept in a group with a stable environment. They are egg-layers, with the male typically preparing a flat surface where the female will lay her eggs. The male then guards and tends to the eggs until they hatch.
Habitat
Yellowtail Blue Damselfish are found in the Western Pacific, from the Great Barrier Reef to Samoa, and north to the Ryukyu Islands. They prefer reef environments and are typically found at depths ranging from shallow waters to about 12 meters deep.
