Care

White-tailed Damselfish are relatively easy to care for. They thrive in well-established aquariums with plenty of live rock for hiding and grazing. They are omnivorous and will accept a variety of foods, including frozen and flake foods, but a diet that includes marine-based proteins and algae will help maintain their coloration and health.

Reproduction

Like many damselfish, Pomacentrus albicaudatus are known to be territorial during breeding. They lay their eggs on flat surfaces, where the male will guard and tend to them until they hatch. The fry can be raised in a separate tank with appropriate food, such as rotifers initially, followed by baby brine shrimp.

Habitat

The White-tailed Damselfish is native to the Western Pacific, where it is commonly found in coral-rich areas and lagoons. They prefer environments with plenty of live coral cover and are often observed at depths ranging from shallow waters to about 12 meters deep.
