Care

Royal Dottybacks are moderately easy to care for but can be territorial, especially towards conspecifics or similar-looking fish. They thrive in well-established aquariums with plenty of rockwork and hiding spaces. A varied diet of meaty foods, such as mysis shrimp and brine shrimp, supplemented with high-quality marine pellets, will help maintain their vivid coloration and health.

Reproduction

In the wild, Pseudanthias regalis forms harems consisting of a single dominant male and several females. If the male is lost, the largest female will often change sex to become the new male, a phenomenon known as protogyny. Breeding in captivity is challenging and not commonly achieved by hobbyists.

Habitat

Native to the Indo-Pacific region, Royal Dottybacks are typically found in coral-rich areas and steep reef slopes. They prefer depths ranging from 10 to 60 meters, where they can be seen darting in and out of the reef structure.
