Care

Royal Dottybacks are hardy fish that adapt well to life in captivity. They thrive in well-established aquariums with plenty of rockwork and hiding spaces to establish territories. While they can be aggressive towards other dottybacks or similarly sized and shaped fish, they generally do well with larger, peaceful tank mates. A varied diet of meaty foods, such as mysis shrimp and brine shrimp, will help maintain their vibrant colors and overall health.

Reproduction

In the home aquarium, breeding Royal Dottybacks can be a challenge due to their aggressive nature. However, they are protogynous hermaphrodites, meaning they start life as females and can change to males if no male is present. Breeding pairs will lay eggs in a secure cave or crevice, and the male will guard and care for the eggs until they hatch.

Habitat

Pictichromis paccagnellae is native to the Indo-Pacific region, specifically found in reef environments. They prefer areas with abundant coral and rock formations where they can establish territories and find shelter from predators. In the wild, they are typically found at depths ranging from the surface down to about 40 meters.
