Care

Diadem Dottybacks are relatively easy to care for. They thrive in well-established aquariums with plenty of rockwork and hiding places. These fish can be territorial, so it's important to introduce them to the tank last to minimize aggression. They are carnivorous and should be fed a varied diet of meaty foods, including frozen mysis shrimp and brine shrimp.

Reproduction

In the home aquarium, Diadem Dottybacks can be bred with some effort. They are protogynous hermaphrodites, meaning they start life as females and can change to males if necessary. Breeding pairs will lay eggs in a secure cave or crevice, and the male will guard and tend to the eggs until they hatch.

Habitat

Diadem Dottybacks are found in the coral-rich environments of the Red Sea. They prefer reef habitats with plenty of crevices and overhangs for shelter. In the wild, they are often observed at depths ranging from shallow waters to about 40 meters deep.
