Care

Sunburst Anthias are moderately difficult to care for, primarily due to their specific dietary needs. They thrive on a diet that includes a variety of small, meaty foods such as mysis shrimp, brine shrimp, and finely chopped seafood. Frequent feedings are necessary, as they have a high metabolism and are accustomed to constant grazing in the wild. A well-established aquarium with plenty of live rock for hiding and a strong water current is ideal for their well-being.

Reproduction

In the wild, Sunburst Anthias form harems consisting of one dominant male and several females. They are protogynous hermaphrodites, meaning females have the ability to turn into males if the dominant male perishes. In the aquarium, breeding Sunburst Anthias can be challenging, but it is possible with careful attention to water quality and providing a stress-free environment.

Habitat

Sunburst Anthias are found in the Indo-Pacific region, typically in coral-rich areas and steep outer reef slopes. They prefer depths ranging from 25 to 60 meters, where they can be seen swimming in large groups. Their natural habitat includes areas with strong currents, which helps hobbyists understand their needs for high water flow in the aquarium setting.
