Common name: Three-spot cardinalfish

General information

The Three-spot Dascyllus, also known as the Domino Damselfish, is a small and robust marine fish that is popular among aquarists for its striking coloration and hardy nature. This species is characterized by its deep black body with three prominent white spots, one on the forehead and two laterally on the sides. As juveniles, they exhibit more pronounced white spots, which can fade as they mature.

Care

Domino Damselfish are known for their resilience and can be a good choice for beginner aquarists. They thrive in well-established aquariums with plenty of rockwork and hiding spaces. While they are not picky eaters, a varied diet of meaty foods, algae, and high-quality commercial feeds will help maintain their health and coloration. It's important to note that they can become territorial, especially in smaller tanks, so providing adequate space and hiding places is crucial.

Reproduction

In the wild, Three-spot Dascyllus breed in groups, with a dominant male displaying to attract females to his territory, where he will guard the eggs until they hatch. In the home aquarium, breeding is less common but can occur if the environment is stable and the fish are well-fed.

Symbiosis

While not as iconic in their symbiotic relationships as clownfish, Three-spot Dascyllus juveniles are sometimes found seeking refuge among the tentacles of larger anemones, similar to clownfish. However, this behavior is less common in adults and in the aquarium setting.

Habitat

The Three-spot Dascyllus is native to the Indo-Pacific region, where it is commonly found in coral-rich areas and lagoons. They prefer the upper parts of reefs where they can be seen swimming in small groups or individually.
