Common name: Mauritian Clownfish

General Information

The Mauritian Clownfish, also known as the Yellowbelly Clownfish, is a striking species in the aquarium trade. Known for its black body accented with white bands and a distinctive yellow belly, this clownfish is a favorite among hobbyists seeking a unique addition to their marine tanks. Unlike its more common relatives, the Mauritian Clownfish is endemic to the waters around Mauritius, making it a rare and prized specimen in the aquarium hobby.

Although not as popular as the Amphiprion ocellaris, the Mauritian Clownfish is gaining attention due to its unique coloration and relatively peaceful nature. It shares many characteristics with other clownfish but stands out due to its specific geographic origin and distinct appearance.

Care

Mauritian Clownfish require an aquarium that can mimic their natural reef environment. They thrive in tanks with live rock structures, which provide hiding spaces and territories. While they are adaptable to various marine foods, a diet that includes a mix of high-quality marine pellets, frozen mysis shrimp, and brine shrimp will support their health and vibrant coloration.

These clownfish are best suited for tanks of at least 100 liters (about 25 gallons) to accommodate their active nature and territorial behaviors. Stable water conditions and regular maintenance are crucial for their well-being.

Diet and Feeding

Mauritian Clownfish are omnivorous and benefit from a varied diet. In the wild, they consume a mix of algae, zooplankton, and small invertebrates. In captivity, they should be fed a balanced diet that includes marine-based pellets, flakes, and frozen foods like mysis and brine shrimp. Feeding them once or twice a day is sufficient, ensuring portions are small enough to be consumed within a few minutes to maintain water quality.

Behavior and Compatibility

The Mauritian Clownfish is generally peaceful, making it a good candidate for community tanks. However, like other clownfish, they can become territorial, especially when hosting an anemone. They may exhibit aggression towards other clownfish species or similarly shaped fish, particularly in smaller tanks.

They are compatible with a variety of reef-safe fish and invertebrates but should not be housed with overly aggressive species that may stress or harm them.

Reproduction

Like other clownfish, the Mauritian Clownfish is a protandrous hermaphrodite. In a group, the largest fish becomes the female, while the second largest becomes the breeding male. If the female is removed or dies, the dominant male will change sex to become the new female. Breeding pairs are monogamous, and the female lays eggs on a flat surface near their host anemone. The male guards and cares for the eggs until they hatch.

Symbiosis

The Mauritian Clownfish forms a symbiotic relationship with sea anemones, similar to other clownfish species. This mutualistic relationship provides the clownfish with protection from predators, while the anemone benefits from food scraps and increased water circulation due to the clownfish's movements.

In captivity, they can host with various anemone species, including Heteractis magnifica and Entacmaea quadricolor, providing a fascinating dynamic in reef aquariums.

Health and Common Issues

With proper care, Mauritian Clownfish can live up to 10 years in captivity. Maintaining optimal water conditions, a balanced diet, and a clean environment are essential for their health. They are susceptible to common marine diseases such as ich and brooklynella, so quarantine new tank additions and monitor water quality regularly.

When selecting a Mauritian Clownfish, choose individuals that are active and display vibrant colors, with no signs of disease or stress.

Habitat

Endemic to the waters around Mauritius, the Mauritian Clownfish inhabits coral reefs and lagoons. They prefer warm, shallow waters with plenty of live rock and anemones, thriving in stable conditions that mimic the gentle currents of their natural habitat.
