Common name: Blackfinned Clownfish

General Information

The Blackfinned Clownfish, known scientifically as Amphiprion nigripes, is a captivating species native to the Maldives. This species is renowned for its striking appearance, characterized by a vibrant orange body and distinct black fins, which set it apart from other clownfish. A relatively rare find in the aquarium trade, the Blackfinned Clownfish is a prized addition for hobbyists seeking a unique and visually stunning fish.

In the wild, the Blackfinned Clownfish is typically associated with the anemone Heteractis magnifica, forming a mutualistic relationship that provides both species with benefits. This clownfish is less commonly found in the pet trade compared to other clownfish species, largely due to its limited geographic distribution.

Care

Caring for the Blackfinned Clownfish requires attention to detail, as they thrive best in aquariums that closely mimic their natural reef environment. An aquarium with a minimum volume of 100 liters is recommended to provide ample space for exploration and swimming. The inclusion of live rock and anemones can enhance their habitat, offering both shelter and enrichment.

Diet and Feeding

Blackfinned Clownfish are omnivorous, feeding on a diet that includes small invertebrates, algae, and zooplankton. In captivity, they should be offered a varied diet consisting of high-quality marine flakes, pellets, and frozen foods such as brine shrimp and mysis shrimp. Feeding should occur once or twice daily, with portions adjusted based on their consumption.

Behavior and Compatibility

Generally peaceful, the Blackfinned Clownfish can exhibit territorial behavior, especially around their host anemone. They are best kept in pairs or small groups in larger aquariums to minimize aggression. Compatibility with other reef-safe species is generally good, though they may display aggression towards conspecifics if space is limited.

Reproduction

Like other clownfish, Amphiprion nigripes are protandrous hermaphrodites, with the ability to change sex from male to female. This species forms monogamous pairs, and breeding in captivity can be achieved under optimal conditions. The female lays her eggs on a flat surface near the anemone, and the male tends to them until they hatch.

Symbiosis

The Blackfinned Clownfish maintains a symbiotic relationship with the anemone Heteractis magnifica. This relationship provides the clownfish with protection from predators, while the anemone benefits from food scraps and cleaning by the clownfish. In captivity, the presence of a host anemone can enhance the well-being of the Blackfinned Clownfish.

Health and Common Issues

With proper care, the Blackfinned Clownfish can live up to 10-15 years in captivity. Maintaining stable water conditions, a balanced diet, and regular tank maintenance are essential for their health. They are susceptible to common marine diseases, such as ich and brooklynella, so quarantine new additions and monitor for any signs of illness.

Habitat

Naturally found in the coral reefs of the Maldives, the Blackfinned Clownfish prefers shallow, warm waters with abundant anemones and live rock. These environments provide the necessary shelter and food resources that support their survival in the wild.
