Common name: Orange-fin Anemonefish

General Information

The Orange-fin Anemonefish, Amphiprion chrysopterus, is a striking species known for its vibrant orange fins and contrasting dark body. This species is a favorite among aquarists who appreciate its bold coloration and dynamic presence in a marine aquarium. Unlike its more famous cousin, the Amphiprion ocellaris, the Orange-fin Anemonefish is less commonly seen in the pet trade but is highly prized for its unique appearance.

Native to the Western Pacific, particularly around the Solomon Islands and Vanuatu, this species often inhabits coral reefs and lagoons, where it forms symbiotic relationships with anemones. Its striking appearance and engaging behavior make it an attractive choice for experienced hobbyists.

Care

While the Orange-fin Anemonefish is relatively hardy, it requires a well-established aquarium with stable water conditions. A tank of at least 100 liters is recommended to provide ample space for swimming and to accommodate an anemone host. The aquarium should mimic the natural reef environment with live rock and hiding spots.

This species thrives in a tank with moderate water flow and a temperature range of 24-28°C. Proper filtration and regular water changes are essential to maintain water quality. As with other anemonefish, providing a host anemone such as Heteractis magnifica can enhance their natural behaviors.

Diet and Feeding

Amphiprion chrysopterus is an omnivore, feeding on a varied diet in the wild that includes zooplankton and small invertebrates. In captivity, they should be offered a balanced diet of high-quality marine pellets, flakes, and frozen foods such as mysis shrimp and brine shrimp.

Feed them once or twice a day, ensuring that they consume all the food within a few minutes to prevent overfeeding and maintain water quality. Supplements such as vitamins can be added to their diet to boost their immune system and enhance coloration.

Behavior and Compatibility

Orange-fin Anemonefish are semi-aggressive, particularly when defending their territory or anemone host. They are best kept in pairs or small groups, but care should be taken when introducing them to a community tank. They may show aggression towards other anemonefish or similarly shaped species.

They are generally compatible with other peaceful reef-safe fish and invertebrates. However, avoid housing them with overly aggressive species that might intimidate or outcompete them for resources.

Reproduction

Like other clownfish, Amphiprion chrysopterus are protandrous hermaphrodites. In a pair, the larger fish becomes the female, and the smaller one the male. Breeding pairs will lay eggs on a flat surface near their host anemone, with the male guarding the eggs until they hatch.

Symbiosis

This species forms a mutualistic relationship with several types of sea anemones, including Heteractis magnifica and Stichodactyla gigantea. The anemone provides protection with its stinging tentacles, while the clownfish offers food scraps and defense against predators.

Health and Common Issues

With proper care, Amphiprion chrysopterus can live up to 10 years in captivity. Maintaining high water quality and a varied diet is crucial for their health. They are susceptible to common marine diseases such as ich and brooklynella, so quarantine new tank additions and monitor for signs of illness.

Habitat

Amphiprion chrysopterus is found in coral reefs and lagoons in the Western Pacific. They prefer warm, shallow waters with plenty of live rock and anemones, thriving in environments that replicate the gentle currents and stable conditions of their natural habitat.
