Common name: Red Saddleback Anemonefish

Scientific name: Amphiprion ephippium (Bloch, 1790)

General Information

The Red Saddleback Anemonefish, scientifically known as Amphiprion ephippium, is a striking species popular among aquarists for its vibrant colors and unique patterns. It is easily recognizable by its bright orange to red body and the distinctive black saddle-like marking on its back, which gives this species its common name. Unlike many other clownfish, the Red Saddleback lacks the typical white bands, making it stand out in any aquarium setting.

This species is native to the Indo-Pacific region, particularly around the Andaman Sea, Nicobar Islands, and parts of Southeast Asia. Its natural habitat includes sheltered lagoons and coral reefs, where it often forms symbiotic relationships with certain types of anemones.

Care

The Red Saddleback Anemonefish is moderately easy to care for, making it suitable for aquarists with some experience. It thrives in a well-established marine aquarium with stable water conditions. A tank size of at least 100 liters is recommended to provide ample space for swimming and to accommodate their territorial nature.

To mimic their natural environment, include live rock and anemones in the tank. This helps reduce stress and encourages natural behaviors. Adequate filtration and regular water changes are crucial for maintaining water quality.

Diet and Feeding

In the wild, Red Saddleback Anemonefish are omnivores, feeding on a variety of small invertebrates and algae. In captivity, they should be offered a varied diet that includes high-quality marine pellets, frozen foods like mysis shrimp, and finely chopped seafood. Feeding once or twice a day is sufficient, ensuring that the portions are small enough to be consumed quickly.

Behavior and Compatibility

Red Saddleback Anemonefish are known for their semi-aggressive temperament, especially towards other clownfish species. They can be territorial, particularly when hosting an anemone. It's advisable to keep them in pairs or small groups, ideally introduced to the tank simultaneously to minimize aggression.

They are compatible with other peaceful marine species, but caution should be taken when introducing other clownfish species or similarly sized fish to avoid territorial disputes.

Reproduction

Like many clownfish, the Red Saddleback is a protandrous hermaphrodite, meaning individuals start life as males and can become females as they grow. Breeding pairs form a monogamous bond, with the female laying eggs on a flat surface near their host anemone. The male takes on the role of guarding and aerating the eggs until they hatch.

Symbiosis

The Red Saddleback Anemonefish often forms symbiotic relationships with anemones such as Entacmaea quadricolor and Heteractis crispa. This mutualistic relationship provides protection for the clownfish from predators, while the anemone benefits from food scraps and enhanced water circulation provided by the clownfish's movements.

Health and Common Issues

With proper care, Red Saddleback Anemonefish can live up to 10 years in captivity. It's important to maintain stable water parameters and provide a nutritious diet to prevent common health issues like ich and brooklynella. Regular monitoring and prompt treatment of any signs of illness are essential.

Habitat

In their natural habitat, Red Saddleback Anemonefish are found in warm, shallow waters of coral reefs and lagoons. They prefer areas with plenty of live rock and anemones, which provide shelter and breeding grounds. Replicating these conditions in captivity helps ensure their health and well-being.
