Common name: Saddleback Clownfish
General Information
The Saddleback Clownfish, scientifically known as Amphiprion polymnus, is a charming species known for its distinctive saddle-like white marking across its back. This unique pattern, along with its brown to black body and white face, sets it apart from other clownfish species. The Saddleback Clownfish has become a popular choice for aquarists due to its striking appearance and engaging behavior.
In the aquarium hobby, the Saddleback Clownfish is appreciated not only for its beauty but also for its role in symbiotic relationships with anemones. This species is moderately available in the trade, with both wild-caught and captive-bred individuals offered. Captive-bred specimens are often recommended due to their adaptability and reduced impact on wild populations.

Care
Saddleback Clownfish are best kept in aquariums that mimic their natural reef environment. They thrive in tanks with plenty of live rock and hiding places. A tank of at least 100 liters is recommended to provide ample space for swimming and territory establishment. Maintaining stable water conditions with appropriate filtration is crucial for their health.
To enrich their environment, consider adding anemones such as Heteractis crispa or Stichodactyla haddoni, with which they naturally associate. These anemones provide shelter and a sense of security for the clownfish.
Diet and Feeding
In the wild, Saddleback Clownfish are omnivorous, feeding on a mix of algae, plankton, and small invertebrates. In captivity, they should be offered a varied diet that includes high-quality marine flakes or pellets, along with frozen foods like brine shrimp and mysis shrimp. Feeding once or twice daily is sufficient, and care should be taken to avoid overfeeding.
Behavior and Compatibility
Saddleback Clownfish are known for their peaceful temperament, making them suitable for community reef tanks. They can, however, become territorial, especially when establishing a breeding pair or defending their anemone host. It's important to provide enough space to minimize aggression.
They are compatible with a variety of reef-safe fish and invertebrates but should not be housed with overly aggressive species that might intimidate them.
Reproduction
Like many clownfish, Saddleback Clownfish are protandrous hermaphrodites. They form monogamous pairs, with the dominant individual becoming female. Breeding occurs near their host anemone, where the female lays eggs on a flat surface. The male guards and aerates the eggs until they hatch. Raising the fry requires careful attention to diet and water quality.
Symbiosis
The Saddleback Clownfish has a symbiotic relationship with certain sea anemones, notably Heteractis crispa and Stichodactyla haddoni. This relationship provides the clownfish with protection from predators, while the anemone benefits from food scraps and cleaning by the clownfish.
Health and Common Issues
With proper care, Saddleback Clownfish can live for several years in captivity. It's important to maintain high water quality and a balanced diet to prevent common health issues like ich and marine velvet. Quarantine new additions to the tank to reduce the risk of disease.
When selecting a Saddleback Clownfish, look for vibrant colors and active behavior. Avoid individuals with torn fins or signs of disease.
Habitat
The natural habitat of the Saddleback Clownfish includes the shallow coastal waters and lagoons of the Indo-Pacific region, particularly around northern Australia, the Philippines, and Indonesia. They prefer environments with plenty of anemones and live rock, which offer both food and protection.
