Common name: red polyp octocoral

General information

The Northern Sea Fan, Swiftia exserta, is a gorgonian coral known for its delicate, fan-like appearance. It is a non-photosynthetic species, meaning it does not rely on light for its nutrition but instead captures plankton and other small particles from the water column. This attribute makes it an interesting species for advanced aquarists who are looking to diversify their reef tanks with unique and challenging species.

Care

Caring for Swiftia exserta requires a well-established aquarium with stable water conditions. Strong water flow is essential to mimic its natural habitat and facilitate feeding. Since it is a non-photosynthetic coral, it requires regular feeding with planktonic foods or other fine particulate foods designed for filter feeders. It is important to maintain excellent water quality, as this species is sensitive to elevated nutrient levels.

Symbiosis

While Swiftia exserta does not have the same type of symbiotic relationships as clownfish and anemones, it does provide habitat for a variety of small marine organisms. In the wild, tiny crustaceans and other invertebrates may take refuge among its branches, and similar interactions can occur in the home aquarium.

Habitat

Swiftia exserta is typically found in deeper, cooler waters ranging from the North Atlantic to the Mediterranean Sea. It often grows on vertical surfaces or overhangs where strong currents can deliver a steady supply of food particles.
