Common name: Red Sea Feather Star

General information

The Red Sea Feather Star, scientifically known as Manucomplanus varians, is a captivating and colorful crinoid that is often sought after by advanced marine aquarium enthusiasts. Feather stars are echinoderms, related to sea stars and sea urchins, and are known for their ornate feather-like arms which they use for both locomotion and feeding. Manucomplanus varians is particularly noted for its vibrant coloration, which can range from deep reds to purples, and its intricate arm structure.

Care

Caring for Manucomplanus varians requires a well-established aquarium with stable water conditions and moderate to strong water flow to mimic their natural habitat. They are suspension feeders, capturing plankton and other fine food particles from the water column with their feathered arms. A varied diet of phytoplankton, zooplankton, and other fine particulate foods is essential for their health. Due to their specific feeding requirements, they are recommended for experienced hobbyists.

Reproduction

In the wild, feather stars reproduce by releasing sperm and eggs into the water column, where fertilization occurs externally. In the aquarium, successful breeding is rare, but hobbyists may observe spawning behavior if conditions are optimal.

Symbiosis

While Manucomplanus varians does not have notable symbiotic relationships like some other marine organisms, its presence can enhance the biodiversity of a reef tank by providing a unique and dynamic element to the ecosystem.

Habitat

Manucomplanus varians is native to the Red Sea and surrounding waters. They are typically found in reef environments, attaching themselves to substrates with their prehensile cirri. In the aquarium, they require structures to cling to, such as live rock or coral skeletons.
