Common name: feather duster

General information

The Feather Duster Worm, scientifically known as Sabellastarte magnifica, is a captivating marine invertebrate that is popular among reef aquarium enthusiasts. This species belongs to the family Sabellidae and is known for its beautiful crown of radioles, which resemble a feather duster—hence the name. These radioles are not only visually striking but also serve an important function in filter feeding, as the worm uses them to catch plankton and other small particles from the water column.

Care

Feather Duster Worms are relatively easy to care for in a well-established reef aquarium. They require a stable environment with good water quality, moderate to low water flow, and a supply of fine particulate food. It's important to ensure that the aquarium is free of predators that may harm these worms, such as certain species of wrasses and large angelfish.

Reproduction

In the wild, Sabellastarte magnifica reproduces by releasing gametes into the water column, where fertilization occurs externally. In the aquarium, however, reproduction is less common but can occur if conditions are ideal. Hobbyists may observe the release of a cloud of gametes if a population of these worms is well-established.

Habitat

Feather Duster Worms are found in tropical marine environments, often in coral reefs or among rocks where they can anchor their tubes. They are widespread in the Indo-Pacific region, from the Red Sea to the Hawaiian Islands, and from Japan to Australia.
