Common name: Mussel Worm

General information

The Feather Duster Worm, scientifically known as Nereis vexillosa, is a captivating marine polychaete worm that is popular among reef aquarium enthusiasts. This species is part of the family Nereididae and is known for its beautiful, fan-like crown of radioles, which it uses for feeding and respiration. The worm's body is hidden within a tough, protective tube that it secretes.

Care

Feather Duster Worms are relatively easy to care for in a well-established reef aquarium. They require stable water conditions and a moderate to strong water flow to help them capture food particles. It's important to maintain good water quality and avoid copper-based medications, as these can be harmful to polychaete worms.

Reproduction

Reproduction in Nereis vexillosa typically involves the release of gametes into the water column, where fertilization occurs externally. In the aquarium, this process is rarely observed, and the successful rearing of offspring is quite challenging.

Symbiosis

While not known for any specific symbiotic relationships, Feather Duster Worms contribute to the overall health of the reef ecosystem by filtering water and reducing particulate matter.

Habitat

Nereis vexillosa is found in a variety of marine environments, from intertidal zones to deeper waters. They are often associated with sandy or muddy substrates where they can anchor their tubes and extend their crowns to feed.
