Common name: tubeworm
General information
Serpula vermicularis, commonly known as the European calcareous tubeworm or feather duster worm, is a species of segmented marine worm belonging to the family Serpulidae. These worms are known for their beautiful, fan-like crowns which they use for feeding and respiration. The crown, or radioles, can come in a variety of colors including red, orange, yellow, or white, making them an attractive addition to the marine aquarium.
The calcareous tube that Serpula vermicularis constructs is a unique feature, providing the worm with protection from predators and environmental stress. These tubes can become encrusted with coralline algae, blending into the reef environment.

Care
Keeping Serpula vermicularis in a reef aquarium requires stable water conditions and good water quality to mimic their natural habitat. They prefer areas with moderate to strong water flow which helps them capture food particles suspended in the water. It's important to ensure that there are no aggressive tank mates that might damage their delicate crowns.
Feeding these worms consists of providing a steady supply of fine particulate organic matter, such as phytoplankton or specially formulated commercial foods for filter feeders.
Reproduction
In the wild, Serpula vermicularis reproduces by releasing eggs and sperm into the water column, where fertilization occurs externally. In the aquarium, successful breeding is rare, but with optimal conditions, it is possible to observe spawning behavior.
Symbiosis
While not known for any specific symbiotic relationships, Serpula vermicularis contributes to the biodiversity and balance of the reef aquarium by participating in nutrient cycling and providing a unique aesthetic.
Habitat
Serpula vermicularis is found in a range of marine environments from shallow waters to depths of over 200 meters. They are widespread in the Northeast Atlantic, from the Arctic down to the Mediterranean and West Africa. They often attach to hard substrates such as rocks, shells, or man-made structures.
