Common name: Christmas Tree Worms

Serpulidae, commonly known as Christmas Tree Worms, Tube Worms, or Feather Duster Worms, are a family of sedentary polychaete worms. They are known for their beautiful, spiraling, and colorful crowns which are used for feeding and respiration. These worms anchor themselves in hard substrates, such as live rock or coral skeletons, by secreting a calcareous tube around their bodies. In the aquarium, they are appreciated for their unique appearance and the role they play in the ecosystem, helping to filter the water. They are generally reef safe and can add a splash of color and natural behavior to the tank.
