Common name: Tube Anemones

Cerianthidae, commonly known as Tube Anemones, are a family of ceriantharians that are distinct from true sea anemones. They are characterized by their long, tube-like structures made from secreted mucous and threads. Tube Anemones can add a unique aesthetic to a reef tank with their vibrant colors and flowing tentacles. They are nocturnal and often bury their tubes in the substrate, extending their tentacles at night to feed. They have a symbiotic relationship with certain species of clownfish, which may use them as a host, similar to the way they interact with true anemones.
