Common name: Giant Tube Anemone

General information

The Giant Tube Anemone, Pachycerianthus maua, is a striking marine invertebrate known for its long, tube-like structure and beautiful, feathery tentacles. Unlike true anemones, it belongs to the order Ceriantharia, which are tube-dwelling anemones that secrete a fibrous tube into the sediment. They are nocturnal creatures, often extending their tentacles at night to capture prey.

Care

Caring for Pachycerianthus maua requires a deep sand bed for it to anchor its tube and enough space for the full extension of its tentacles. They prefer low to moderate water flow and lighting. Feeding should consist of meaty foods like chopped fish, shrimp, or other suitable marine-based foods.

Reproduction

Reproduction in tube anemones is not well documented in home aquariums. In the wild, they can reproduce both sexually, by releasing gametes into the water column, and asexually, by budding.

Symbiosis

While not hosting fish like clownfish-anemone symbiosis, tube anemones can have commensal relationships with certain species of fish and invertebrates that may seek refuge among their tentacles.

Habitat

Pachycerianthus maua is typically found in sandy or muddy substrates in reef environments. They can be found at various depths, often ranging from shallow waters to depths beyond typical recreational diving limits.
