Common name: Tangled Tubeworm

General information

Filograna implexa, commonly known as the Tube Worm, is a species of serpulid polychaete worm. These worms are known for their intricate calcareous tubes, which they construct using secreted calcium carbonate. The tubes serve as both a protective structure and a means of anchoring the worm to the substrate. Tube Worms are filter feeders, using their feathery tentacles to capture plankton and other small particles from the water column.

Care

In the aquarium, Filograna implexa requires a stable environment with good water quality. They thrive in tanks with moderate to strong water flow, which facilitates their filter-feeding behavior. It's important to maintain calcium levels to support tube growth. They do not require additional feeding if the tank has a sufficient amount of suspended particulate matter.

Reproduction

Tube Worms can reproduce both sexually and asexually. In sexual reproduction, they release gametes into the water column, where fertilization occurs. Asexual reproduction happens through budding or fragmentation of the tube, leading to the growth of new individuals.

Symbiosis

While Filograna implexa does not have any well-known symbiotic relationships in the aquarium setting, their presence can contribute to the overall biodiversity and balance of a reef tank ecosystem.

Habitat

Filograna implexa is typically found in shallow marine environments, often attaching to hard substrates such as rocks, shells, or coral skeletons. They are widespread in various oceanic regions, indicating their adaptability to different marine conditions.
