Common name: Clam Worm

General Information

The Clam Worm, scientifically known as Nereis vexillosa, is a fascinating polychaete worm often found in intertidal zones and shallow marine environments. Known for their segmented bodies and bristly appearance, these worms are a common sight in tide pools and mudflats, where they play an essential role in the ecosystem as both predators and prey.

Though not as prominent in the aquarium trade as other marine species, Clam Worms are occasionally used by hobbyists as live food for fish and invertebrates due to their high nutritional value. They are also studied for their unique regenerative abilities and complex behaviors.

Care

While not typically kept as pets, Clam Worms can be maintained in a marine aquarium with a substrate of sand or mud, mimicking their natural habitat. They require a stable environment with clean, well-oxygenated water. These worms are relatively low-maintenance but need an environment that allows them to burrow and forage.

Diet and Feeding

Clam Worms are omnivorous, feeding on a variety of organic materials, including detritus, small invertebrates, and algae. In captivity, they can be fed a diet of finely chopped seafood, algae wafers, and detritus. Providing a diverse diet will ensure they receive all necessary nutrients.

Behavior and Compatibility

Clam Worms are generally peaceful and can be kept with other non-aggressive marine species. They spend much of their time burrowing in the substrate, emerging to feed. Their presence can help aerate the substrate and contribute to the overall health of the aquarium environment.

Health and Common Issues

Clam Worms are hardy and can thrive in a well-maintained marine aquarium. However, they are sensitive to changes in water quality and require stable conditions to prevent stress or disease. Regular monitoring of water parameters and maintaining a clean environment are crucial for their health.

Habitat

Nereis vexillosa is found along the Pacific coast of North America, from Alaska to California. They inhabit intertidal zones, mudflats, and sandy areas, where they can burrow and forage. These environments are characterized by varying salinity and temperature, which the worms have adapted to withstand.
