Common name: Nebulous Terebellid Worm

General information

The Nebulous Terebellid Worm, scientifically known as Eupolymnia nebulosa, is a species of marine polychaete worm belonging to the family Terebellidae. These worms are often referred to as Spaghetti Worms due to their numerous long, slender tentacles that resemble strands of spaghetti. These tentacles are used for feeding and respiration. They are fascinating creatures that can add a unique aspect to a reef aquarium due to their burrowing behavior and distinctive appearance.

Care

Spaghetti Worms are detritivores, meaning they feed on detritus and leftover food particles in the substrate. They are beneficial for the aquarium as they help to clean and aerate the sand bed. These worms require a tank with a deep sand bed and low to moderate water flow. They are generally hardy and can adapt to a range of conditions, but they do best in a stable, mature aquarium.

Reproduction

Reproduction in Eupolymnia nebulosa is not well documented in the aquarium setting. However, like many polychaetes, they are likely to reproduce by releasing gametes into the water column where external fertilization occurs. Hobbyists may occasionally observe small swarms of larvae, indicating successful spawning.

Habitat

Nebulous Terebellid Worms are found in a variety of marine environments, often in sandy or muddy substrates where they can burrow. They are distributed across temperate and tropical seas worldwide. In the aquarium, they will typically bury themselves in the sand bed, with only their tentacles visible as they filter feed.
