Common name: Pillar Tailed Flatworm

Scientific name: Stylochus pilidium (Goette, 1881)

General information

Stylochus pilidium, commonly known as the Pillar Tailed Flatworm, is a species of marine flatworm belonging to the family Stylochidae. These flatworms are known for their elongated bodies and distinctive color patterns, which often feature a combination of brown, white, and sometimes iridescent blue hues. They are not commonly found in the aquarium trade but can be interesting subjects for dedicated invertebrate enthusiasts or those with a focus on biodiversity.

Care

Pillar Tailed Flatworms are not demanding in terms of care, but they do require a stable and mature marine aquarium with a well-established microfauna population. They are typically found on or near the substrate, where they feed on small invertebrates and detritus. It's important to maintain good water quality and avoid sudden changes in water parameters to ensure their well-being.

Reproduction

Reproduction in Stylochus pilidium is not well-documented in the aquarium setting. However, like many flatworms, they are likely capable of both sexual and asexual reproduction. In the wild, flatworms can reproduce by fission, where the organism splits into two, or through the laying of eggs.

Symbiosis

There are no notable symbiotic relationships involving Stylochus pilidium that are of particular interest to the aquarium hobby. However, their role in the ecosystem as part of the clean-up crew, consuming detritus and small invertebrates, can be beneficial to the overall health of the aquarium.

Habitat

In their natural habitat, Pillar Tailed Flatworms are found in tropical and subtropical oceans, often associated with coral reefs, rocky substrates, or seagrass beds. They are benthic creatures, meaning they live on or near the bottom of the ocean.
