Common name: Banded Brittle Star

General information

The Banded Brittle Star, Ophionereis schayeri, is a species of brittle star often found in the reef aquarium trade. This invertebrate is known for its distinctive banded pattern on its arms and central disc. Brittle stars are close relatives of starfish but have a more defined central disc and long, flexible arms that they use for locomotion.

Care

Banded Brittle Stars are detritivores, meaning they feed on detritus and organic matter, making them excellent scavengers for the reef aquarium. They are nocturnal and tend to hide during the day under rocks or in crevices. Providing a tank with plenty of live rock and a sandy substrate can mimic their natural habitat and offer hiding places.

Reproduction

Reproduction in brittle stars typically involves the release of eggs and sperm into the water column, where fertilization occurs externally. In the aquarium, this spawning behavior can be observed if conditions are optimal, but raising the larvae to adulthood can be challenging.

Symbiosis

While not known for specific symbiotic relationships like some other marine organisms, brittle stars can contribute to the overall health of the reef by cleaning up excess organic matter and detritus.

Habitat

Ophionereis schayeri is found in a variety of marine environments, from shallow reefs to deeper waters. They are adaptable to a range of conditions but prefer areas with plenty of hiding spots and access to organic material for feeding.
