Common name: serpent star

General information

The Common Brittle Star, Ophiura ophiura, is a species of brittle star often found in the marine aquarium trade. These echinoderms are known for their distinct central disc and long, slender arms which they use for locomotion. Brittle stars are scavengers and detritivores, playing a crucial role in the cleanup crew of a reef tank by consuming leftover food and organic waste.

Care

Brittle stars are relatively easy to care for and can be a great addition to a community tank. They thrive in tanks with plenty of live rock and a sandy substrate that allows them to hide and search for food. It's important to ensure that the tank is well-cycled and has stable water parameters to keep these invertebrates healthy. They are sensitive to rapid changes in water conditions, so gradual acclimation is crucial when introducing them to a new tank.

Reproduction

In the wild, Ophiura ophiura reproduces both sexually and asexually. In an aquarium setting, sexual reproduction is less common, but they can reproduce asexually through fragmentation, where a part of an arm and the central disc can develop into a new individual.

Habitat

Common Brittle Stars are found in a variety of marine environments, from shallow coastal areas to deeper waters. They are particularly common in areas with sandy or muddy substrates where they can easily burrow and find food. In the aquarium, they require similar conditions with plenty of hiding places and a stable environment.
