Common name: Brittle Star

General information

The Brittle Star, specifically Ophionereis porrecta, is a fascinating echinoderm that is often overlooked in the reefkeeping hobby. This species is known for its long, slender arms and central disc, which it uses for locomotion and feeding. Brittle stars are nocturnal creatures, hiding during the day and emerging at night to scavenge for food.

Care

Ophionereis porrecta is a hardy species that can adapt to a range of conditions found in captive environments. They require a tank with plenty of live rock and a sandy substrate to mimic their natural habitat. Brittle stars are scavengers, so they will feed on detritus, uneaten food, and small organisms within the aquarium. It's important to ensure that the tank is well-established with a stable microfauna population to support their dietary needs.

Reproduction

In the wild, brittle stars often reproduce by releasing eggs and sperm into the water column, a process known as broadcast spawning. In the aquarium, however, reproduction is less common but can occur if the environment is stable and there are multiple individuals to increase the chances of successful fertilization.

Habitat

Ophionereis porrecta is typically found in shallow waters, often under rocks or within the crevices of coral reefs. They are distributed across various regions, including the Indo-Pacific. In the aquarium, they appreciate a setup that provides numerous hiding places and a stable environment.
