Common name: slimy brittle star

General information

The Brittle Star, scientifically known as Ophiomyxa flaccida, is a species of echinoderm that is often found in reef aquariums. These invertebrates are known for their long, slender arms which they use for locomotion and scavenging for food. Brittle stars are nocturnal creatures, hiding during the day and emerging at night to feed.

Care

Ophiomyxa flaccida is relatively easy to care for in a reef aquarium. They require a tank with plenty of live rock and a sandy substrate where they can hide and search for detritus and uneaten food. They are sensitive to changes in water quality, so maintaining stable parameters is crucial. Brittle stars are generally peaceful and can coexist with a wide variety of tank mates.

Reproduction

Brittle stars are capable of both sexual and asexual reproduction. In the aquarium, they often reproduce by releasing gametes into the water column, where fertilization occurs. Hobbyists may occasionally find tiny brittle stars in their tank, indicating successful reproduction.

Symbiosis

Some species of brittle stars have interesting symbiotic relationships with other marine organisms. For example, they may inhabit the same burrows as certain shrimp or fish, or live commensally with corals or sponges. However, Ophiomyxa flaccida does not have any well-known symbiotic relationships that are of particular interest to hobbyists.

Habitat

In the wild, Ophiomyxa flaccida can be found in a variety of marine environments, from shallow reefs to deeper waters. They are often associated with sandy bottoms or rubble areas where they can easily burrow and hide.
