Common name: banded ophiocoma
General information
The Dwarf Brittle Star, Ophiocoma pumila, is a small and agile echinoderm that is popular among reef aquarium enthusiasts. This species is known for its distinctive banded arms and central disc, which can exhibit a range of colors from brown to reddish or even greenish hues. Brittle stars are nocturnal and tend to hide during the day under rocks or within the crevices of the reef.

Care
Ophiocoma pumila is a hardy species that can adapt to a variety of tank conditions. They are excellent scavengers and will help maintain a clean aquarium by consuming detritus, uneaten food, and dead organisms. It is important to provide them with plenty of hiding places and a stable environment with consistent water parameters.
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 present.
Symbiosis
While not known for specific symbiotic relationships like those seen in clownfish and anemones, brittle stars can contribute to the overall health of the reef by providing cleaning services and aiding in the breakdown of organic matter.
Habitat
Dwarf Brittle Stars are typically found in shallow reef environments where they can easily access organic debris for feeding. They are adept at navigating the complex structures of coral reefs and are an important part of the ecosystem.
