Ophiocoma sp.

Datasheet

General DescriptionThe Brittle Sea Star, scientifically known as Ophiocoma sp., is a common sight throughout the Caribbean waters. It features a small red central disc that may display varying patterns, with its long spiny arms adorned with white spines and patterns. This nocturnal species tends to seek refuge under rocks during the day and emerges at night to feed on detritus, leftover food, and small organisms. Brittle Sea Stars should not be exposed to copper-based medications and are highly sensitive to sudden changes in water parameters, including oxygen levels, salinity, and pH.

Aquarium SuitabilityBrittle Sea Stars are generally suitable for aquariums, provided that their specific care requirements are met. They are semi-aggressive in temperament and are compatible with reef environments. However, due to their sensitivity to water chemistry changes, drip acclimation is crucial when introducing them to a new tank.

Care and HardinessThe care level for Brittle Sea Stars is considered moderate, requiring a varied diet that includes frozen mysis and brine shrimp, as well as finely chopped shrimp and mussels as supplements. Additionally, maintaining stable water conditions with a pH range of 8.1-8.4, a salinity level of 1.020-1.025, and a carbonate hardness (KH) of 8-12 is essential for their well-being. Trace elements should also be provided regularly to support their health.

Reef SuitabilityThis species is reef compatible, making it a suitable addition to reef aquariums. Their omnivorous diet and semi-aggressive temperament allow them to thrive in a reef environment without posing a threat to coral or other tank mates.

Aquarium SetupWhen setting up an aquarium for Brittle Sea Stars, ensure that there are plenty of hiding spots such as rocks and crevices where they can seek shelter during the day. A sandy substrate mimics their natural habitat and allows them to forage effectively. Maintaining stable water parameters and providing a well-rounded diet are key factors in creating a suitable environment for these sea stars.

BehaviourBrittle Sea Stars are primarily nocturnal creatures and exhibit semi-aggressive behavior. They are known to scavenge for food in the dark, utilizing their long, spiny arms to navigate and feed on small organisms and organic matter. Caution should be exercised when handling them, as they are fragile and should not be exposed to air.

Feeding and DietTheir omnivorous diet consists of frozen mysis and brine shrimp, supplemented with finely chopped shrimp and mussels to ensure proper nutrition. Offering a diverse range of food items helps maintain their health and vitality in a captive environment.

Habitat and DistributionFound predominantly in the Caribbean region, Brittle Sea Stars inhabit shallow coastal waters where they can hide under rocks and sift through sand for food. Their striking red coloration with white spines and patterns makes them a visually appealing addition to marine ecosystems.
