Common name: Starfish

The family Ophidiasteridae is a fascinating group of sea stars (commonly referred to as starfish) that are widely distributed across the world's tropical and subtropical oceans. Known for their vibrant colors and striking patterns, species within this family are highly sought after by reef aquarium enthusiasts. Their body structure typically consists of five arms, although some species may have more, radiating from a central disc. These arms are often slender and elongated, giving them a graceful appearance. The vivid coloration of many Ophidiasteridae species, such as bright reds, oranges, blues, and purples, makes them a visually stunning addition to any marine aquarium.

One of the most popular species within this family is the Linckia laevigata, prized for its brilliant blue hue. These sea stars are not only beautiful but also play a functional role in aquariums by scavenging detritus and algae, helping to maintain a clean environment. However, they require stable water parameters and a mature tank with plenty of live rock to graze on, as they are sensitive to changes in water quality. Hobbyists should also be cautious when handling them, as sea stars are delicate and can suffer from stress or physical damage.

Ophidiasteridae sea stars are echinoderms, meaning they belong to the same phylum as sea urchins and sand dollars. They possess a unique water vascular system that aids in locomotion, feeding, and respiration. These animals are also capable of remarkable regeneration, able to regrow lost arms over time. In the wild, they play an essential ecological role by consuming decaying organic matter and contributing to the health of coral reef ecosystems.

For aquarists, it’s important to research the specific needs of the species within Ophidiasteridae before introducing them to a tank. Some species may have specialized diets or require specific tank mates to thrive. Additionally, they should not be exposed to sudden salinity or temperature changes, as this can lead to health issues. With proper care and attention, these sea stars can be a captivating and beneficial addition to a marine aquarium.
