Astropyga radiata | S

Astropyga radiata, known as the Red Fire Urchin, is a visually stunning sea urchin species prized for its vibrant red spines and unique patterning. This small-sized urchin is a popular choice for marine aquarium enthusiasts seeking a natural algae grazer that also adds dynamic movement and colour to reef tanks.

Care and Husbandry: Astropyga radiata requires a well-established marine aquarium with stable water parameters. It thrives in tanks with moderate to strong water flow and benefits from a varied diet including algae, detritus, and supplemental feeding with seaweed or specialised invertebrate foods. Regular feeding is recommended to maintain health, especially in aquariums with limited natural algae growth.

Compatibility and Reef Safety: This species is generally reef safe, posing no threat to corals or sessile invertebrates. However, care should be taken when housing with aggressive fish or invertebrates that may harm the urchin. It is compatible with most peaceful reef inhabitants.

Placement: Provide ample rockwork and crevices for hiding and grazing. The urchin prefers shaded or dimly lit areas but can adapt to various lighting conditions.

Additional Notes: Handle with care due to sharp spines. Ensure the aquarium is mature and stable before introducing this species to avoid stress and mortality.
