Red Urchin

Red Urchins are striking, spiky invertebrates that bring dynamic movement and natural cleanup power to established reef aquariums. These hardy grazers feed on algae and detritus, helping maintain a balanced ecosystem while adding visual interest to your tank. Care is straightforward for intermediate to advanced aquarists. Red Urchins thrive in stable saltwater conditions with moderate to strong water flow and plenty of rockwork to explore. Maintain temperatures between 72–78°F, stable salinity, and excellent water quality. They're generally peaceful but may graze on desirable coralline algae and soft corals if hungry, so ensure adequate natural food sources. Provide hiding spots and secure décor, as their spines can dislodge unstable structures. These urchins are reef-safe when properly fed and acclimated, making them an excellent addition to mature systems seeking natural biological balance. Their unique behavior and striking appearance make them a favorite among serious hobbyists.
