Red Pincushion Urchin

Salmacis Urchins generally inhabit reef rock and rubble areas covered in algae. These urchins are primarily herbivores, feeding on algae and other plant material found on rocks and substrates. Urchins may disturb substrate and other tank inhabitants. It's essential to avoid using copper-based treatments in a tank with sea urchins, as it can harm them. Always follow the recommended guidelines for medication use in marine aquariums.
