Royal Urchin is a reef safe urchin. They are excellent algae eaters. As you can see by the photo, they are collectors due to their sticky spines, often has litle rocks, etc stuck to them. These guys are not bulldozers like some urchins can be.
They generally come in two different colors: blue body with red spines and blue body with blue spines. We will ship what we have available. Special color requests can be made, but is subject to current stock.
