Echinometra mathaei – reef roof drilling sea urchin
 The Echinometra mathaei – reef roof drill sea urchin is an excellent algae eater. It likes to eat thread and Caulerpa algae in particular. A useful helper, especially during the initial phase. The sea urchin usually lives directly on the rocks. Like all invertebrates, please always get it used to the aquarium water and move it under water so that no air gets into the animal. This can lead to the death of a sea urchin.
