Marine Sea Urchin • Algae Control Grazer • Rockwork Sculptor • Reef-Safe Invertebrate
 
📋 The Rock-Boring Urchin (Echinometra mathaei) is a hardy marine echinoderm known for its ability to graze algae and create small burrows within rock surfaces.
In reef aquariums, it serves as a Powerful Algae Grazing Specialist, helping control coralline and nuisance algae growth.
This species uses its strong mouthparts (Aristotle’s lantern) to scrape algae and gradually form shallow indentations in rockwork.
With stable water parameters and adequate rock structure, it thrives as a Natural Reef Maintenance Invertebrate in marine systems.
