			 It's an Echinometra mathaei. Common burrowing urchin or boring urchin. They tend to come in as tiny juveniles in corals etc. Then they grow out in your tank.

			 I don't know what you guys are talking about.  That urchin doesn't look boring at all.  It looks quite exciting to me.

			 Do they have a symbiotic relationship in the wild? I'll have to look into that. Seems like he'll be hiding in the rock a lot. I added a piece into the frag tank and he went right to it and burrowed
