Hi I found this guy in my 90 gallon reef that has been going for over a year and a half. I started with all dry rock and I'm really careful of introducing anything into my tank. I do have a pincushion urchin but he is all white and this thing is black. I believe he is a Is rock boring urchin but need to be sure. I have never seen any sign of him except for last night. Thank you for your help
