Found another urchin today, this one looks like a rock boring urchin. It's just crazy that I bought this live rock 10 months ago, the tank sits on my desk where I am for hours a day, and this is the first time I'm seeing this urchin. I guess they hitchhike as tiny eggs or larvae and are probably microscopic for weeks or months.
