When I purchased my live rock I knowingly inherited this urchin. What I did not know was that there was a baby urchin, about the size of a dime, also lurking in the rock.
These two guys have done a pretty good job on getting my algae under control but they buldoze my corals. So at least one of these has to go so that I can add more coral. Their body is about the size of a golf ball. Spines included they are a bit smaller than a tennis ball.
I am not keen on shipping. Anyone in the Okanagan interested?
