well after posting i found some info on it another common name is rock urchin(sp.colobocentrotus). they are reef safe ......but they do not do well in a fish tank.book says lives in intertidal shore rocks exposed to heavy surf. the book says they need the heavy surf to live. the waikiki aquarirm has been able to keep them.. but they keep every thing tho.
