Anyone have a recommendation for a reef safe urchin that'll eat coralline off rocks and glass? I had a tuxedo urchin in the past and my tank never had coralline in it (not sure if it was a coincidence or if it did eat the coralline).
I heard somewhere that the tuxedo urchin would do it, but the shortspine urchin was really known for going to town.
