Reef safe urchin that eats coralline off rocks and glass?

[kinetic]

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.

Purple-spine urchins from Florida devour coralline algae; I wish they didn't scrape all of it off. Also can scrape insulation off of circ pump cables in the water if you don't wrap them with coil wrap.

I haven't seen these before, it's not this one is it?

Many of them do to a point. If you are looking for something to actually keep things clean, you are going to be dissapointed!
