I have an orange spine pincushion urchin (Tripneustes Gratilla)that eats all kinds of algaes and has not touched any of the softies I keep (dont know about stoneys-as I have none at this time). He will stay small 2-3 inches. He can be a bit of a bulldozer though so one would have to secure the corals/rock well. I have heard that the Tuxedo urchins (Mespilia Globulus) also work well in reefs.
