Get a captive clone, and use some sense when you place it. Experience helps here, but they like a nice hole to sink their foot into.
No guarantees, but captive roses usually don't wander. Some individuals of the wild variety don't like to be hammered with halides, others don't mind. Again, this variation is minimized with captives.
Having said this, an SPS tank isn't the best place for one. They can get big, and even if they don't move, they might still end up stinging your corals eventualy.
