Managing Encrusting SPS (and other corals)

[FuzzySPS]

If dedicating a small to medium sized rock to an encrusting coral and to prevent further encrustation over neighboring corals would the following idea work?:

relocate the rock away from other rock to the sand (or bare bottom) after first drilling its bottom and using epoxy to secure some acrylic rods thereby creating what are effectively very short stilts (this assumes of course that the light and flow requirements would be met after being relocated to the tank floor). My thought is that when the encrustation grows down and around the bottom of the rock it would eventually be totally shaded and stop any further coral growth. Is there any merit to this and, if so, would it also work for soft corals such as star polyps and zoas (though I think they can spread by releasing themselves and allowing the current to allow them to find a new home but not totally sure about this).

Any thoughts or alternate ideas?

Did you ever find the answer to your question? I don't think you can stop encrusting corals from spreading, eventually, if two different species are growing close to each other, they will fight for the spot.
