Agreed, I've always kept it in close quarters and never had issues.

On occasion I'll loose an inch of montipora to my colony but the dead area quickly becomes grown over again. The only circumstance where you'd really need to worry is with tiny frags placed adjacent to the colony or toppled coral landing on it. But that basically goes for any coral.

The conditions mine is under are: 250W Phoenix 14K DE, moderate flow, 78 F, 1.025, pH 8.1-7.8, Ca 450ppm, Alk 10 DKH, Mg 1400ppm.

Considering that many SPS will grow right into their neighbors and begin warfare at that point I would consider a 1" growth inhibition zone to be fairly large.
