My sps has holes on it

[megs_clark]

its at the base and a bit up the stake of the sps. Its normal color is kind of a purply green when healthy, but the areas where i see the holes are going all green, and the rest all purple lately. i think the tissue is dying in the green parts. Ill try to take a picture. I thought they were polyp holes, but then i notices theirs tons where its dying and not where its still healthy? Ill get the pics up asap
