Those are redbugs. You can completely see the yellow body and the dark spot which would be red. The acro in the picture is not dead due to the polyp extension.
Honestly, I zoomed way in on the photo and I don't think there are any red bugs on it. Red bugs would stick out like a sore thumb, on that white skeleton. While Red bugs can be difficult to see, on a healthy coral, you'd see the red/yellow demons easily, on a bare skeleton. Even with a healthy coral and a good photograph, they're easy to see, once you know what to look for.. Red bugs do not cause STN.
