Spots on corals

[SCReef'n]

Any idea what these spots may be?

The lower ones appear to be sunken polyps. But the upper ones seem to be blotchy tissue

hard for me to see, I can’t really see anything of concern but with the blues and my eyes, u know. See if anyone else may see something.

What kind of fish do you have in the tank? FWIW I had a Bicolor Blenny that became a problem one time. Just got a taste for some of my sps corals I guess. Just rasping away.
