What would cause a bare spot like this on my SPS?

Looks like a bite mark, I would check for Red bugs/ AEFW just to be sure you don't have an infestation. You never think it can happen to you but it Does.

There is something going on. I just looked at my Plum Crazy and saw this. This has happened on my Plum Crazy before and also my red planet, and I left both alone, and both came back and covered back over with flesh and looked fine. Hopefully it will again, but something is causing this. I have taken out a magnifying glass and flashlight and can find nothing.

that second pic looks similar to aefw bites.
you CANNOT see them when they are on the coral, they eat the zooxanthelle and blend in with the flesh... pull the coral out and look closely at the white spots if you can, does it look like its down to the skeleton or just like there is no color left in the flesh? In my experience AEFW do not eat through to the skeleton.
another option is to toss one in some revive or coralRX and see if any flatworms come off

do you have any lps like frogspawn in the tank? mine used to drop pieces of itself and then they would hit an sps and kill that lil spot.
keep an eye on those sps if it keeps spreading you might want to check your water and do some changes... dont think they are AEFW bare spots like that are different looks like it got burnt or stung by something to me kinda wierd

my thoughts exactly.. if there is no tissue just skeleton then something bigger than your average acro pest hit it or bit it in those spots, or its just dieing off.. Im not sure how hesitant you are to frag a branch off, but it might not be a bad idea for redundancy's sake.

I had a bi-color blenny that was biting the snot out of the bases of just 2 acros in the tank. I noticed wite marks. No alk burn. Water great. PE great. Growth and colors decent. No parasites. One day I was sitting there and the little bleepdity bleep swam across to where these two corals were and start biting on the bases. He's in the softy and LPS tank now. Hopefully it's a fish and not a bacterial infection or a really bad swing that has started a runaway melt down of your corals.
Just felt like sharing story of my unexpected problem fish.

I do have a black comb tooth blenny. Also, I added a Bellus Angel a few days ago, but they are supposed to be reef safe. And I have noticed this problem before the Angel went in. Could be the Blenny. I will watch him.

All blennys and Angels can eat your SPS. Mine did :-/

After doing some Google searching, it looked like some people were having issues with some blennies nipping SPS, with one guy saying his bi-color stripped some of his SPS bare. So I caught mine and put him in my frag tank for the time being. I'll see if the SPS heal up and if there is no more damage, then I will at least know if it is him or not.
