Frogspawn peeling?

[ATC]

I’m still really new at this so forgive me if I sound stupid but While I was feeding this morning I noticed my frogspawn looks like one of the heads is peeling it’s been in the tank for over three months and was actually doing really well it even grew a new head. Also have some weird looking spots on the bottom that I just noticed today hoped I’m just being paranoid. Normally it is open and full. And it’s only one of the 3 heads doing it
Every other coral in the tank is doing really well.

water parameters as of last night are as follows
Nitrite 0
Nitrate 15ppm
Kh 10.5 dkh
Amonia 0
Ph 8.4
Calcium 400 ppm
Magnesium 1250
Phosphate .02 I think only test I’ve got is a fluval and it’s really difficult to read.

Looks like what is known as polyp bailout. It’s due to stress and often caused by too much water flow, light or both.
While hammer is not finicky about location, assure the polyps are not dancing in the current or bent to one side
Also calcium should not be less than 380

Somebody “taste” that head?
looks very clean to me.

I guess it’s possible I don’t know who would have done it other than maybe the cleaner shrimp or one of the hermits. I’ve never seen any of the fish go near any of the corals. And I didn’t see anyone do it and there has been no other changes or additions to the tank in over 2 months I did have a slight battle with getting my kh in check last month but it never went below 9 dkh. It was super happy yesterday and today here we are. Anything I can do to help it make it through. Also anyone know what the little dark spots are at the base?

Watch that shrimp.
Corals don’t usually go “poof” overnight, especially when the rest of it looks great.

I was wondering about those too. Are they hard? Do they move?

.02 PO4 is kinda low maybe part of the cause. Hobby test kits have a bit of margin for error.. so .02 could really be 0 .. or more. More would be ok in this instance, as 0 is not good. Strong flow from the same direction without some change can also cause it to lift off on one side.

What you have circled looks like nudibranchs ( similar to lettuce) remove them to be safe. That im on full screen there is separation from skeleton. Not sure how old this tank is but this coral species isn’t terribly picky when it comes to the proper placement in your tank. The trick would really be just to avoid the extremes. Avoid extremely bright locations or areas of very high current, and avoid areas that are too dark or with currents that are too low. Fast currents risk damaging the soft, fleshy polyps (and getting an infection). Bright lights will cause bleaching. Insufficient lighting will cause the poor coral to wither away and starve to death.
Hammer corals only require a moderate amount of light for photosynthesis and can grow well in the intermediate regions of your tank. Just about any reef LED lighting should be sufficient for most tanks. Reduce white light intensity and get it off the sand bed which sand can irritate it.
The polyps should sway in the current, but not sustain so much pressure they are constantly bent over their skeleton. Too much flow will tear the polyps (worst case) and cause the polyps do not extend in the first place (best case). So, don’t give them too much flow.
