Frogspawn Head Shriveled Up

Anyone had this happen before? One of the five heads of my frogspawn suddenly deflated yesterday and still is deflated today. The other heads are slightly less puffy than normal as well. Water parameters as of today:

Alk: 8.3
Calcium: 465
Mag: 1290
PO4: 0.13
NO3: 13.6
Temp: 80.8
Salinity: 1.026

Planning to do my normal 20% water change later today, so that will bring the PO4 and NO3 down to slightly more ideal numbers. They’re just a hair higher than what I like to run.

I also had a clear frag rack shading the frogspawn for a few weeks and recently moved it. So maybe this is a light-related response?

One other thing to add. My clownfish often host in the frogspawn, so it may be as simple as a physical injury to that polyp.

Do any other corals show signs like this?

No, everything else is doing great. I’m really leaning toward this being physical trauma to the polyp caused by one of the clownfish. Also noticed some black spots on one of the clowns which is a sign of being stung by LPS.
