Is something eating my Favia?

[ChaseBurke]

small spots are appearing on it in the last 2 to 3 days. Is it getting eaten or does it just look unhealthy and might need moved?

To get the ball rolling:

I'd keep an eye on the fire shrimp.

Plus one on the shrimp, keep an eye. Could be necrosis as well. Maybe try an iodine based dip if it gets worse.
