You already posted 2 emergency threads on this same issues on Saturday. This is not an emergency and a 3rd repeat post isn't particularly helpful when you already have responses in the other 2 threads. I would refer to those so we aren't wasting time repeating what others have already said.

Test your water, ammonia, nitrates, nitrites, phosphate, salinity, alk, calcium, everything

This is stress and tissue recession from stress. Often caused from too much water flow, high phosphate, high salinity and even too much bright light. If youve seen them what looks like pooping, it may be expelling zooxanthellae from too much light.
Important also is calcium for skeletal health. If calcium is below 380-400, may also have impact. . . some things to check
