What is wrong with FAVIA coral?

[Oliver94]

Hey guys! I hope you are having a great week.I have a problem regarding my favia coral...Few days ago I found these holes in it (they were on the back side of it I didn't see them before) So to keep an eye on the coral I place it on the sand to check it everyday if something new appears.This morning I noticed new stuff on the coral : I have white grains(salt grain size) of tissue on my colony in different location,At first I thought It was dirt I try to remove them but it is from the coral,attached.. any idea what this is? I dipped it 2 days ago when I noticed the holesHere are some pictures of the holes and the white stuff on it: herbergeur d image hebergement d image hébergement gratuit Parameters: PO4: 0NO3: 10pH : 8 Thank you in advanced!

Sounds like feeder tentacles. Your pix links still did not work, but they may not be needed now. Glad it was nothing serious.
