Trachyphyllia white fuzz coming out with color pigments

[eislekel]

I bought my Trachyphyllia 2 days ago, and white fuzz coming out from the skin with its color on it.
My water parameters are normal.
Is there anything that I can do? Is it normal?

Water parameters:
Salinity: 1.025
KH/Alk 8
MG: 1200
Nitrate: 0.5
Calcium 400
Phosphate: 0

Just look like slime to me, Normal symptom of stress should go away after he’s acclimated and happy.

Today morning, I realized some white spongy things (it doesn't look like Mesenterial Filaments) on my coral as well.
Do you know what causes that?

Sorry for double post.
It looks like Mesenterial filaments. I think something went through. Maybe snail or bristle worm.
