Frogspawn expelling mesenterial filaments

[CronicReefer]

So my frogspawn started shedding yesterday and has been closed up since. I looked today and noticed that there is a small patch of mesenterial filaments coming out from where the polyps attach to the skeleton. The frogspawn sits by itself on top of a rock so it has no neighboring coral to cause this reaction. All water parameters are normal and none of my other corals are showing any ill effects. I did a WC last Thursday and I fed the frogspawn some LRS reef frenzy on friday. I have been vodka dosing for the past 3 weeks so this is the only thing I can think of as the possible source of the problem. Just wondering what other possibilities may cause this to happen or if this is something normal.
