Sick Foxface: Please help identify and treat

[sptfyre51]

I added a rabbitfish to my 150 gallon FOWL tank a couple of days ago. I didn't notice it the first day, but the second day I saw it had a pink lump on its mouth. Can someone help me identify it as well as know how to best treat it? my water parameters are 0.0 ammonia, 0.0 nitrite and 0.0 nitrate (just finished cycling my tank and did a 100% water change before adding fish).

New member here so don't take word but you might want to search lymphocystis. Rabbitfish seem to be susceptible to this infection Good Luck...

Yes, I was thinking lymphocystis as well, but your pics are not clear enough to tell for sure. Did you notice this suddenly or did the problem just pop up?? Lymphocystis does not just appear overnight to that extent.

Here are pics and info (If you can describe the problem in detail, that would help):
