What is this slime coming off my foxface??

[mikeyfish]

I just noticed tonight that there is a mucus slime coming off my Foxface!! I have him about 2 weeks. He is in my 55 gallon tank with 2 small False percs. The water par are great Amm 0 nitrites 0 nitrates 10 ph 8.2. He is eating and swims well. It looks gross and I'm quite worried. Does anyone have this problem with this fish before??
Thank you
Michael

I second Terry. Do a HUGE water change. My foxface did this and I didnt do a big enough water change sooner He did pass.
