Tomini Tang White Patches?

[Miketc17]

I’ve had this Tomini for two weeks now. It hasn’t touched the veggie clip since day one. But it is constantly grazing on the rocks and eats mysis like a pig. Yesterday and today it didn’t eat mysis and I feel like she’s not grazing as much. I soak my food in garlic and selcon. About a week ago I noticed an odd faded white spot on both her sides but didn’t think much about it. One side cleared up and the other side is still there (you can see in the video). But today I noticed a couple of these same white spots/patches under her chin and almost like a scratch on her nose. Any idea what this could be? She’s always darting around like crazy through rock and coral so I always thought they were just scratches or coral stings. But the lose of appetite now has me worried. Thank you so much in advance!
