Strange mark on my wrasse

Just got home from work and found this mark on my wrasse that wasn't there last night. I added a magnificent foxface to the DT Saturday. Any chance it is from a run in with him or is it something else?

Hard to tell from the photo but appears to be missing a scale. I've had wrasses look fine one night and then look beat up the next morning. Might have scratched itself when nestled in the rock work and in its mucus cocoon. I would just monitor it and make sure it keeps eating. If you suspect the FF, keep an eye out for any aggression.

I haven't seen any aggression between those 2 at all but I'll keep an eye out.
