ID skin condition on Royal Gramma

Can anyone identify this skin condition on my Royal Gramma

Could he have scraped himself badly on a rock? Does he live in a hidey hole inside of a rock??

I've had these guys wedge themselves in rocks often especially on introduction which can lead to stuff like this. Does look like a lot of scrapes scales. Any aggressive tank mates?

After consulting with Biota and reef2reef I purchased six Gramma from a single tank of theirs. Initially no one expressed any concerns. Apparently life is much different in a tank with lots of rock for fish to create territories than in a grow out tank with only PVC. As someone later commented I believe adding six Royal Grammas created a "Royal Rumble". Another learning experience at the expense of my fish.

Does look like he scratched himself, I had a flasher wrasse that did the same once, they recover but takes several months.
