Orange shoulder problem

[mejiamale]

Need some help reefers. Came home to this on my fish. What is it and what do I do? 8-9inch orange shoulder tang. What am I looking at?

Do you have any new additions to your tank? Anything wet that wasn’t QT’ed?

Do you have any aggression in your tank? It could be that the fish got into a coral or rock and injured itself.

It doesn't necessarily look parasitic from what I can see.

At any rate a bath in acriflavine (Ruby Reef Rally) or methalyne blue would be a good place to start.

Nothing in months. No aggression.
