What's going on with my Yellow Tang?

[ZoWhat]

Forgive the crude pic quality.... shot at a distance with blue light.

Ive never seen this before, What in the world? IT SHOWED UP IN 1 DAY

The only thing I've noticed is my Stripped Squirrelfish has been VERY territorial this past week.....Yet tonight I've seen them both swim and hangout close to one another, weird!

Fight? Scrap against rocks? Bacterial? Parasite?

Its eating ok. I lil shy coming out. No territorial fights that I have notice

Is it missing “flesh” as it appears? If so it’s probably damage if it happened in the matter of a day. I’m not sure what could inflict such damage but it’s likey to become infected.

This poor fish I named Apostale Paul..... bc when I was dosing Lugols Iodine like 6mos ago...I overdosed to where this Yellow was actually BLIND for a number of days....Yellows sight returned a few days later after stopping Lugols

(In the Bible Apostale Paul was blinded for 3 days on the road to Damascus)

We'll see if Apostale Paul has one more miracle up his sleeve.
