Six line wrasse something on its head

[Theulli]

Hello!

see the photo - the wrasse is new to the tank, and a damsel has been picking on him a bit, so it is a bit stressed, probably related. It has a whitish/nearly translucent line on its head that appears to be bothering it - it twitches frequently. The line does not appear fully attached to the fish, I can see parts of it waving in the water occasionally. You can see it hopefully in the attached pic. Any ideas? It is right above the far eye



It is eating like a champion and moving around the tank

Maybe a fluke?

I am doing a FW dip and the thing looks super obvious now

It turned white, I blew it off with a eye dropper, here it is under a microscope

That looks like the spitting image of a fluke, thanks for nudging me in the right direction! Now to decide if I should dose prazipro into the tank or wait to see if other fish pick it up…
