Can someone diagnose this?

I’m pretty sure it’s ich, my blue tang has had it for like 3:4 weeks I’ve done a copper treatment - probably done it wrong. Did a tank transfer method on all the fish - probably done it wrong. Now my blue tang after few days of being clear looks like this.

is this defiantly ich? And why does it keep going to my yellow tang and foxface and just stand in front of them and float as if to say here take some ich.?

also what is the damage on the face of the blue tang? Is it from all the scratching and flashing

This is the link of the blue tang just getting in the way of everyone I don’t know why it’s honestly like he wants everyone to get it aswell

Hmmm....it looks more like flukes than ich to me. Any way we can get a more in depth shot of the fish? Right now, it's a bit too far away for me to identify if those look more like salt crystals or more like blotches.

The damage to the front part can be early HLLE, or it can just be the tang being the tang...
