Yeah, looks like HLLE
, which my yellow tang was developing before I started feeding him nori (its much improved now). Except in mine, and the pics I've seen, its usually behind the eyes, and along the front of the gills, then with spots along the lateral sensory line.
could be a side effect of an ich infestation.
Copper can be bad for tangs, so hypo is probably the best way to go. I need to get a refractor in case I ever find myself in this situation.
