Yellow Tang blotchy skin?

[Spar]

I have a couple yellow tang's in QT that have blotchy skin. I completed TTM about 4 days ago and have done one round of PraziPro so far; no meds other than that.

Any idea what this might be? Could it just be stress induced blotches?

There are also more than usual prominent lines across one.

Not sure about the blotches, but the top photo looks like the beginning stages of HLLE.

ya i noticed that also. they came like that though. i've been good at keeping them well fed and good water quality, so hopefully turns around. they are energetic and eat well, so is at least a good sign.

They are in good hands.
