Achillies tang help

[szl]

Hello all.

I have an achillies tang in qt right now. He's been doing great until I just noticed a largish white spot on the top of his head. Is it possible that he is bumping his head on the top of a piece of PVC he hides in?

He is still eating alot water chemistry is good. I'm attaching a pic to help out.

Hard to tell from the picture. Did it show up suddenly? How long have you had the AT?

Turns out it was just him bumping his head on the top of PVC. I flipped it upright and with in a couple of days the spot was healed.

Now if I can just get my yellow tang to not go absolutely berserk on him
