Yikes. What's wrong with my fish?

Lots of possibilities here.

I wonder if that's what happened with the Koran angel at my store. During that time there were 3 other fish with what I believe was velvet (my manager doesn't believe me, he thinks anything spotty is ich ). I only noticed some spots on the Angel for a day then they disappeared and it got all blotchy and pale, then died a couple days later. I've been tiring to figure out ever since then if the Angel had velvet and a bacterial infection, or if it was some odd expression of velvet.

P.S. OP sorry for going off-topic! Not meaning to derail your thread, and whatever is going on with your tang I hope he gets better for you!

Sounds velvet-esque to me
