So recently got a white tail tang(so pretty) and didn't have a big enough Qt for them so decided to roll the dice on health... And as one night guess by this post, it turns out she had something. She's already in hospital (said original 20 small tank) with copper and improving already, but I'm about to start pulling rest of the fish out of the DT. Question is... Ich or Velvet. I had a grandma Gramma who I've had for 5 or six years get something similar then it all went away a few days ago and he's right as rain at moment. Initially I thought velvet so I had an all(most) night hospital tank setup run. But I don't know. I would very much appreciate the collectives opinion. Image attached.
