Can anyone ID this please

That is perfect. I have a 2.5 gallon painted black on all sides but one to use for photos and freshwater dips.

What actually led to the vet getting a diagnosis?

Just by re-examining the fish again and finding no other parasites.

So I guess not concrete evidence, but process of elimination and educated guess by the vet. The vet said more than likely it was a fish herpes.
