"Bubble" on Hippo Tang

I just bought a Hippo Tang a couple days ago. It is flying around my tank and eating like a pig. But, I just noticed that it has a "bubble" on its lower back tail fins.
Does anyone know what this might be and how to treat it?
Thank you.
 
I'm following. Mine had a very small dot on its fin and it eventually turned into a small little bubble. Stayed for a few days and fell off I guess. Still dont know what it was but seemed to have no effect on the fish.
