UGH THANK YOU SO MUCH FOR POSTING THIS!
I bought a BP at a pet store last month with the same thing Ive been worried that it was something contagious.
By any chance would this give the snake a bad disposition? The reason I ask is mine will strike any time you reach in the tank or sometimes go near it. There is nothing else that I can see wrong with her aside from whomever dropped her off at the pet store didnt take care of her and she has some very nasty scar tissue.
