I got my first BP on 7/12/15. I let her be, in her new environment all week, fed her on 7/18/15 (successful switch to F/T), handled her for the first time last night 7/21/15. I wasn't sure if this was something to be alarmed about but I figured getting some expertise from the members here couldn't hurt! I noticed a very small dark spot on her mouth, unfortunately I cant compare it to the day I got her because I didn't handle her I just put her in the tank to let her get acclimated. I read up on "mouth rot" and it got me a little nervous that it could be this but I don't know how she would have got it unless it was from feeding live (dirty mouse?) prior to my pickup? Below, the first picture of her face on the right side of her mouth you can see a very small dark spot. The other pics are just for viewing pleasure
