Black stuff on mouth. Dry nose

Couldn't be poop. That is the one thing my sister is good at. Cleaning it up. I have NEVER seen a single poop/urate in his tank. I will tell her about that stuff though to be sure he doesn't get bacteria in his mouth or whatever.

:) Chlorhexidine is a great solution if it is just gunk.

If not, I have never seen that on a BP that didn't actually already have those markings permanantly fixated.. :confused:

Vet would be able to determine for sure.

Well it is coming off just by a fingernail so it has to be gunk. I'm going to tell my sister a vet visit is the best thing she can do right now. Thanks for the help.
