She gets this hard gunk build up in the back corners of her lips, the space that allows her mouth to stretch. I looked into her mouth she has no redness or lesions like with mouth rot. But there's this, its really hard and doesn't just come off. It feels almost like a hard scan. She has no other signs like yellow fungus. If I open her mouth its only in the corners. She eats and poops fine. Her basking is 100 cool side is 85 she has a regular basking bulb with a solid surface to bask. She has a uvb t5ho inside the enclosure.
