Hello. I purchased my water dragon about 8 months ago. He was incredibly young and he's grown into a colorful young man. However, this swelling started forming on the sides of his mouth. I am really concerned and not sure how to treat it. It's not bloody but dry. He rubs his nose a lot against the glass. I've tried so many solutions, but hes just too used to being out on my shoulder. Any ideas on what this on his mouth could be and any suggestions for the glass dancing?
