Has anyone ever seen this swollen lip before?! It just showed up over night? One of my older convicts has really swollen lips it's only on one side though the other side has not started to swell, he was fine when I checked them all last night before bed. He's not acting sick or anything an is still eating fine he's not showing any other signs of illness that I can see either. Every thing with the water is testing great so it's not the water quality? I don't know what it could be I can hardly find anything when I look it up. If anyone knows anything about this let me know please!
