Changed his substrate (repti somethin) wasnt cedar or pine but slightly scented. the first day he got a big dirt clot in his mouth on the right side. I noticed a few days later when handling him that it was still there. I cleaned it out, big peice, lots of mucos, and he opened his mouth a few times and went about it. Today when feeding him and noticed theres mucos still. A little hole through it where his tongue pokes through. No dirt, just slime. He can open his mouth but he doesnt look too happy and im afraid he wont eat because of it and I dont want it to get worse. Ive changed the substrate back to coconut bark.
