Hello this is my first time keeping anything besides fish so I'm a little new/worried, I got a pacman frog about a week and a half ago and he's been fine so far but after I turned out the light I look in his enclosure and see what looks like his tongue sticking out with some moss on it. So i rinsed my hands in lukewarm dechlorinated water and went to get the moss off when i realized it wasn't stuck on it, it was inside of it, I am pretty sure it is his stomach sticking out! The moss wont come out either and I don't want to pull hard enough where I hurt him. What should I do?? How long can he survive like this?? Any and all answers are appreciated.
