hi i own an Australian white lipped tree frog, his been hibernating for about a week now just chilling on his branch, went to change his water and saw the most weirdest thing ever, he was like bloated up, sweaty, and looked like he was peeling or he had like little white string things on him and every time he would like yawn or open his mouth and the white string things would slowly go back in his mouth then he would go real skinny when the white string thing was getting closer to his mouth then soon it all was in his mouth he then was back to his normal self what could this be? was pretty scared when i saw this thank you so much ( and sorry dont have a picture was to slow to get one)
