Hi All, i have a green tree frog and for the past 8 years he has been great. Just today i awoke to a loud bang, and i noticed he was jumping around the cage, falling upside down, had lack of suction on his feet, had heavy breathing, and looked to be digging around the bottom layer of his enclosure. He was showing large levels of activity which has never been seen before at this time of day and im really worried.
He is always fed, enclosure has heating etc. Well looked after, and i dont know if this is signs of the end of his life? He has lots of red-ness underneath his body, and im worried somethings happened to him or im doing something wrong, or somethings going wrong.

Hopefully someone can help, thank you.
