I'm not 100% sure on how long they live either...I seen some websites say 15 (well...from what I saw on the websites I visited anyways.)...My first whites tree frog Chaos (he was a escape-artist btw) lived with me for about six or seven years (might be wrong on the amount of years...it was somewhere around there.) though...I'm not really sure how old he was as the only indication to his age that the store gave to me was that he was already a adult frog. (I miss him...he loved sleeping on my shoulder. ^^u)
