you did something right or the frogs wouldn't be five years old. that being said it is hard to kill a white's treefrog. but seriously you should always research a purchase of any kind, esp. a pet. their life depends on you. glass terrariums are probably better. white's don't need high humidity and the temp is only 80-85 day/70's at night. $50 worth of decorations in the tank and you will have a nice setup. check out blackjungle.com for some ideas at least. they have everything.
