Tank size 30+ gal. & wallpaper on 3 sides - check! 
How do you provide water? The green frogs I see out back are knee-deep in water most of the day, this past week or two. Do they need a dish/plastic tub to sit in, or do they need more aquatic a setup for swimming?
& - how humid? I have a live plants & soil setup for my gulf coast toad - I like this a lot. But do greenies need it wetter, like sphagnum moss wet? -& how deep substrate? Do they burrow, & do they need to hibernate? & how often/how much to feed?
I don't HAVE any greenies & prolly won't raise any from tads this year (wood frog tads are enough just now - they're just getting stripes on their hind legs! No fronts yet) but hopefully next year. I really do like the greens, they're pretty & seem not too disturbed by me gawking at em all the time out back.
I really did search the old forums - didn't find much though - just a bunch of green TREE frog stuff, hence the subject title!
Thanks
