I have a white's tree frog that I was given to me not too long ago. The lady had him in a clear rubber maid tub w/ lid the whole time she had him. I have an empty tank that i want to put him it that measures roughly 20"x18"x36", it's a very tall tank. I have fake plants, lights, bed-a-beast shredded wood substrate. The top is a sheet of glass that has a gap on each end to allow ventilation, about 1" on the left and 1" on the right, over the top of that i have a screen cover the covers the whole top to prevent the frog from squeezing through the cracks. Seems like a pretty good setup, BUT I can't keep the humidity up, I can spray it down really good, but i gets dry pretty quick. Anyone have any suggestions on ways to make the moisture stay in?
