Whites tree frogs are very forgiving when it comes in keeping these frogs. The color of the frogs is also a good indicator of the temp/humidity is in small contrast,not extreme drops. The extreme changes could be bad for them. If the frog is bright green,its cooler and dry. If the frog is brown, its warmer and humid. I tried an experiment and it worked. I had the frog in a warm and wet tank,and the frog was brown/purple/ green. When i took him out side,in the fresh cool air, he turned all bright green.
