I bought some dumpy tree frogs a couple of weeks ago. After reading I realized that the setup the lady had them in (which I also bought) was totally wrong. I bought them a small exo Terra setup, and since two of the babies have died. The adults that were a bright green are dark brown most of the time now. I am worried that I am doing something wrong and more will die if I don't fix what I'm doing wrong. So here are my questions.

Are these even dumpy tree frogs? I think that they are, but I want to be positive as this is the care that I've been giving them.

Is there something wrong with my setup? I've been keeping humidity around 50 to 70 percent and twmp around 75 to 85 Fahrenheit. There is about an inch of clay balls on the bottom that is covered by coconut substrate. There is enough water in the bottom to cover the clay balls but not the substrate. They have a uvb light which I was leaving on for 8 hours a day and a heat pad thing stuck to the back side ( which they never stay on).

I feed them once every two days. I take them out of the tank and put them in a plastic tote and they eat about 2 large crickets each. The one baby I have left will eat 4 or 5 pinheads or knats.

Any help or advice is greatly appreciated!!
