Hello, recently I have had trouble keeping humidity in my Golden Tree Frog's tank. I recently bought a humidifier (aka fogger) that pumps cool mist into the tank, but as soon as I shut it off all of the humidity floats right out of the tank. I have also tried covering the screen top of the tank and that seems to work well as long as the rags I put over the screen are wet, and I am worried about covering too much of the tank and not having sufficient ventilation. So, I was wondering if anybody knows if a glass top is safe to use for tree frogs or if anyone uses one themselves. I know many people who keep dart frogs use them but I was told that tree frogs need sufficient ventilation.
