So I built a terrarium for my sons White's Tree Frog in a 29g high tank, with a false bottom and a waterfall/creek. Planted it with some plants and moss. I guess it's been up several months now and I'm sure there isn't enough air flow in there. Also the stream seems to leak into the surrounding soil, and in spite of the false bottom, the moss is too wet and molding. I shut down the waterfall and drained the bottom of the tank a few weeks ago, just put in a water dish, but it's still too wet. How can I get some air movement going in this tank? I have a screen top. This pic is from the first week it was set up...doesn't look quite as good now lol...
