I have started taking care of a frog as a pet. He is a rather basic frog, an American Green Tree Frog, whose name is Glenn. My terrarium is 24/18/24, and I have on the ground, a fountain w/ a filter, in water that fills halfway ( horizontally ) , with stacked flagstone on the other side. I have a plant for some foliage, some logs and sticks so he can climb, and one of those vines that you can twist. I just got him today, and I've had a few problems, and concerns. When I feed him the crickets, some of the crickets go in the water, so the water doesn't seem like it's helping but I really like the water. My concern is that he is always walking on the glass on the right hand side, he never want's to go on the tree sticks or the flagstone.

I just wanted to get criticized on how I'm doing so far, and what I should be doing to take care of him. Should I mist him? Or have any lights?
