So I made a small change to the tank, I put the fern down in the water so it creates like a mat for crickets, and there are lots of things for the frog to climb out on if it falls in. I also added another potted plant, it is a much bigger pot and holds a snake plant. The pots all have solid bottoms with no holes.

Since I've put him in here he has been much more active, and has even started vocalizing, so I assume that means I have a male? I can't wait to add a few more frogs!
