Is there a reason my WTF "burrows" into the moss I'm using as his substrate? He was climbing around last night on some vines and relaxing in his water bowl, but the past couple of days he's just really "digging" the moss. It's cute... when the lights come on, he'll just bury himself in a ton of the stuff. I keep the humidity as high as I can with frequent misting several times a day so it's between 60-85% in there.

This moss is also brand new to him, you think maybe he's just enjoying it? I used coco fiber until he got wickedly sick with staff infection on top of some other disease nobody could figure out and then all he had was paper towel with no decor. Now he's fine, I just didn't know if it was okay for tree frogs to enjoy this moss so much :P
