The only "issue" is I don't see them now, so many places for them to tuck into and get outta sight. I guess that makes for happy frogs but not-so-happy frog watcher. Tell tale signs that they've been out at night is the poop in the water dish, and small pieces of sphagnum moss dragged outta the hides. I'm trying to find some shag moss to tuck into the hides, seems everyone is either out, or shipping is outrageous.
