My tincs are often found on top of pothos/alocasia an inch or two from the lid of my 29 gallon tank. I find my auratus on top of pothos (and evicdence they've been there, anyone else notice their frogs seem to poop high up in plants? my aurotania which I've *never* seen climb I've found poop atop the tallest plant in its vivarium). Oddly my leucs climb up in plants to sleep, but that is the *only* time I see them up there, the rest of the day they hide in their little cave or search the bottom of the tank for flies.
