I never thought about it like that, when money comes in I'll make a few modifications until then i'll be very careful about looking for urates to locate areas he may have urinated. Wouldn't the ammonia leave through the top of the tank, much in the same way the hydrated air does? Also, could someone show me a humid hide? I imagine with those in even a glass tank wouldnt really need things like false bottoms or foil on the top to lock in hummidity.
