About the water dish.. Water dishes are nice if they use them, but I have NEVER had luck getting any of my herps to drink out of them. Fat tails are not used to the concept of standing water and can not see it. I have never had one use a water dish, so what I do is just mist down the cage daily and they drink the water off the walls, and off of the hides, etc. good luck!
