Has anyone ever used one of the ultrasonic cool water foggers in a tank with frogs? i have mine piped in now, but i am looking to build a mini tank for a new batch of frogs. I hear that some people say that it wont hurt them and others that say that it will kill them in an instant. Looking for anyone that has actually used one of these in conjunction with dart frogs and what kind of precautions (if any) do you need to take.
