So I've had three WTF for over a year no and its all been going well.

Id like to improve the tank a little, with a view to get an all natural one when I can afford a new viv.

In the mean time I have seen exo-terra fog generators :- Exo Terra : Fogger / Ultrasonic Fog Generator, are they safe to use in a tank? what happens if the frog gets to it?
