Hello, I really don't get in the terrarium topic alot to read the posts but if I think you tank people are always looking for humidifiers for in there... I found this battery operated one for <20 bucks at walgreens... The box was small so I'm going to assume that the product would fit in the palm of your hand. I found the item here online but there are no dementions. So, if you are in need of something like this- go to your local walgreens and see if they carry it... It's about the same price as one of those foggers cept this won't splash the water all over the place...
