Recently I purchased a new 40 gal breeder size tank for my BP Mobius. I was trying to find some more cage furniture to fill up some of the empty space, and decided to get a waterfall with ultrasonic fogger. I was supprised by how it increased the humidity! I barely have to spray mist. I found Mobius chillen at the edge of the waterfall in the fog. Also I was wondering if anybody else is using a fogger. I'll try to get some pics of Mobius in a fog cloud and post them.
