I don't currently have a misting system in my tank,... I do have the fogger however... which recently renovated watching how much area these little guys explore and how small they are.. I had to cover my 1/2 inch pvc with panty hose and reapply so they cant climb into it.. my waterfall is a 3/8 hose that travels through the back of the background and punches through the great stuff wall ... the pump is in the back left hand corner that is boxed out so it can fit back behind and be out of site... Ill get a pic of my tank back soon and youll be able to see it more clearly if you would like... thanks for the compliments..
