Hi, well when I first got my Fat Tails I kept them too cold and too humid. Well actually I used an under tank heater, but the air temperture was too cold. So basically I started noticeing sneezing or forceful air expultion. I immeadately got a heat light. I actually made a basking spot slightly hotter then normal (make sure colder areas still exist.) I placed a hide under the basking spot. They spent most of their time in here. Problem went away fairly quickly. I actually don't use under tank heaters since they enjoy the night heat light so much. Only problem is that it triggered breeding for me.

Oh I also dropped the humidity. Personally I rarely spray now.

The warm dryer air really worked wonders.
