In order to help Rich out... I have had the 16 inch Brazilian Rainbow Boa for 4 days. I currently have a 10 gallon tank with screen cover. Mainly got it as a temp enclosure since I bought the animal in California and needed to drive back home to Texas. Looking to upgrade to something much better soon, just dont have room for a vision cage. Cage currently has a medium sized deep water dish. Cage also has live spanish moss covering entire back wall of the 10 gallon tank. There are two hides one on the colder end and one on the warmer end. Cage currently located on counter top in my bathroom since that is the spot where I can keep temps the warmest and feel like I have the best chance of maintaining more consistent humidity without making the rest of the house unbearable. Im using shredded Cypress Bark about 2 inches deep. For lighting I got one red light and one day light witch has only one going at a time. Temps are mid 70's on cool end high 80-low 90's on hot end. Humidity is fluctuating from 60-90 in between mistings with a spray bottle. Havent fed yet but planning to Sunday. Animal was last feed a week ago today. Just got back in town last night and wanna let the little guy get over the stress of being transported and settle down a bit before feeding it. Looking to get a better control on the humidity. I would like to keep it a lot more consistent than I can right now by using a spray bottle. I was looking at getting one of the misting devices from Petco. Do they work? Are they worth it? How adaptable are they to being used on various types of cages? Dont mind spending a couple of hundred to solve this problem if its something that will be effective. I would like something thats adapatable from one cage to the next as well to the extent possible as my critter grows and needs a larger enclosure. This is something that I have constantly struggled with to one degree or another for the most part living here in North Texas. It was much less of a problem when I had a breeding pair that were in a walk in vivarium as opposed to using screen top aquariums. I would really like to hear what the more experienced here think about this issue and ways to better address it. Not above spending some fun dollars on an Exo-Terra enclosure too if this would be a better set up and help control the humidity levels as compared to a screen top aquarium.
