I just adopted a male, normal ball python from a breeder last Friday. I named him Dragon. He was born July 2, 2013 (2 months and 19 days old today). He is quite the little character and very spunky. The breeder kept him in a small, shoe box size tub on paper towels. I didn't ask how he heated it or kept his humidity up. I thought I would give Dragon a bigger home and placed him in a 51 quart tub with holes in the side and the lid (the holes aren't small or many, about 10 altogether, each a little smaller than a dime. Inside he has 2 cardboard hides (one on the warm, one on the cool), a water bowl, a 10-20 gallon UTH made by ZooMed, thermometer/humidity gauge in one, and paper towels as substrate. His temperature stays between 75-80. I found out that Dragon likes to climb so I plan on getting things for him to climb on in there (like those thick, wooden logs they sell in pet stores). My issue has been the humidity. I read that optimum is 40%-60%. I can spray it a lot (probably too much, it gets the paper towels wet) then close the lid and get about 60% humidity for the next 20 minutes. After that it quickly goes down to 40% then 30% and about 3 hours later there is no humidity to speak of. Also if I remove the lid anytime I go to take Dragon out, the humidity goes to zilch. I don't like having to spray as much as I do. I don't want to risk him developing scale rot. I have even attempted covering a good portion of the holes with tape, but the humidity didn't improve. I live in Tampa, Florida so it's not like it's extremely cold. We have humidity outside in handfuls >.> Is his tub too large for him? He seems too active and miserable in smaller tubs :/ and there's not much for him to climb on when you're in smaller tubs. I do have a spare 10 gallon tank that I could get a lid for, but I don't have the funds to go out and buy a larger tank than that. I've heard that tanks don't hold humidity nearly as well as tubs tho. So what should I do? Smaller tub? More holes, less holes? Any tips on increasing humidity or improving Dragon's home is greatly appreciated
