depends on what kind of temps yo have in your snake room but i would think a small UTH would provide sufficent heat. I would make sure to use a Tstat of some sort tho so it doesnt get too hot...I keep My anateresia in the same racks as my BPs with a gradient from 88-89 at the hot spot down to 82-83 and they do very well with that kind of a setup...only differnce is they need less humidity than BPs
