ok so heres exactly what you should get a 20 gallon long tank which is suitable for up to a 4 foot snake 2 under tank heaters a ceramic heat emitter and shroud. 2 alife on/ off thermostats. One for hot end and one for cool end. i would set hot to 90 and cool to 80 as long as it is above 75. In order to keep humidity at least 50-60 which is needed you'll prolly need to put a towel over most of the top screen except for where the ceramic heat emmiter is. Also some tanks have a locking mechanism built right in. 2 small black zilla hides which are really cheap one goes on the cool side one on the hot. A water dishg big enough for it to soak in. Personally i use coconut shaving as bedding because it keeps humidity up. I hope this helps =] -Josh
