>>I have been out of the hobby for several years so I need some help. My daughter wants a snake so I'm going to pick up a 06 normal female ball. It's been so long since I kept a single snake in a display tank that I have no idea where to start. What would you guys recommend for a basic ball setup? Clay
What has worked best for me as a display tank for a young (less than a year) ball python is a 20 gallon, long tank. For bedding I use ecoearth (some kind of coconut fiber mix) mixed with repti-bark. I use that particular bedding because where I live it's rather dry, and that keeps the humidity up where the balls like it. A water dish big enough for the snake to soak in is also in there, and I like to keep mine right inbetween the warm and cool sides of the tank (more on that in a sec). Also in there is a hidey, which could be a half log, fake rock cave, or a shoebox. With my baby there's a branch for climbing and she does like to use it, but it's harder finding a branch that'll hold up to my larger adults.
Heating is important. You want your hot end to be 90-95 degrees, and your cool end to be 78-82 degrees. In a 20L I have success with using an undertank heater which is always on and the right size for a 20 gallon tank, along with a heat lamp. For my 20L I have a 60 watt red bulb on there, and when the house is in the 70's or lower it creates the heat gradient I mentioned. When it's warmer than the mid 70's you HAVE to monitor the temperatures in there - it can get really hot really fast.
For an adult snake, a 55 gallon or a 40 breeder works well and looks nice - the snake can stretch out and watching them in the evenings is pretty neat. However, a bare minimum is having a smaller adult male in a 20L and a female in a 30 gallon. Not really recommended, but if you're in a pinch it can be done.
I hope that helped!
