Rosy boa, rough scaled sand boas, childrens python?? which on?

The best of these is definately the childrens python. they are similar to the ball except for humidity wise. keep them about 40-55 percent humidity in the cage. they need a basking temp of around 88 degrees farenheit and a cool end of around 72 degrees. a 40 gallon breeder sized cage is plenty for an adult female at 5 feet and 2-3 inches around. hope this helped!
