yes make sure if you don't have an under the tank heater....(I thought I read that you do) you keep a red heat lamp on him. The temps should be 82-83 cool....92-93 hot.

As far as the prey....make sure you go with something that is the size of your snakes thickest body area. A hopper might be too small....that is something you typically feed hatchlings. I am not sure if you know what your snake weighs or not?? That might help with an idea about her size. But picking out the size of a feeder is a hard thing when you are new. I always questioned myself with this. Still today it never ceases to amaze me how big they get their jaws.
