Greetings!

I have been gaining lots of great knowledge on this website and through this forum. I just got my first ball last night. "Jack Sparrow" (wish I knew if he is indeed a boy) is about 4-5 months old a little over a foot long.
I need to measure exactly and begin keeping track. I got him from a local hobby breeder who has several snakes. He is in good health and very friendly. My set up is a 20 gallon tank with a screen top. I chose reptile bark for the substrate, I think it is Aspen Fir. I made two hides and put one at each end. I have a heater pad underneith the tank and a spot light on top. I picked up a decorative water dish that looks like a rock. He has been raised on mice, pinkies and fuzzies and has been eating once a week. Sunday is feeding time, I am wondering if I should attempt to feed him or should I wait since he is still adjusting to his new home. Since bringing him home last night I have not handled him at all.
I have been wanting a ball python for a while and read lots of books on them prior to actually getting one.
Another question is can I feed him twice a week? Say Sunday and Wednesday to fatten him up and help him grow?
