All I know is he just started eating adult mice about a month ago, so I will ask the other questions. My thoughts on getting this snake instead of from a reputable dealer was the fact that this guy is trying to get rid of this snake so I felt it would be better to get it and give it a good home with instead of going to someone who wont take care of it or end up getting rid of it etc, where as getting it from a reputable breeder who is already taking good care of their snakes. I have a 10 gallon with a crack in the bottom but I assume if I just put enough stuff in the 20l he should be ok because he is currently in a 40 gallon at the guys house. As far as the care sheet goes I have read it as well as one on another site and I look at them constantly. Also, by not handling him for a week wont make him become aggresive at all would it? I am very new to snakes but I currently keep a spoiled bearded dragon who used to be cage aggressive when I first got him because from not being handled a lot where I got him but I can tell when hes upset but I might have trouble reading a snakes mood though, just worried cause I dont want to screw anything up haha.
