Bunker down for this one pal!!!! you are going to get sooo many different opinions and reasoning. My advice, do what works best for you. I was in the same situation trying to decide. I went with outside the tank just because I wanted to lessen the (risk) of tank aggression. My daughters handle our snake often and I wanted to remove any chance of them getting bit. I feed in a separate tank, let her settle down after eating for at least 25 minutes, then gentle remove her and put her right back into her tank. She has eaten at least 8 times since I have had her and haven't had a problem yet. (knock on wood). Do what works for you!!! Thats my advice
Yup haha It's really cool watching him strike for the first time
