Okay, so I don't have a collection- I have one ball that I just moved to a 40 gallon from his 20 gallon setup. But I want to use his old setup to start my collection, UTH's and all. I'll be going to a reptile show in August and want to purchase a smaller snake for the old terrarium. Rats and corns seem appropriate for this enclosure, but when I researched milk snakes it said that they could eventually need up to 60 gallons? I'm guessing they're more active or the information was incorrect. I'm unfamiliar with general disposition of these types of snakes. I love handling my snake almost every day, so that is a factor in choosing as well. If some of these guys hate being touched or picked up, they aren't the snake for me. Suggestions please?
