my brother has 4 pythons, 2 ball pythons and 2 Borneo short tailed pythons, I've handled them before, pretty cool snakes. i asked him if i get a snake, what should i get, and he told me a king or corn snake. i went with corn since he told me they were a bit less "bitey".
and as for the expo thing, i want to just get 1 for now, not gonna breed yet since i don't have much experience, but i want to start out with a normal.
