When it comes to snake they can get through any hole that their head will fit through, even an adult corn is an escape artist. You're luck to have found him!
Longer tails do mean males, but if you don't have two different sex snakes to compare it's hard to tell what is 'long', so you need to count the tail scales, if you google 'visual sexing cornsnakes' you'll find some tutorials.
Ash is a great name (Ashley is one of those girl/boy names) and of course I'm a huge Evil Dead fan so it works for me.![]()
