When I was new I found the search function difficult as I didn't understand some of the terms like, 1.1.1 and I got blasted for asking, really made me 'gun shy' for a while. As far as co-habing I would rather they ask, if they will take advice, then end up with dead or young gravid corns. I totally agree with Joe about snakes being incapable of love or missing each other, but I got blasted for that remark too.
Back to the question no I don't co-habit, won't co-habit. If you want to co-habit go for it but be aware of the risks and don't say they are in love. Snakes in the same hide, probably because that is the most comfortable heat varient. And last but not least just because the pet store does it doesn't make it right.
As for Myst do you have pics of your black and white corn snake? I'ld love to see it.
