I keep several snakes to an enclosure. And, yes, yhey do spend most of their time together. I have two in particular who ALWAYS follow each other around, regardless of where everybody else is. And when I take them out for feeding, etc. they always go back to greet each other when I put them back. I can only think they enjoy each other's company. As long as you keep any new snakes quarentined for a sufficient time period before introducing them, and be sure to feed in separate enclosures, They ought to be fine. I don't keep snakes together who's size difference is too great.
