My 'honeymoon suites' are about 70 x 45 cms and about 30 cms high. They're underbed sweater boxes with wheels and a lid and I've drilled lots of holes in the sides. My community viv (and please everyone...this thread is not about my choise to house some of my corns together) is 120 x 60 x 80 cms. I personally have never had problems with housing snakes together but the general consensus is that it may not be a good idea. It's up to you to research into some old threads on this site (do a keyword search) and decide if it's right for you or not. Good luck,
Adèle
