Question about breeding

Well here it goes. I was wondering how big a tank needs to be to hold 2 ball pythons male and female. Or is it an absolute must to have two seperate tanks and bring them together every year or so to breed?
Thanks,
Marcus

They should live in their own enclosures and only be put together to breed at the proper times.
