BAD idea, as is the housing of your two ball pythons together. Trust me, they do NOT love each other. When they are intertwined, they are competing for the best spot in the enclosure.
The best analogy I've seen was what Adam said one time. Two kids are playing, one decides they want a cookie. The other wasn't even thinking about a cookie, and there's just one cookie. Now they both want the cookie. They fight over it. One wins, and one loses.
Same thing with your snakes, one decides to go to another part of the enclosure, the other follows, because hey, it must be better over here if my cage mate is going there. One is winning, one is losing.
Besides the fact that if one gets sick, they both get sick, you won't be able to tell who's feces is who's, and a whole host of problems.
Time to separate them. One snake (regardless of species) per enclosure!
