I currently have a corn and a ball python. I don't handle at the same time. When done handeling one I wash my hands and handle the other. I also feed them in their very own seperate cages. I have taken my BP (while handeling) and put him close to the glass of my corn's enclosure. They looked at each other and did not show any signs of aggresions to each other, although I did not hold him there that long. I think that if you are sure that neither one has any diseases then it should be fine to have them both out at the same time. But keep them at a distance from one another. If they did start to go at each other I would put my money on the BP =). But as y'all keep your distance from one another I don't see a problem with it.
