I have a couple of snakes who won't ever turn down a meal (even during shed and breeding) that co-hab in a 75, I got them as a pair that the previous owners kept them in for years. I separated them and got nothing except 2 very unhappy snakes, put them back in the 75 together and voila.. I had to very happy, eating and comfortable snakes. Under normal circumstances I agree separation is the best advice, but if it means having snakes refusing every time, trying to take your head off every time you interact with them, it's just not working out. Revert back to co-habing. Oh and all of my snakes are pets first and breeders second.
