This simple of an answer is utterly false and way over simplified to the philosophies of mixed species. If given ample space, many snake species can THRIVE in mixed species environments. I have seen Red-tailed ratsnakes, a species that seldom reaches the ground, mixed with a Blood Python, a species that never leaves the ground and stays in one place all day, in a mixed species exhibit with no problems. To say that it is risky to mix snakes or to say you don't think my specific mix of three species would work is a valid opinion, but to say snakes can't be mixed at all is a completely false statement.Snakes don’t do well with other species at all
