Hello and thank you, that you took the time to explain all this.
And I want to say some words about your concerns.
Cannibalism: This isn't very likely. They lived together all their lives and never did anything to harm each other. Why should that change now? (it's nearly four days now and both are still well by the way)
Checking poo and health: Ok, that's a point I accept completely. But since they will get the same food and water and are taken care of by the same person (me
) and even if I would have two tanks, they would stand near to each other (so airborne infection or exogenous parasites could spread anyway), there would be a pretty good chance, they both would become ill, if one of them was.
Your major Point: snakes are solitary: That's true, in the nature, there are no such things like corn snake herds. And your opinion that they don't like other snakes is understandable. But even if they live alone in the nature, because there are no benefits for them in gregariousness, that doesn't mean they suffer from one another.
I read a scientific article titled "Intraguild predation, thermoregulation, and
microhabitat selection by snakes". They tested, which sun bathing place corn snakes choose, given there are 1) no other snakes around, 2) the smell of a king snake was detectable or 3) the king snake itself was around. They tested snakes of several ages. (I do not support animal experiments by the way, but the article exists so why not broaden one's knowledge.)
As the observation showed, if the corns had to choose between a colder spot alone and a warmer spot with a king snake on it, they often chose the warm place and risked predation.
I know this is a little bit off topic and not exactly what we are discussing about, but if snakes prefer warmth in company of a potential predator over a safe cold spot, then why would they bother about another (harmless) companion in the tank?
Besides they have two sun spots and several hiding places in my terrarium so they can avoid each other if they want.
By the way, I had to work and/or live with people I don't like several times and you can bet that this interfered with both my behavior and my health. So if you "locked me in a small house with another person I don't like AT ALL", you would be able to tell by watching. Of course this wouldn't be healthy, you're right, but you could see it for sure.
And therefore
my personal opinion is, that you are able to notice if another snake in the tank affects the inner balance of the animal.
I know this wont change your (and everyone else's) opinion of me and of the whole cohabing-subject. But all this is reason enough for me to try it, since it worked for so long. Above all: If I hadn't got the two guys, they would still be in their old home, together as well, but in a tank half the size of mine.
Thanks for your time.
Best regards,
