Keeping 3 corn snakes housed together?

[Marzipan]

While that petshop is probably doing it all wrong and for the wrong reasons, on multiple occasions I've found more than one corn snake peacefully occupying the same retreat. For the most part, cohabing is a balance of risk and reward that any interested keeper must assess. Just about any snake can either kill or be killed by any other snake if they're thrown together. Most, except bonafide ophiophagous species, don't just slither around killing other serpents.

The thing is, this wasn't actually a pet shop - it was an animal apprenticeship and trainee centre, and these snakes had been kept like that for some time. I imagine that they would continue to be kept like that.

I only worried that the snakes would be stressed out all packed in one hide together, For the record, I didn't actually believe it likely that the snakes would cannibalise each other, rather I mentioned it to them more as a deterrent, since I'd read that it was wrong to keep them all in the same tank without adequate hides.

Thank you though, I appreciate what you're saying. It's very likely that I overreacted.
