well the two corn snakes I have were brought in together and the lady who sold them to me said it shouldn't be a problem housing them together as long as they have enough space. I bought a nice massive aquarium and put lots of spots for them both to hide. However, it seems they are conjoined at the hip because they always pick the same hides! if one moves, the other will follow, regardless of which one moves first. Is this behaviour anything to be concerned about?
