I would recommend keeping them in pairs. Mice and rats really need partners for their physical and mental (social) well being.
I did buy a pair. I typed that out without really thinking - I bought a pair of females because I read that they don't like to be by themselves.
And thanks for the input. I hope that as long as I don't let them snuggle with Stan they will be just fine!
