reliable rough green snake care info?

so, i really like these snakes and plan on getting at least one some day, but my last post to satanas thread made me realize that every caresheet ive read on them has been different in one way or another, so i was wondering if someone who owns or has owned them can tell me how to actually care for them. mainly i just need temp, humidity, and more feeding info, and also need to know if they can be housed together. i'd be willing to make sure i get the right sex to house them together if it matters, either way im gonna try to get all of one sex if they can be housed together. and also, is there a difference in how i would care for a florida (carinatus) vs. a northern (aestivus)? thanks in advance
