I have a ribbon snake who is roughly a year - a year and a half old and I was wondering if I got another female of her species that was her size if they would do well. I know garter snakes are social but I'm unsure about ribbon snakes, Im not gonna get a male because I cant handle breeding. ALSO if I am able to cohabitate should I aim for a 55 gallon or save up for a 75 gallon? I am currently moving her to a temporary 20 gallon enclosure.

Another Question:
I have been feeding her crickets and earth worms primarily and was wondering if I should add small frogs, tadpoles and guppies and what I would need to watch out for. We have an abundant supply of pinkie mice and was curious if I could feed her those or if they should stay chicken food (they are caught in our walls or outside) She wasn't born in captivity, I got her after she got thrown out of our lawn mower but she has healed since and is very sweet.
