The short answer is NO is is a bad idea to house two snakes together. There are some whom have the expertise to pull it off but even then it means in many cases any treatment needs to be done to both. (fecal samples two together if one sample comes up with parasites both have to be treated. You cannot feed together and some snakes stress if moved to a new enclosure before feeding. It is a poor idea with out a massive amount of skill and knowledge.
