Is it worth it to butls a rack for two snakes? I don't plan to get any more just yet at least not for another year or so.. has anyone ever built a rack for 2 snakes? What would you recommend besides glass aquaruims( I know they are horrible).. If I Don't Build or buy .. I planned on switching from aquariums to Sterilite tubs, rubbermaid tubs, or iris tubs i need help with this one ..
