I'm looking into building a snake rack because I am enjoying my ball pythons a lot to where i would love to have more, but I can't stand having aquariums all over my room because they are space consuming. I have researched many different size tubs that are recommended by breeders, but they just seem too small and cramped to me. What are good size tubs for baby, yearling, and adult ball pythons that will not be humongous but my pets will be perfectly comfortable living in it?
