I am toying with the idea of adding 2-3 female leos to my collection. They were the first herp that got me into the hobby (I didn't keep any, but thought they were gorgeous and did research, etc.) and now that we'll be buying a house and I'll have more room for herps, they are on my list. That said, after getting used to how low-maintenance snakes are and having kept my crested geckos for a while, I want to make sure that they will work in my collection (maintenance-wise).

With that in mind, I have 4 questions for you guys that will help me decide if they would be a good addition for me.

1. Can leos be housed in a rack system with just UTH (if not, what do you prefer to house them)?
2. What would an average feeding schedule be for an adult leo (number of bugs and how often?)
3. Could leos be kept healthy on a diet of only meal/super worms or with the addition of dubia (no crickets)?
4. How plausible is it that female leos (if the same size) could live together without issues (or would it be better to do smaller individual tubs)?

Thanks for your time and help!
