Ok so I just finished building a 60 gallon tall snake cage. I now want to start landscaping it with real plants and a lagoon w a waterfall. I also plan on installing a underground den that I can access to clean and what not. I'm going to be using expand a foam and styrofoam, unwanted grout,clay flower pots and a Tupperware container for the waterfall. My questions are whatare there type of plants will not be compatable with my ball python? are there any plant that are poisonous to them etc.
