I bought two leopard tortoises today, and the vendor had told me of a vine-like plant that I should buy to keep in the tank, that they like to hide themselves in and is also safe and edible...unforunatly, I thought I could remember the name of the plant, but when I got to Home Depot I had no idea which plant it was...he said its not the vines that grow on the sides of houses, but another kind of vine. If you know what I'm talking about, please help! Also, I bought one of those efficiency lightbulbs to heat their tank. Is that good enough, or is there a specific set up that I should use? Thanks in advance!
