I have heard many people for and others against mixing species. Our local zoo houses all three of these species, along with fire belly newts. I have talked to the zookeeper who has been there 20+ years, and he told me they have housed them together for many many years. He's been in the lizard house at least 15 years, so I pretty sure he knows his stuff. He told me if I was diligent about doing water changes and keeping them well fed there shouldnt be an issue. Also as long as there isn't anyone who is real agressive in there.
We do complete water changes between once a week to week and a half. There is just about 1 1/2 gallons in the tank.


The moss has been removed, replaced with coco fiber. I asked at the zoo, and they have soil with moss living in it. Which may be another option.
Thanks for your help!
