hello everyone. I am trying to get my hands on 3 pygmy chameleons when I find them. I would also like to put them in a bioactive vic. I have an exo terra that should be good for 3 (2 female, 1 male). Questions: 1. How do you make a bioactive viv? 2. How do you heat them or cool them? 3. Is it true they need uvb?
