Boooo! Fair enough i know u can keep certain reptiles together and actually lots of zoos make community vivariums. Some of my larger lizards after getting an OK from a vet i put them in a community vivarium and everythings been great. BUT they dont produce toxin. Now i have seen people keep different species of dendrobates or mantellas together so it kinda crossed my mind since they are from the same habitats to do a native species vivarium.
