Predation, Stress, Cross Contamination, and not a good idea. As keepers we are responsible for the care and wellbeing of our animals. To mix any species like this and force them to cohabit is not sound husbandry.
Look at it like this. At zoos ever see herbivores and carnivores housed together. Most zoos have reptiles on displayed. Ever see lizards housed with snakes. Years of zoology education and knowledge keep the animals safe while confined.
My post was not meant to flame you on your idea. I hope this post has answered your question and sparks a good KEEPER.
