Mammals, birds and fish have been housed together for a long time. I have seen relatively few mixed exhibits with reptiles. What mixed exhibits have you seen, and do you know the degree of success? It is to be noted that I have seen a lot of mixed exhibits containing turtles, so maybe only suggesting the most interesting of those would be great. I also wonder if there have been any attemps of housing snakes with other animals? During my recent visit to Tierpark Hamburg they had an exhibit with gila monsters, chuckwallas and toads. However, I am unsure if the gila monsters actually were together with the rest because they were in a cave when I saw them, and didn’t see an opening.
