Re: mixing/multispecies exhibits.
I think Ed brings up a really important point, the floor space is often the only part of the tank being used, at my local zoo there are enclosures that are 5 feet high, 3 feet long and 2 feet and the tanks are housing pac man frogs. I know we are talking about mixing species, but the space given to single species tanks is also important. The floor is covered half by fake tree roots leaving the pac mans about the floor space of a 7 gallon. What is the purpose of these exibits; to educate? if I knew nothing about frogs and saw this exibit I would see nothing wrong with it, not knowing pac mans do not climb and I would walk away thinking that they do based on what I had seen. But what are zoos teaching if they do things like this?
Also, there is also a tank in this exibit that houses D. tinctorius, D. azeurus and D. auratus. As part of my job as a volunteer at the zoo is to tell people about these frogs and I cannot count the times people have asked where to them and proceeded to tell me they were going to get a "blue one, a green one, and a yellow one." Of course then I tell them mixing is not such a good idea for most situatuions. But it's hard to provide an argument against mixing species when you are standing right in front of a tank at a zoo housing three different species. I think that if zoos are going to do this they should provide information about doing this at a private level.
About the reasons for mixing species; animals look exactly the same whether they are housed with other frogs or individually (per species), so what is the appeal of mixed specie tanks? Why not have separate tanks for each species? They will be smaller but still have the same amount of room per frog.
I am not saying mixed specie tanks cannot be done, I have seen many sucessful tanks at zoos, but for the average person it usually doesn't come out right. They can be done with a lot of research, funds, and space but a lot of people dont have all that stuff.
FwoGiZ- in response to your question, I suggest you read all the pages in this post as they will probably answer a lot of your questions, and keep in mind that Ed works at a Zoo and is pretty good at what he does. and I also suggest you rethink your mentality on "stupid gallons and stuffs" as you will find out that stuff matters, just a little.
