Many people here at ZooChat seem pleasantly surprised by the cheetah/white rhino mix at Borås Zoo in Sweden and for all I know it might be the only one in the world?
I think in general mixed exhibits are good. It shows how animals interact in their natural environment.
But some other mixings are highly unnatural- e.g. the Spectacled Bears/Tapirs/otters etc or the Pygmy Hippos/Mandrills, both at South Lakes in the UK to give two of the more extreme examples. Just because they come(not the Otters) from the same country or habitat is not a good reason to force them to live in close proximity in captivity, and I am sure it is stressful for at least some of the species concerned.
Not the first time thats happened I`ve seen it happen myself at South lakes but it was all over before I could get my camera out of the bag,except when I saw it happened away from the pool.Also I doubt it will be last time that it happens.Check out these photo from South Lakes of a dispute between a bear and a tapir. I hope the tapir was ok! Poor thing.

Many people think this, but in fact, while several species in the wild may live in the same area, and share the same environment, they nearly always avoid any direct form of interaction and keep large distances from each other.
Mixed exhibits in Zoos promote this fallacy but the animals don't have any choice as they are forced to live in much closer proximity with the other species that share their enclosures. With Ungulates I think mixed species exhibits can and do often work okay-though there can be specific problems even here e.g. zebra/antelope calves, mothers with young, males of different species fighting etc.

I don't think Disney's predators all live in the same enclosure.I don't know if this counts because they all live on the same continent but Disney's Animal Kingdom has many different African predators all mixed together in one exhibit on their safari ride (Nile Crocs, Cheetahs, Lions, ect.)
I believe at one time the Beardsley Zoo had Warthogs and Galapagos Giant Tortoises together (years ago. Neither species is at the zoo anymore but they're looking for a giant tortoise. The exhibit they were in is now home to the Northeastern U.S.'s first Chacoan Peccaries and its first Chacoan Peccary piglet).
