Armadillos really aren't good display animals in any exhibit.

or possibly peccary and coati?
Works at the zoos of Plzen and Schwerin, among others.
The one that I think jbnbsn99 is thinking about is the one at Artis, Amsterdam, Netherlands (unless there is another one in Germany as well?) which mixes African Penguins with Californian Sea Lions..
I saw marine turtles mixed with small-clawed otters at the aquarium on Sentosa Island back in 2006 (or 2004? I can't remember which year). Seemed like a thoroughly stupid idea to me (and the enclosure itself was pretty small as well).Sea turtles are mixed with fish in many aquariums around the world, ranging from small reef fish to large sharks and rays. There are some variations depending on the exact species (e.g., hawksbill may take smaller fish if it can catch them, green doesn't) and keeping them with large bull or tiger sharks would be a very bad idea. I don't remember any exhibits where aquatic mammals have been mixed with sea turtles, but presume dugong would be unproblematic, whereas dolphins and pinnipeds would cause problems (at least stress and sea turtles don't handle that well).
