Any weird mixed exhibits?

[DaLilFishie]

Not geographically inaccurate, but the most bizarre mixed species exhibit I've seen was at Osaka Aquarium - no less than three Giant Pacific Octopuses Enteroctopus dofleini and a shoal of Bigfin Reef Squid Sepioteuthis lessoniana kept in the same tank. I can't think of anywhere else that cohabitates cephalopod species like that.

When I visited the Philadelphia Zoo’s Rare Animal Conservation Center not too long ago. I came across a rather peculiar mix between two White-Faced Saki males and a pair of Black-and-Rufous Sengis… Even weirder, the sakis were not the only animals mixed with sengis in the same building; for I also saw the latter species alongside Pied Tamarins, Bolivian Grey Titis, and a Two-Toed Sloth, to name a few examples.
