@MOG2012, based on both casual observation and quick research; this is how I would divide the following:
Grey Mouse Lemur x Tenrec
Aye-Aye x Flying Fox -
(an irl version with Straw-Colored Fruit Bats exist/existed in Omaha)
Sunbittern x Boat-Billed Heron x Turtles x South American Fish
Night Monkeys, Tamandua, and Bats are all maintained in separate, single-species areas
Beaver x North American Fish
Opossums and Night Herons are maintained separately
Aardvark x Straw-Colored Fruit Bat x Bushbaby -
(similar to Cincinnati; albeit, with smaller bats and primates)
Cape Porcupine x Bat-Eared Fox -
(an irl version exists at ZooWorld Panama City Beach in Florida)
Finally, both Hyraxes and Dikkops are mixed with different species in separate enclosures.
