But what I liked was African buffalo, black wildebeest, common ostrich, common warthog, plains zebra, reticulated giraffe, sable antelope, springbok, and Thomson's gazelle all 9 animals enrich one another, red ruffed lemur and ring-tailed lemur both enrich each other, American bison and pronghorn antelope both enrich each other, Baird's tapir, Colombian white-faced Capuchin monkey, and giant anteater all enrich one another, and red kangaroo and koala enrich each other. But sun bear and binturong enrich each other, Malayan tapir and binturong enrich each other, Malayan tapir, proboscis monkey, and Indian elephant enrich one another, and Malayan tapir and Bornean orangutan enrich each other. What about the other animal combinations this time??? This is the first time in planet zoo to see only partial combinations work for interspecies enrichment...
