Your first three will never be seen at Chester. the zoo's collection plan excludes species from Australia and North America, only because the zoo has no conservation projects in those countries. And they do not intend tostart any, the Americans and Australians are doing a great job on their own. Loris and hippos could appear in the future.
I'd like to see an herd of common hippo, West Midlands Safari Park have a group and it looks great.
Malayan tapir is one of my favourite species as well, much nicer than the American tapirs
