Tapir would be a good addition, especially if ZSL managed to get their hands on a Malayan one, but it's unlikely they'd replace the hippos at London if just because of the theming of Into Africa. The Cassons I agree would be the logical place, but I'm not sure that the current RRH exhibit would be particularly good for tapir and I must admit I enjoy seeing RRH and babirusa in the same area. In an ideal world, London gains anteater again and mixes them with tapir. It's unthinkable Whipsnade loses pygmy hippos altogether simply because they are quite proud to hold both hippos species (rightfully so!). Tapon's paddock would be wonderful for tapir, but it is much better for hippos. I would love to see Malayan tapir at Whipsnade though, as surely then they will hold the gold standard for Asian megafauna
