ZSL Whipsnade Zoo opens the UK’s first Aquarium dedicated to conserving the world’s most astonishing and endangered freshwater fish. Opening Friday 26 July 2019. Fish that can jump out of the water to pluck fruit from trees, have evolved to no longer need eyes, or even live out of water for more than two months, are among the incredible species that will call ZSL Whipsnade Zoo’s new Aquarium home.
