Explore our Aquarium

Our fifteen exhibits showcase aquatic environments from around the globe, ranging from the British coastline to Fijian coral reefs.

Watch tropical butterflies fly around a living rainforest display with South American fish swimming around in the flooded waters below. Nearby see the poison dart frogs and tropical tree frogs.

Get close to a live coral display and see reef fish move between and interact with this complex and vibrant habitat. Observe the symbiotic relationship between a clown fish and its host anemone.

Wonder at the bizarre structure and movement of pelagic jellyfish, moving around their purpose built aquarium

During your visit, you'll not only get to see amazing animals up close but also learn about their interesting lives and the places where they live in the wild.

A huge variety of aquatic life can be seen, displaying the massive variation in the body shapes, colours and behaviors of animals in different habitats.

We are working to reopen the displays as soon as possible and apologise for any inconvenience.
