Take a magical journey through rivers, seas and oceans in the Horniman’s highly acclaimed Aquarium.

We encourage you to wear a face covering unless you have a good reason not to.

Our 15 exhibits showcase aquatic environments from around the globe, ranging from the British pond to Fijian coral reefs.

Watch South American fish swimming around in the flooded mangrove roots. 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.

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 behaviours of animals in different habitats.
