Beside the great Iguaçu Falls, a new aquarium is teaching visitors to love the rivers too

Most visitors to Foz do Iguaçu, Brazil come for the falls — and leave without ever meeting the rivers that feed them. AquaFoz, a new aquarium near the entrance to Iguaçu National Park, is built to fix that: 23,000 square metres and 3.3 million litres of water holding about 300 species, from the Iguaçu surubim catfish and golden dorado of the local rivers to Amazonian and ocean life. Beyond the tanks, its team supports research on the Floriano River basin, on microplastics in rivers, and on conserving the surubim itself — turning a day out into a reason to protect the water.
