A 30-Metre Aquarium for Blacktip Reef Sharks

Within Fjärilshuset, the tropical rainforest maintains a temperature that never goes below 25 degrees during the day, and is at least 25 degrees even at night. This stability is intentional, providing the necessary environment for 1,000 tropical butterflies to fly freely across 5,000 square metres of space.

Since 1989, this facility has integrated a humid forest with a complex water system. This infrastructure supports a large number of different fish species and allows several thousand butterflies to live here over the course of a year.

Your exploration continues at Haga Ocean, a 30 metre long aquarium holding 1.2 million litres of water. As one of Scandinavia's largest shark aquariums, it offers a close look at blacktip reef sharks and rays, while featuring permanent exhibitions on coral reefs and various marine environments.

While the museum welcomes 350,000 visitors each year, the mission of discovery extends outside the walls. Since 2019, the facility has maintained butterfly beds on its grounds to support pollinators in the nearby urban area.
