The aquarium was constructed and opened to the public in the late 1990s as a private initiative.
The interior environment includes a man-made rainforest section with tropical plants and air-mist cooling systems.
The tank contains large South American species such as Arowanas, Pacus, and various species of stingrays.
The water in the aquarium is filtered and heated to maintain the specific temperature requirements of the tropical aquatic life.
Visitors can view the tank from multiple perspectives including the bottom tunnel, the glass deck, and the surrounding walkway.
Obří akvárium in Hradec Králové is the largest freshwater aquarium in the Czech Republic. It features a unique underwater tunnel that allows visitors to walk directly through the center of a massive tank. The primary exhibit holds approximately 130,000 liters of water. The aquarium is designed to simulate a tropical rainforest ecosystem, complete with simulated rain and localized storms. The collection focuses primarily on South American Amazonian fish species. A distinctive glass footbridge provides an overhead view of the tank's inhabitants. The facility operates as a combined educational exhibit and aquatic research center. It is located inside a distinct building complex in the center of Hradec Králové.
