ARIUM
[about ARIUM Festival]
Welcome to the official website of the 3rd Hellenic Exhibition, ARIUM

ARIUM (Palludarium, Vivarium, Aquarium, Terrarium, Formicarium, etc.).

The 3rd ARIUM transforms Athens into a global attraction for the nature-loving community, offering a rare escape into the exciting world of exotic species. This year’s event goes beyond the narrow confines of a traditional exhibition, offering an experiential tour that stretches from the tropical forests of Southeast Asia to the aquatic habitats of the Amazon.

At the height of interest, the 5th International Competition “Best of Discus 2026” highlights the pinnacle of aquarium art, bringing to the fore top examples of the “King of Aquariums.”
The competition process is framed by high-fidelity model constructions, which function as living tables of geographical accuracy. Each exhibit is designed to strictly mimic the conditions of the natural environment, combining aesthetic harmony with the latest developments in wildlife conservation technology.

The educational dimension of the festival is enhanced by an international team of renowned speakers who share their expertise with the Greek public through in-depth seminars and presentations. Interactive tours and live demonstrations offer a level of immediacy that is rarely found, allowing hobby enthusiasts to delve deeper into the scientific training and ethics required by the modern philosophy of ARIUM. In this way, the 3rd ARIUM is not just an event, but a benchmark that redefines the way we perceive and protect the biodiversity of our planet
