It is the largest aquarium in the Balkans, and in recent years has become an important attraction for visitors to the city, student excursions, and travelers. Most of the fish in the aquarium are those that have been living for years in the inland waters of Greece, but there are also a large number of foreign species that live in the lakes and rivers of our country.
The aquarium consists of 49 tanks with a capacity of 1 to 1.6 cubic meters, there is a beautiful simulation of Lake Kastoria and a simulation of the river Aliakmonas. Each tank is a separate circuit, with mechanical filters and water oxygenation mechanisms. There are 38 types of freshwater fish, and various other organisms, such as water turtles, crayfish and triton, are housed. In each tank there is an explanatory sign with the characteristics of each organism, its biology and its habits. The bulk of the aquarium's fish was caught with the help of local professionals and amateur fishermen.
