The present invention relates to an aquarium having a filtering function so as to facilitate the growth of aquatic organisms such as fish, crustaceans, shellfishes, and aquatic plants. According to the present invention the aquarium having a filtering function is configured to include: a porous horizontal partition wall which horizontally partitions the inner space of the aquarium into an upper growing region and a lower filtering region and a filtering device which is disposed at a predetermined portion of the horizontal partition wall and provided with a filter so as to suction and filter water in the growing region and discharge the water to the filtering region. The water, whose pollutants are filtered using the filtering device, is allowed to move through the pores of the horizontal partition wall from the lower portion to the upper portion of a floor material, such as sand or a functional material, which is stacked on the upper surface of the horizontal partition wall. As a result, pollutants concentrated between the grains of the floor material are floated using the water in the growing region, and the water containing the floated pollutants is absorbed back by the filtering device in order to be filtered.La présente invention concerne un aquarium doté dune fonction de filtration de façon à faciliter la croissance dorganismes aquatiques comme les poissons, les crustacés, les mollusques et les plantes aquatiques. Selon la présente invention, laquarium ayant une fonction de filtration est conçu pour inclure : une paroi de séparation horizontale poreuse qui sépare horizontalement lespace interne de laquarium en une région de croissance supérieure et une région de filtration inférieure et un dispositif de filtration qui est placé au niveau dune portion prédéterminée de la paroi de séparation horizontale et est muni dun filtre de façon à aspirer et à filtrer leau dans la région de croissance et dévacuer leau vers la région de filtration.
