An aquarium having an aquaculture pot and a water fountain is disclosed in which water is recirculated through filtering material in the pot. A tank cover is formed with a central opening in which the pot is supported. A pipe rises from the water through an opening in the bottom of the pot. The fountain is connected to the upper end of the pipe such that water pumped from the tanks through the pipe sprays from the fountain into the filtering material in the pot. The water is purified by the filter material and returns to the tank through drain openings in the pot bottom.
