ABSTRACT:
An outdoor fish aquarium has an upper and lower part, where the lower part is a cylindrical well where the fish would be safe from freezing weather. The aquarium is designed so that the water in the well would not all freeze in the coldest parts of the year, so that the fish could survive in the well when the rest of the water in the upper part is frozen.
