Abstract
Abstract An aquarium assembly comprising a transparent tank body wherein its base, side trim, and lamp hood are each of a synthetic resin material in order to increase the life of the aquarium and to prevent any contamination of the water from metallic rusting. A perforated filter plate spaced from the base, or a plurality of interconnected perforated filter tubes are disposed within the tank, and a biological filter for controlling the waste buildup in the tank is supported on the filter plate or tubes. The tank may be multi-compartmented defined by means of divider walls and a central upright tube through which the air tubes extend for each compartment, and through which the electrical wiring for the lamp may also extend.
