ABSTRACT:
A novel aquarium assembly includes a transparent fish tank that is made of integrally molded plastic. The fish tank confines large and small receiving spaces therein. A top cover is mounted removably on the open top of the fish tank and is formed with an opening to access the large receiving space. A U-shaped filter strip is disposed inside the small receiving space and divides the small receiving space into a first compartment and two second compartments on two sides of the first compartment. The second compartments are communicated directly with the large receiving space. An aeration unit includes a vertical water tube, which is disposed in the first compartment and which has a lower open end that is communicated with the first compartment and a top open end that extends toward a top of the large receiving space and that is formed with a radial hole, and an air tube which has a first end that is connected to an aeration pump and a second end that extends into the water tube via the radial hole and that is connected to a porous plug.
