<p>An aquarium cover (1) comprises the side ventilating hole (2) on which a group of block pieces (3) is formed. An inner side of the block piece (3) is provided with an inner commanding edge (31) higher than an outer commanding edge (33), and the outer commanding edge (33) is placed outside the block piece. The cover (1) has a light chamber (4) set as inlet and outlet ventilation ports, and one side or two sides of which are set with a fan (9). The said aquarium cover has the function of preventing the water entering electric elements from the ventilating hole, which guarantees the electric elements in the cover not influenced by water. The cover also permits to integrally process the heat collected on the upper head face of the light chamber, such that the cover radiates the heat with good effect.</p> |
