The present invention pertains to an air supply device for an aquarium, and more specifically, to an air supply device capable of forming fine air bubbles when external air is supplied and mixed with the water in an aquarium such that the air dissolves faster into the water so as to increase the amount of dissolved oxygen. In order to achieve this objective, the present invention comprises: an air supply pipe for supplying external air; a water suction pipe for sucking the water in an aquarium; a mixing connection pipe connected to the air supply pipe and the water suction pipe; a connection member provided between the mixing connection pipe and the water suction pipe; and a mixed water discharge pipe connected to the upper portion of the mixing connection pipe, wherein a sealing section is formed on the inner peripheral surface of the mixing connection pipe, and a fine inlet path is formed in the inner peripheral surface of the sealing section. |
