The fish tank is in the form of a tank (1), which contains the water (E) and is provided with a system of oxygenation of the exhauster type, which consists of at least one tube (2), which is arranged approximately vertically at one end of the shorter walls (12, 13) of the tank, in the water. The tube has the upper open end (22) above the level of the water. The air supply pipe (7) feeds into this vertical pipe, also above the level of the water. The lower open end of the tube is connected to a length of pipe (3), which extends above the base (14) of the tank, towards the opposite wall (13, 12) of the tank and is pierced with a series of orifices (30) for the admission of water.
