In order to generate waves in a volume of water ( 12 ) of an aquarium, it is proposed that a storage container ( 22 ) which extends beyond the surface of the volume of water ( 12 ) should be provided in the aquarium ( 10 ). Using a pump ( 32 ), water is periodically pumped from the water container ( 10 ) into the storage container ( 22 ) and returned from the storage container ( 23 ) into the aquarium ( 10 ). The energy delivered to the water during this leads to fluctuations in the position of the free surface ( 14 ) of the volume of water ( 12 ) and in-phase operation of the pump ( 32 ) provides stronger surface displacements in the aquarium ( 10 ), which are comparable with a wave in open water and which expose the plants and living beings in the aquarium to an alternating mechanical load.
