A water aerating and controlling assembly for an aquarium includes an aerating device for attaching to a container of the aquarium, a gaseous reservoir coupled to the aerating device for supplying a gaseous material to the aerating device, and a controlling device for controlling the gaseous material to be selectively supplied to the aerating device when the gaseous reservoir is opened, such as during the day time, and for allowing an air or oxygen in an environment to flow into the aerating device and to be supplied to the water plants or the water weeds when the gaseous reservoir is closed, such as during the night time.
