The present utility model discloses a device for creating decorative waterfall for aquariums. The device includes a vertical glass plate, a sloped platform containing particulates arranged at the bottom front portion of said vertical glass plate, a vertical pipe secured at the front of said glass plate, an air tube adapted to be supplied by an air pump inserted through the vertical pipe, the bottom end thereof situated slightly higher than the bottom end of said vertical pipe such that the air released at the bottom end of said air tube will go up through said vertical pipe. The air going up through the vertical pipe creates a pulling force which pulls up the particulates through the vertical pipe, released at the top end thereof, and go down back into said platform resembling a waterfall.
