A toy fish drive causes one or more toy fish to swim in a natural fashion in a transparent aquarium (viewing tank). A magnetic drive is connected to the external side of the wall or bottom portion of the aquarium and is supported from the side. The drive has two opposite sets of magnets which are rotated to exert magnetic drive forces on a swimming toy fish in the tank, the toy fish containing a magnet and swimming at a selected sinking rate. By means of the attracting force of the magnet in the toy fish, and the action of the magnetic drive forces of the rotating magnets, multiple toy fish are made to swim separately and in different directions simultaneously.
