An aquatic ornamental landscape device includes a main portion provided in a water tank and made of a soft material with its specific weight not larger than that of the water so as to float in the water tank, and connected with a down leading member to stay at a certain location without hampering the main portion from swinging or wriggling, a magnetic member provided in the main portion, and a magnetic inducing base provided at the outer side of the water tank and containing a hollow housing to accommodate a motor and a gear set driven by the motor while an axial of the gear set is connected also to a magnetic member which is driven and rotates to generate changed magnetic field against the water tank for the main portion to stay in its place and naturally swing or wriggle when subject to the alternative magnetic force of attraction and repulsion between the magnetic members in the main portion and the magnetic inductive base.
