    Abstract: An aquarium toy structure includes a back body and a front body with an observation window. A transparent water tank is inserted in the observation window and toy fish having magnets are placed in the water tank. A motor and a rotary shaft having magnets are disposed in the back body. The motor rotates the rotary shaft through belts, so that the toy fish are magnetically attracted and repelled by the magnets of the rotary shaft to freely swing back and forth in the water to mimic the swimming of real fish.
