ABSTRACT:
A marine display is provided having a housing and a transparent vessel at least partially filled with liquid. A magnetic animated marine life such as a toy fish is freely suspended in the liquid and at least one rotating magnet in the housing generate magnetic fields which co-act with the magnetic toy fish to cause the fish to move in all directions to simulate the swimming action of a natural fish in a liquid habitat. A background plate in the housing behind the liquid vessel imparts aesthetic marine-like appearance to the display.
