Abstract: A virtual fish tank assembly for displaying three dimensional aquatic creatures includes a housing structure. The housing structure is positioned adjacent to a fish tank. A projector is coupled to an interior space of housing structure. A control module is in electric communication with the projector. The control module obtains data from a user, reads the data, and generates a plurality of three dimensional images. A power source is in electric communication with the projector and with the control module. The power source provides power to the projector and to the control module. A screen has a peripheral surface and a back surface. The peripheral surface attaches to a respective one wall of the plurality of walls of the fish tank. The screen displays the three dimensional figures projected from the projector to give the appearance of the figures being within the fish tank.
