ABSTRACT:
A mobile aquarium includes a display tank mounted on a wheeled cart and a system for lowering the center of gravity of the aquarium. In one embodiment, the system for lowering the center of gravity uses a storage tank that is lower than the display tank. The system transfers water from the display tank to the storage tank for moving. The lower water level in the display tank is kept high enough to provide a livable habitat for fish in the display tank. A background lighting system for the aquarium includes a light source and a semi-opaque sheet with a first image on a first side and a second image on a second side. The light source illuminates the sheet so that the second image shows through the first side of the sheet and appears behind the first image. In one embodiment, the first image has a graduate color that is lighter at one end than the other.
