Fish 'n Flush is a patented, two-piece aquarium toilet tank, designed by AquaOne Technologies, Inc., an innovator of water-management systems. The aquarium has a 2.2-gallon capacity. When you flush, it looks like all the water is draining out of the tank and the fish are going down, but it's an optical illusion: the fish are actually safe in an outer aquarium made of high-polished plastic. What you see draining is the toilet water in a separate tank behind the aquarium.
