Another fine example of Chinese ingenuity, this toilet combines fish keeping practicality with water saving economy. Not only does it incorporate water saving technology, with a direct connection of the flush function to the water supply obviating entirely the need for an apparently wasteful reservoir, it is also a shrewd piece of marketing, as with no need for a water reservoir the aquarium serves no purpose other than to draw onlookers and prompt questions about what happens to the fish, easily fielded with a informative lecture on the new water saving technology.
