Some ingenious plumber cum marine biologist thought up a way to make double use of the flush tank in your standard crapper. This aquarium comes with some fake plants, a filtration system, and a seat with an "Under the Sea" motif. One thing to note before you drop $450 bills on this bit of porcelain: It uses half of its reservoir to hold your goldfish, meaning it probably has reduced ability to flush your home grown sea cucumbers. But note the LEDs - doubly useful for nightime fish gazing and peeing. And when your goldfish turn into floaters, this'll make it easier than ever to give them a burial at sea. – Brian Lam
