10 Crazy Aquariums

Toilet Tank

Normally the only time fish see a toilet bowl is under very sad circumstances. The Fish N Flush is a playful way to bring aquatic life into your bath with a 2.2-gallon aquarium that is completely separate from, but next to, the toilet's tank. Able to hold both fresh and salt water, the aquarium can accommodate all types of fish, but smaller ones are recommended. The tank is made of impact-resistant acrylic. It runs about $149.
