The Moody Aquarium Sink is a unique way to change a boring bathroom fixture into something spectacular. Sold through Opulent Items, this "living aquarium" sink has a top that can be removed for cleaning and rearranging, a filtration system, and two openings on the sides for feeding the fish. A light is found in the back part of the fixture which creates a calming glow. The unit can also be transformed into a Zen rock garden or whatever type of display case you prefer. The aquarium currently sells for a whopping $4,500 but this distinct sink acts more like art; it's sure to evoke a visceral reaction out of your guests!
