The Hypnotic Jellyfish Aquarium.

Only available from Hammacher Schlemmer, this aquarium has three artificial jellyfish that move in the water amid seaweed and coral reefs while LED backlighting highlight their movements, providing mesmerizing ambiance without the maintenance required for typical aquariums. A silent, integrated motor generates gentle currents, causing the jellyfish to rise and fall in the water. You can choose specific light patterns from nine integrated LEDs that provide red, blue, and green highlights within the aquascape. The aquarium can be set up on a bookshelf or displayed on a tabletop. 13 2/3" H x 4 2/3" D x 17 1/2" W. (7 lbs.)
