Offered only by Hammacher Schlemmer, this is the LED-lighted desktop aquarium with two synthetic jellyfish that provide mesmerizing ambiance just like their real counterparts. The aquarium has 18 LEDs (six each of red, blue, and green) that automatically gently change color, causing both jellyfish to “react” by glowing yellow, purple, aquamarine, blue, and red as they float within gentle currents generated by the unit’s silent, integrated motor. Manual color selection enables one color display. Set up on a bookshelf, tabletop, or desk, the aquarium plugs into AC; automatically turns off after four hours. Easy to set up. 13 3/4" H x 5 1/2" Diam. (1 1/2 lbs.)
