This is the LED-lighted desktop oceanarium with four synthetic jellyfish that provide mesmerizing ambiance just like their real counterparts. Providing a tranquil water vista without the maintenance of typical models, the 2.64-gallon tank has a silent motor that generates gentle currents, causing the jellyfish to rise, fall, and undulate in the water. Ideal for placement in an office, study, or children’s bedroom, it has 36 LEDs that can be set to five solid color displays or three light shows. Plugs into AC with included adapter and automatically turns off after four hours. 133/4" L x 133/4" H x 41/4" D. (5 lbs.)
