This is the Hypnotic Jellyfish Aquarium with LED lights and 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 ambiently within gentle currents generated by the unit’s silent, integrated motor.
