Super cool light!! This will make any aquarium a showpiece. The awesome bubble stone with the lights in the center really bring my aquarium to life. The light colors change automatically, but slowly as to not freak the fish out. it is thin and can be buried in the rocks to not show the black casing. The electrical wire is thin and does not really show itself much. I buried the cord under the rocks and brought it up and out in the corner. It also comes with the tubing to hook to the air pump. The bubble stone is about an inch wide all the way around the circle. The circle is about 4 1/2 inches across. I am adding a video so you can see it lit up.
