Ive been thinking about trying a nano reef setup and I went to my LFS to look ask some questions about live rock when I saw a new display that they had set up. It has to be the worlds smallest nano reef. It was about 3 inches deep and 4 inches wide by 4 inches long. It had what looked like an itty bitty desk lamp attatchment for light and a baby HOB filter. Inside was 1/2 lb. of live sand, pound of live rock and some sort of shrimp. I thought it was kinda silly and neat at the same time. They wanted 65 bucks for it. I am gonna go back tomarrow and see if they will let me take a picture of it, plus I just want to look at it again.
