Sorry I currently don't have any pictures because I don't have a camera. Although this is the video the seller placed on his page (http://www.youtube.com/watch?v=vh4zt...layer_embedded
). I've been letting it float around my tank and its still not sinking. I have 3 of them in my tank, but I had to sort of bury the bottom portion under the substrate, but it would be nice if I could stack them and just place it above the substrate.
