Tried to get a video of my male BD's belly spotting on the iPhone while doing a water change. He must be shy as he didn't go for the "full belly shot". By the way, the tank is wider than it appears in the video (36" wide). I have a plumbing pipe that runs down the side of the tank that I was trying to avoid in the video.
