Not self-sinking. We tried to just shape it and drop it but it floats, we pinned it with a rock and the fish pulled it out. Now he just swims at will. It releases a lot of bubbles and my fish love to just sit in one of the curves and let the bubbles wash over them. But if you're expecting self-flooding, don't count on it.
