Marine Aquarium 2.6
One of the best known screensavers. The fish are true Direct3D objects, not simple bitmaps being dragged across the screen as in most aquarium programs.
The downside: the demo version lets you admire three fishes only; after registering the screensaver, seven fishes become available (and you can choose them among 26 species of tropical fish).
