SereneScreen Marine Aquarium is a realistic, high-definition screensaver that converts your computer screen into a vibrant, colorful saltwater aquarium. You can choose from 27 different exotic fish species--from the Addis Butterflyfish to the Yellow Tang--and SereneScreen can display up to 30 fish at a time, with an easy interface for creating and customizing your own sets of fish (including an option for random species). You also have settings for auto-panning, frame-rate, Music playlists, and a bubble column (from a virtual aerator, with optional bubble sound).
