Sim Aquarium is a software that lets you experience the beauty of a coral reef aquarium on your computer screen with realistic 3D graphics. It features swimming fish and sea creatures in a 3D environment that includes a living reef and live clams.

Sim Aquarium allows you to populate your aquarium with up to 100 fish from a selection of 30 highly detailed species of fish, each with complex swimming behaviors and artificial intelligence. You can interact with your fish pets by using your mouse to touch them by their tails or noses. They will stop to inspect or dart away into safety, just like real fish! You can also feed your fish, but unlike real fish, they won't turn upside down and float up if you forget to feed them regularly.
Features of Sim Aquarium include live desktop wallpaper mode, full interaction with the fish and their environment, realistic anemone tentacles physics and fluid simulation, and advanced graphic effects like fish iridescence, raytraced light caustics, and complex water surface.
Overall, Sim Aquarium is an excellent software for those looking for a realistic underwater experience. With its intricate 3D scenes, highly detailed fish species, and advanced graphic effects, you'll feel like you're right in the middle of a coral reef.
