This stunning animated 3D aquarium screensaver has lots of fish and a wonderful underwater scene. Options include 4 different ways to exit as well as multi-monitor support.Since it's a regular free 3D screensaver for Windows you can set it up in no time, all you have to do is grab it's installer and run it. Pretty easy and self explanatory, at least I tried to make it as user friendly as possible. To make sure this fish tank screensaver is your default windows 7 away from keyboard animation simply right click with your mouse on your desktop, select properties and that's it.
