Aqua Real 1.3.2 is a program that will simulate a 3D aquarium on your PC monitor. Through the Settings window you will be able to choose the fishes you want to see (up to 5 different types), the foreground and background colors, the location, amount, type and sound of the bubbles, if you want a frog or not. In the full version you can choose a musical background from an mp3 file on your hard disk. You can save your settings, or load your already saved settings. You can choose an aquarium from the available list (only Coral Reef in the demo version). The built aquarium can be used as an animated background for your desktop (or Active Desktop), replacing the static image you have. You can make changes on the background by pressing the right button of the mouse anywhere on the screen.
If you choose the second icon, you will be able to feed the fishes. They will go wherever you click on the screen, to eat the food you will be throwing. You can also see the aquarium in a window on the screen, or at full screen, without using it as a background.
