Aquarium Gadget

Aquarium Gadget is a simple, fun widget that displays a virtual aquarium on your desktop, designed for users who prefer fish as house pets. It is easy to install and set up.
The frame of the widget resembles a round aquarium; you can move it to any position on the screen with the help of the mouse cursor.
The aquarium contains an animated goldfish and some algae. The image quality is not excellent and the animation does not run smoothly, but we must take into account that Aquarium Gadget has not been updated for a long time, and that it was primarily designed as a simple utility after all.
Unfortunately, the tool does not comprise any options of its own. For example, you cannot add more fish into the aquarium or change the colors. In this case, you can only configure the settings provided by the operating system by default. Therefore, you can make the frame stay on top of other windows, as well as set its opacity level to a preset value which ranges from 20% to 100%.
The widget is very light on the system resources, since it requires a minimal amount of CPU and system memory. It has a good response time and works well, without causing the operating system to hang, crash or pop up error dialogs. All in all, Aquarium Gadget is a simple gadget which displays a small aquarium on the screen.
