PetFish - Version 3.0 Did you know there are lots of fish living in the cyber-ocean? Now, you can invite those fish one by one to your desktop by PetFish Collector. The fish continues swimming even when you are using other applications, or surfing internet. When you turn on ScreenTeaser(R), it moves around windows and icons on the desktop when your computer is inactive. You can feed it too. Each fish has different personality and shows different responses to your interaction with her. Download our sample program.
