Well I found the Screensaver engine inside the System folder Library in System/Library/Frameworks/ScreenSaver/framework/Version/A/Resources/ScreenSaverEngine and set it for Best Quality in the ATI panel and it fixes the Jaggies in the Screensaver too!!! I also did it for the application SaverLab which lets you run MA as a desktop background and it works there too even though it doesn't for BackLight2.0 which in another desktopsaver app. I'm totally happy and thrilled now and the best news is that this doesn't seem to slow down the computer more or use more CPU or anything... it just makes the fish look great at last. I hope this info helps all the other people that may have Jaggies here.
