What is Fish!? Fish! puts a variety of undersea life on your desktop, and also offers a screen saver mode. Download Fish! for Mac Architecture
System Requirements From Mac OS 6.0 up to Mac OS 7.1 The desktop animations only work in System 6. However, the screen saver still works in Mini vMac (II) with System 7.0.1 or 7.1.1. In Basilisk II (with System 7.5.5), the Fish! control panel causes the OS to hang while booting. Emulating this? It could probably run under: Mini vMac |
