Personally I read about it along ago from a Linux magazine. It is a very friendly and interactive shell and what I like most is the tab-completion. For example:

• You are on the shell and you write "gt" and press tab it will show you all the executable files starting with gt like gthumb,gtbl etc.  
• You are on the shell and write "ls -"  and press tab it will show you all the parameters of ls.

The homepage of FISH is http://roo.no-ip.org/fish

If you are using Ubuntu Linux you can get on a terminal window and type the following:

>sudo apt-get install fish

It will be installed just like that! If you want to use it only sometimes just get on a terminal window and type fish. When you want to stop just type exit.

If you want to make it your default shell then you must do the following:

1. Get on a terminal window.
2. Check the /usr/bin directory. You can type "ls /usr/bin | grep fish"  or use Nautilus/Konqueror . If you don't find fish there then check the /usr/local/bin directory. It is important for the next step.
3. Type "sudo gedit /etc/shells" and add "/usr/bin/fish' as a new last line.
4. Type "chsh -s /usr/bin/fish".
5. Type "exit" in order to logout.
6. Get on a terminal window and the FISH will appear.

If you want to  get back to bash then type "chsh -s /bin/bash" and bash will become your default shell.
