I'm stupid. I should count before I complain.
You're right, there are 8 fish there! And there are 8 spots to fill in the preferences tab. It was just a bit confusing since a greyed-out area annoucing that the 8 fish is for widescreen only made me think that was an empty and unaccesible parameter.
Nevermind.
Starfish definitely needs to stay put though.
