Seriously, photography is alot about balancing and compromising. For example, to 'freeze' a moving fish, you need a fast shutter speed, but in order to do that, you need to open the aperature more to get the equivalent ammount of light, which in turn may blur the background. Or, you can add flash to increase the light, but flashes have a 'range' as well, so that may not be an option at longer distances to your subject. It's all about getting the light you need for the picture you want to take.
