I guess I have always thought that reflections could be done the way they have been done on Playstation 1, Dreamcast, and other systems that do not have Shaders: Software emulation.
Gran Turismo was the first driving game for the Playstation that had reflections. They were reflection textures that were mapped onto each car.
If two more textures were added to each fish, one which responded to an invisible orange light to the LEFT of camera, and one which responded to an invisible blue light to the RIGHT of camera, I wonder if that would come close to looking as good as DirectX 9 shaders?
