This paper addresses the similarities and differences between the way that humans see and the way that goldfish see. It examines how adaptation behavior in both humans and goldfish has developed the vision that they have overall as a species today and how, although they may see very differently from one another as a species, there are specific reasons for the type of vision that each species has.
From the Paper:"Vision that is seen in the goldfish may not seem important to many people, but it is actually quite fascinating in that it is much more developed than most people would expect it to be for the size and apparent intelligence of the creature. Overall, goldfish have developed full-spectrum vision so that they will be able to see the micro-flashes of static electrical charge and bio-luminescence that appear when a creature hunting with sonar sends sound waves through waters rich in micro-fauna in order to search for its prey (Schaerer & Kirschfeld, 2000). This full-spectrum vision has also proved to be very effective in sensing many and various tell-tale signs that come from the bow-wave that a rapidly moving predator makes as it cuts through the water (Schaerer & Kirschfeld, 2000)."
