Things are Not Always as They Seem: Theories about Why Fish are So Colorful

Have you ever wondered where fish get their color, both individually and by breed? No one knows with 100 percent certainty how fish obtain their color nor why fish are so colorful, but there are a few theories.

One animal that is similar to a fish in terms of the variety of color is a snake. It’s easy to see why snakes are so colorful; it’s a means of survival by blending into the grass, dirt, sand, and weeds. The need to blend into the environment is one obvious theory regarding the survival of fish as well. According to researchers, however, the reasons why fish are so colorful is probably much deeper than we know.

Possible Reasons Why Fish are So Colorful

In addition to using their color to hide from predators by camouflaging with the objects around them, there are several other theories and facts about why each fish has a variety of markings and each breed is different than the other.

Based on the findings of one scientist, Gil Rosenthal, the fact that they live underwater rather than on land has a lot to do with it. Things look much different underwater. It’s darker, but light comes from a variety of sources, and that light isn’t always the same. Therefore, fish need the various markings in order to:
● Identify each other underwater.
● Identify predators.
● Identify competitors within the same breed.

Have you ever wondered why fish are so colorful, like this lionfish is?Their vivid colors also tend to give them a fluorescent tone, which possibly allows allies to see them better.

Because fish live in different areas of the water, be it near the surface or deep in the coral reefs, they need to adapt to their environment, which is an additional theory about why fish are so colorful.

Another issue that factors into the equation is that humans can’t tell what fish see; truly, that would be almost impossible unless you were seeing through their eyes while they were still alive. The fish, therefore, might not even know how beautiful they are, but have their own methods of identifying each other that humans don’t quite understand.

It’s also possible that the spotted, multi-colored fish that we see looks like one plain, solid colored animal to another fish from a distance. It could be nature’s way of allowing fish to be identified by friends but hidden from foes.

Up-Close Admiration

When it comes to us as pet fish owners and aquarium enthusiasts, we simply reap the benefits that nature gives us. This is especially true for owners of reef aquariums, as fish that live deep in natural waters tend to have the most beautiful markings.
