Fish are fascinating creatures that we can admire, keep as pets, and sometimes enjoy for dinner.
There are lots of interesting facts about fish that we can learn.
One question that many people have is whether or not fish can see water.
We have all the answers about this and some other interesting information about fish.
Can Fish See Water?
Fish cannot see the water.
Just as humans cannot see air, fish cannot see water.
Since the fish’s brain is continually looking through water, it starts to filter out the water.
This has happened through years of evolutionary progress and change.
Humans can sometimes see smoke in the air, but the brain has filtered out having to deal with processing all of the air that we see.
This is done so that the brain can use its power on other more important things, whether it be life functions or something that requires focus and concentration.
If the brain were continually having to think about the air and processing all of it, there would be no way to function.
Fish can’t see water so that they can function and do what they need to do in the water.
Can Fish See Humans?
If you have a pet fish, you may be wondering how much your fish is able to see you.
Of course, talking to and making friends with your fish may seem like fun, but do they even see you?
Most studies conducted have shown that fish can, in fact, see humans.
Researchers have even discovered that fish can recognize a familiar face as opposed to one that is not familiar to them.
This is interesting and can change how people think about fish and their overall intelligence level.
Pet fish have not always had the same regard that a cat or a dog or a bunny might have enjoyed.
However, the more we learn about fish and the way that their brains work, we tend to have a bit more respect what they are capable of.
How Do I Know If My Fish Is Happy?
Another interesting question that people have about fish is whether or not they are happy.
Of course, if you are a responsible pet owner, you are going to want to make sure that any animal in your care is happy.
It is essential to ensure that the animal is safe and has shelter, but there is an importance that humans put on happiness.
Although fish can’t communicate with us, they can show us some signs that they are indeed happy.
Here are a few things that you will notice when your fish is showing signs of being happy.
1. Swim Actively
Fish that are happy are going to be swimming around and exploring their tank.
They will be active in their swimming, and they will not just stay on the bottom or hang out in one spot.
The fish that is swimming around actively will end up exploring the tank and actively looking and learning.
This is a sure sign of happiness in your fish.
If you notice the fish starts to spend time in just one section of the tank, chances are they are not feeling well, or there is some other kind of problem.
Fish owners need to constantly pay attention to the water and to the other fish that are in the tank to make sure it is a safe balance for their finned friends.
Another thing to watch for is if your fish is continually hiding.
If the fish hides behind the obstructions in the tank, they may be worried about another fish and the potential danger from that fish.
Don’t let the fish live like this.
Make sure that you don’t have issues with one fish causing problems for another.
2. Eating and Being Hungry
A happy fish loves to eat.
Fish that are happy will be excited for mealtime, and they will swim to the surface when you come to feed them.
A fish that does not feel good or is not happy will not pay attention or care when you add food to the tank.
This is a sure sign that there is a problem.
Overall, fish are looking to survive and thrive, and eating is a major part of this process.
3. Coloring and Look
When you first get a fish, you should spend some time getting to know what it looks like.
This will help you to make sure that you recognize any changes and help it should it have any issues later on.
If you know that your fish has a certain coloring, you will be able to notice if that were to change.
If the coloring of the fish changes for some reason, it could be that they are unhappy or sick.
You will also notice that their eyes may bulge a bit, and this is another warning sign.
Getting to know what your fish looks like and paying attention to the details will only help you take better care of them.
If you notice white spots, fins that are torn or ragged, and eyes that don’t look quite right, it is a good idea to look into your fish’s overall health.
These three signs are excellent indicators that your fish is happy and enjoying their life.
Can a Fish Hear?
Since we filled you in a bit on what a fish can see, let’s now look at whether or not a fish can hear.
Many fishermen wonder about what fish can hear as they want to make sure they are not scaring fish away by driving their boat into an area that they plan to fish.
The bottom line is that fish can hear, although they can’t hear as well as humans.
Fish are able to hear mostly low frequencies.
This means sounds that are lower in pitch, something like a bass guitar or a boat engine.
Most fish cannot hear the higher pitched noises.
Of course, there are a few exceptions to this rule, and some fish can hear even better than humans do.
The bottom line is that, if you are trying to sneak up on a school of fish, you are probably going to want to turn the boat engine off.
Chances are the fish will be able to hear your speech, the engine, and maybe even the radio that you have on.
If you have a pet fish, this means you may as well start talking to it.
Since the fish can hear you, it may get used to hearing your voice.
Do Fish Feel and Think?
We might as well cover all of the senses that go along with fish.
Feeling and thinking are two things that many people will debate when it comes to fish.
Some people believe that fish are capable of feeling and others think there is no possible way.
Most studies that have been done show that the fish do not feel pain.
Their brainpower is simply not big enough to process the pain, and therefore they don’t feel it.
However, there are some people out there who will argue that point, and often for a good reason.
Whether or not fish feel pain is a bit of a personal and a bit of a scientific decision.
As far as thinking goes, most will agree that fish don’t really think.
They are able to survive and to look for food, but they don’t think and plan their days out the way that a human would.
When you study science, there is a correlation between the size of a brain and the power that the brain has to think and feel.
Most fish don’t have a very large brain and aren’t able to plan out their thinking.
Conclusion
Fish are interesting creatures that are quite capable of some exciting things.
The fact that fish cannot see water should come as no surprise.
If humans can’t see air, it makes sense that a fish’s brain can filter out the water.
If humans lived underwater, chances are they would eventually learn how to filter out the water as well.
Of course, this would take many generations and the process of evolution, but it could become a possibility at some point.
In the meantime, we will go about our lives seeing the water and fish can get a break from having to filter out those sights.
