Cats and dogs are the most popular pets because of their ability to bond with their owners and show love. They recognize and remember their owners after being apart for years.
But what about other animals? Do they have the same innate ability to form meaningful attachments with human beings? Do they experience genuine affection for the humans that raise them?Â
Can Koi Show Affection?
All over the world, people love owning koi ponds for their natural beauty. A well-kept koi pond can uplift any home or garden, with stunning koi fish swimming gracefully through the waters.
But koi aren’t just an ornamental showpiece. They are intelligent creatures, capable of learning and feeling, even if we don’t understand them.
It is widely believed that koi can recognize their caregivers, and there have even been scientific studies that aim to prove that very hypothesis.
Critics say that koi don’t recognize owners, but learn certain patterns of behavior based on following the same routine.
For example, if you feed your koi at the same time in the same spot every day, they will eventually learn to swim toward you. Is this because they’ve grown to love you? Or is it because they’re hungry, and you just happen to have food?
So, what is the truth? Do these popular pets recognize their owners or is there another explanation for their behavior? This blog will aim to explain if koi fish can show affection, and how they may do it.
What The Evidence Tells Us
Koi fish are highly sought after by enthusiasts and experienced breeders, not just for their stunning patterns and shimmering scales, but also for their calm personalities, friendly demeanors, and impressive intelligence.
Most people see goldfish as mindless creatures, with no capacity for thought, other than to swim.
On the other hand, many people think that koi may develop relationships with their owners and remember them even when they are not around.
Do these statements have any supporting evidence?
Research-Based Evidence
A team of researchers wanted to test whether or not koi possessed the ability to identify their owner’s faces. In the experiment, they separated koi fish into two different groups.
One group was shown images of their owners’ faces, while the other group was only shown images of strangers.
Koi fish that were shown photographs of their owners were more inclined to swim toward those images than those who were shown images of strangers, according to the study’s findings.
What this suggests is that not only did the koi recognize their owners, but they were interested in interacting with them, even without the promise of food. The study was published in the Journal of Animal Cognition.
Despite the evidence, some critics have been quick to point out that the experiment took place in a controlled lab environment, and is, therefore, not indicative of how pet koi may behave in captivity.
Anecdotal Evidence
Because koi raising is such an old and widespread hobby, many experienced keepers have developed anecdotal evidence to support the possibility that koi feel affectionate toward their owners.
For example, some koi fish owners claim that if they walk along the edge of their koi pond, the koi will curiously follow along, trying to get their attention.
However, the reasonable explanation here is that the koi are expecting to be fed. Other keepers even go as far as to claim that their koi will affectionately nuzzle into their hands, or enjoy being petted as a cat would.
Can Koi Be Trained to Display Affection?
Whether or not displaying affection comes naturally to koi fish, could they possibly be trained to do so? Some experienced koi keepers seem to believe so.
For example, the aforementioned study proved that koi can learn to recognize their owners. This is not an innate skill that koi possess on their own. It’s something that they have learned over time.
How To Train Your Koi to Recognize You
You don’t have to be an expert in koi raising or even a scientific researcher to train your koi to recognize you and get comfortable with you. It’s quite simple. The first step is to develop a routine around their daily feeding.
Start by feeding them every day at the same time, standing at the same spot in their pond. Remember, koi fish are creatures of habit.
This consistent routine allows them to fall into a sense of comfort that will enable them to trust you, and bond with you.
If you continue feeding them this way regularly, you’ll eventually notice that your koi eagerly swim toward you whenever you approach their pond. That’s how you know the first step of their training has been successful.
 The next step is to train them to eat their fish food right out of the palm of your hand.
Start by pouring some fish food out into your palm, and gingerly bring it to the surface of the water.
Tilt your fingers downward, so that your koi can reach their heads up out of the water and eat out of your hand. It’s important to remember that patience is key here.
You have to stay perfectly still, and allow your koi to take their time eating from your hand. If you make any sudden movements, you might scare away your koi, and it may prove difficult for them to trust you again.
Another factor to bear in mind is that no two koi are the same. They each have different personalities and temperaments. Some koi may be more eager to approach you, while others may be hesitant at first.
Don’t let this discourage you. After seeing their pond mates interact with you, it’ll only be a matter of time before the more skittish ones build up the courage to do the same.
The next step in your koi’s training is a real test of whether or not these creatures trust you.
Once your koi have learned to swim to you and eat out of your hand, the next step is to teach them to leap up out of the water to grab food out from between your fingers
To start, hold each piece of food between your fingers and allow a koi to eat it. Do this a few times, until the koi feels at ease. Then, gradually begin pulling your hand back, ever so slightly.
If the koi is hungry, it will try to follow your hand. With a bit of practice and a lot of patience, your koi will eventually leap up and grab the fish food right from between your fingertips.
Over time, slowly increase the distance between your hand and the water, to teach your koi to jump even higher. However, don’t try to go too high, in case you risk hurting your koi.
Expert koi raisers caution newer keepers from trying this trick. Teaching your koi to jump out of their pond may encourage them to do so even when you aren’t around.
One of your koi could end up banking itself on the edge of the pond, unable to return to the water. If you don’t notice this happening in time, the worst-case scenario is that your koi could die.
To avoid this, experts recommend installing a border around the edge of your pond.
How Do Koi Fish Show Affection Toward Their Owners?
It might be unfair to compare your pet koi to cats and dogs. After all, koi don’t have limbs to paw at you for attention, or tails that wag ecstatically when they’re excited.
However, there are other ways that your pet koi may display their affection for you, and as their owner, it’s important that you learn to read these signs.
For example, they may follow you along the edge of their pond as you move, or even jump out toward you to get your attention.
If you dip your hand into their pond, your pet koi fish may even swim up to you, and nuzzle into your hand, allowing you to rub and pet them.
On the other hand, if your koi are having trouble bonding to you, or don’t like being around you, they will make their displeasure known by skirting away and hiding behind plants and rocks when you approach, or batting at you with their tails when you try to pet them.
Now That You Know
Now that you know just how affectionate koi fish can be, what do you think?
Are you an experienced koi raiser? If so, have your pet koi fish displayed such signs of affection before? Or have you been able to train them to do so?
If you’re new to koi raising, does the knowledge that koi can be affectionate creatures entice you to get your own?
Koi raising isn’t easy, it’s important to do your research, and understand what you’re getting into.
As intelligent creatures, koi deserve the best quality of life we can give them, and raising them should never be taken lightly.Â
