Actually, koi fish that live in ideal conditions live on average up to 50 or even 60 years.

In some cases, the age of koi fish is much longer than that, maybe over 90 years like parrots, and the oldest example of koi fish Hanako from Japan which can live more than 200 years.

While the average beginner who keeps koi fish, the age of the koi fish only reaches 3-5 years.

Why is it so short?

Because most people, especially beginners, don’t know how to care for koi fish, and in the end, they kill the koi fish. Meanwhile, the age of koi fish kept by professional collectors usually reaches around 15-25 years of age.

Here are some factors that affect the age of koi fish:

Place or area of ​​the pool.
Water quality
The location factor or pond area and water quality are the main factors that greatly affect the age of the koi fish that we maintain. Poor water quality can cause premature death of koi fish. We don’t know for sure, but if they lived in a wider pond, they could have lived for another 20 years.

According to Dragon Fang, a professional koi collector, and owner of the Dragon Koi Center in Jakarta, “Koi fish can live long if the pH of the water is neutral and free from harmful substances such as chlorine and sulfur. In addition, the water must contain a lot of oxygen. “

Then what is needed to keep pool water neutral PH? One of them is using a filtering technique, so the owner does not have to clean the pool every time but only cleans the pool filter machine.

The benchmark that can be used is a filter used for one cubic of water containing 5 koi measuring 50 cm which is cleaned once a month. In addition, the owner must adjust the size of the koi fish to the size of the pond, so that the pond is not too small for the koi fish.

That’s an illustration of the age that koi fish can reach. It turns out that koi fish can live for hundreds of years as long as they are cared for and cared for properly, especially the size and cleanliness of the pond which is their main place of life.
