Koi Fish Explained 

koi Fish 

The koi fish is also a type of carp fish; although this fish can be seen worldwide, the Koi is seen as an exceptional fish because of its coloring and lineage. It is also a freshwater fish.

The Japanese take koi breeding very seriously. The Koi fish represents “affection” or “love” in Japanese; it symbolizes love and friendship in Japan, among many other symbols.

Each breed has its unique and beautiful patterning, scales, and color.

Are koi fish expensive? 

koi fish

Koi fish is attributed with so much value and can be worth millions of dollars; at the All Japan Koi Show in 2017, the most expensive koi fish sold was worth 1.8 million dollars.

We already know how particular the koi fish is because of their unique coloring and lineage.

Many said Japanese koi fish is more expensive than Koi sold in the US.

The Japanese overseas demand is on a rapid increase because it does not only attract attention from within Japan but also from foreigners abroad.

In places like Europe and America, the number of people who build majestic backyard ponds in their gardens and those who raise them as pets like they do dogs and cats has increased.

Koi fish Size – How big does it grow

The koi fish’s growth depends on what it feeds on and how well the water in the koi backyard pond has been filtered and cleaned.

If water has been changed regularly or at least once a week, a two-inch Koi can grow up to twenty-four inches in two years.

Although some koi fishes are slow growers, and some are bred to get huge, only certain breeds of Koi get that long.

Feeding them high protein growth food in Springs, Summer, and fall can increase their size, but during the winter months, it is not good to give them such feeds since they cannot digest food because their metabolism slows down so much that they do not need to be fed for months and will still grow fine, as long as the water remains clean.

Some choose to change the water on warm enough days during the winter, at least every two weeks.

So, the growth and size of a koi fish can be determined by what it has been fed.

In many fish species, stunting happens when they are kept in spaces too small for average growth.

The stunting phenomenon is not fully understood, and some fish still grow large for whatever space they are kept.

But, on the other hand, some fish grow big enough that its body is jammed into the glass no matter what position it tries to assume. (That is a cruel thing to do to any animal.).

So, a fish might try hard to grow as nature intended, but the consequences of restricting their space can be severe for the fish. Since a Koi can grow more than three feet in length, keeping one in the usual small-sized indoor tanks is not right.

Koi fish life span

Koi fish usually live 20, 30, or 50 years in length. Japanese Koi typically grow up to 22 to 26 inches, while Jumbo Koi usually grow between 34 to 36 inches.

But all Koi has indeterminant growth, which means they grow throughout their lives, so the longer they live, the bigger they get.

Like many fish and reptiles, a big koi is an old koi. As for how long it takes them to grow to adulthood, it can take them ten years to grow from fry to a 40-pound adult.

While, on an average, the Koi Carp have a good lifespan of roughly 40 years, the Koi carp with the most extended lifespan in the world is the one kept in the house of Mr. Koshihara in Shirakawa Village, Kamo County, Gifu Prefecture, who was born and raised in Japan.

The carp was renamed “Hanako,” and it is said that this carp lived up to 226 years.

Hanako has lived since the Edo period, and the Koshihara family has taken care of her for seven families.

Because this carp averaged a lifespan more than ten times a carp’s average lifetime, in 1983, the Guinness Book of World Records gave it recognition.
