11 Koi Fish Types For Your Backyard Pond

1. Gosanke Koi

Gosanke koi

Gosanke koi fish are a variety of koi that includes the Kohaku, the Taisho Sanke or Taisho Sanshoku, and the Showa Sanshoku.

Gosanke koi are distinguished from other koi by their white patches, which are typically located on the head and neck. You can also see them with red and black colorings. Gosanke koi are also larger than most other koi, reaching lengths of up to three feet.

While Gosanke koi are not as popular as Kohaku koi, they are nonetheless prized for their stunning appearance. Gosanke koi are also known for their longevity, with some specimens living for over decades.

2. Kohaku Koi

Kohaku koi are a type of Japanese carp that are characterized by their white bodies and red markings. They are a popular choice for koi ponds, and they can range in size from three inches to three feet.

Kohaku koi are also known for their long lifespan; some koi have been known to live for over 200 years, though most only live for decades. It depends on where they come from as well as their genes, diet, and environment.

If you’re thinking of adding Kohaku koi to your pond, there are a few things you should keep in mind.

First, Kohaku koi are best kept in groups of five or more; they are social creatures and do not do well when isolated.

Second, Kohaku koi require a diet of live food, such as worms or insects.

Finally, Kohaku koi prefer cooler water temperatures, so you’ll need to provide a cozy spot for them to hide away from the sun.

With a little bit of care, your Kohaku koi will thrive for many years to come.
