Koi fish (Cyprinus rubrofuscus) are a domesticated variety of the common carp. Their history dates back to China over a thousand years ago, but they gained prominence in Japan during the 19th century when selective breeding techniques were developed to enhance their colors and patterns. Today, koi breeding has become an art form, with many varieties available, each distinguished by unique colorations and markings.

Caring for Koi Fish
Keeping koi fish requires proper care and maintenance to ensure their health and longevity. Some key aspects of koi care include:
