Koi are often called “living jewels,” and for good reason — their vibrant colors, unique markings, and graceful movements make them captivating additions to any pond. Over centuries, koi have been selectively bred into dozens of distinct varieties, each with its own name, origin, and aesthetic appeal.

Whether you’re a beginner admiring your first koi or a seasoned hobbyist fine-tuning your collection, understanding koi varieties adds a rich new layer of appreciation to the hobby.
