A Symphony of Koi

The vibrant assembly of fish in the water is a gathering of Koi (Cyprinus rubrofuscus), a domesticated variety of common carp. As a marine biologist, I find their brilliant and diverse coloration to be a testament to centuries of selective breeding. These fish, often referred to as "living jewels," are a cornerstone of Japanese culture, symbolizing luck, longevity, and perseverance.

The pond is teeming with different color varieties, including the striking kohaku (red and white), the elegant sanke (black, red, and white), and the bright yellow ogon. Unlike their wild ancestors, which are a dull brown, Koi are celebrated for their unique and intricate patterns, with each fish a distinct work of art. Their serene movements and social nature make them a popular feature in outdoor ponds and water gardens around the world.
