Koi fish, admired for their vibrant colours and graceful movement, hold significant cultural value, particularly in Japan, where they symbolise perseverance, strength, and good fortune. Belonging to the Cyprinidae family, these ornamental carp are selectively bred for their striking patterns and hues, ranging from fiery reds and oranges to serene blues and whites. Koi ponds, designed to create ideal conditions for their growth, are cherished in gardens and landscapes around the world, offering peaceful spaces for reflection. With lifespans that can extend for several decades and some reaching impressive sizes, Koi continue to inspire artists and enthusiasts, influencing numerous works of art and literature.
