Key Differences
Koi are a domesticated variety of common carp selectively bred in Japan for their bright colors and decorative patterns. Carp, on the other hand, include a wider range of freshwater fish species, typically found in natural habitats and less vibrant in coloration.
Koi display a wide variety of color patterns, including red, orange, yellow, black, and white. Carp generally have darker, earth-toned hues that help them blend into their natural surroundings.
Koi are primarily kept in ornamental ponds for aesthetic purposes, often symbolizing peace and prosperity in Japanese culture. Whereas carp are generally found in natural bodies of water and are more commonly used for fishing or aquaculture.
Koi are specially bred and cared for, requiring high-quality pond conditions to thrive and maintain their colors. Carp, by contrast, are hardy and can survive in a wider range of water conditions due to their adaptable nature.
Koi varieties are recognized and classified based on specific color patterns, scale types, and body shapes. Carp have several species and subspecies but are not typically classified by ornamental characteristics.
