Species often confused with {name}
Common Carp
Cyprinus carpio
Key differences: Koi are selectively bred ornamental varieties of carp. While genetically very similar, common carp typically have a duller, more uniform coloration (often olive-brown to golden-brown) and lack the intricate patterns and vibrant hues of Koi. Common carp also tend to have a more elongated, less 'chunky' body shape than some highly bred Koi varieties.
Goldfish
Carassius auratus
Key differences: Goldfish are generally smaller than Koi and lack barbels. While they also come in various colors and fin types, their body shape is typically more rounded or egg-shaped, and their finnage can be much more elaborate (e.g., fantails, bubble eyes) compared to the more streamlined fins of Koi. Goldfish are also a distinct species from carp.
