Koi (or Nishikigoi) are vibrant, ornamental varieties of domesticated common carp (Cyprinus rubrofuscus) traditionally kept for decorative purposes in outdoor ponds and water garde ns. First bred by rice farmers in Niigata, Japan, during the early 19th century, they are celebrated globally for their striking colors, complex scale patterns, and deep cultural symbolism. Key Facts About Koi Fish Lifespan: They average a lifespan of 40 years, but can live much longer under optimal conditions. The oldest verified koi famously reached nearly 230 years old. Size: Healthy adult koi can grow up to 3 feet (90 cm) in length, requiring large, deep ponds. Diet: They are opportunistic omnivore feeders that eat algae, aquatic plants, insects, and commercial floating pellets. Value: Prize-winning show fish with flawless genetics can command astronomical prices, sometimes selling for over $1 million at Japanese auctions.
