KOI

Koi are colorful, ornamental versions of the common carp, known for their vibrant colors and patterns, which are a result of selective breeding. They are typically kept in outdoor ponds as decorative fish and are native to various freshwater bodies of water around the Black, Caspian, and Aral Seas. Koi can grow up to 3 feet long and live for several decades, with some living over 100 years.
