Koi are ornamental varieties of the common carp, selectively bred in Japan since the early 19th century from utility carp originally introduced to the country for rice paddy aquaculture. The named koi colour varieties recognised today include the kohaku (white with red), taisho sanke (white with red and black), showa sanshoku (black with red and white), and many others within a structured judging system developed by Japanese koi associations across the 20th century. Premium individual koi can sell for tens of thousands to over a million dollars in competitive show fish auctions, with the value driven primarily by colour purity, body conformation, and judging-criterion-specific features. Koi can live exceptionally long lifespans for fish - the famous koi Hanako of Japan was documented to have lived 226 years, verified through scale-ring analysis, making her one of the longest-lived vertebrates ever recorded. Most koi in well-maintained outdoor ponds live 30 to 50 years. The species can grow to substantial size, with adult koi commonly reaching 60 centimetres in length and large specimens exceeding 1 metre. This tee puts a bold koi fish print on soft cotton for girls who have found these ornamental carp.
Cut from 100% cotton with a ribbed knit collar that holds its shape wash after wash. Taped shoulders prevent the neckline from distorting over time, and dual side seams maintain the garment structure consistently. The koi fish print is applied at high resolution so the ornamental carp silhouette comes through accurately and stays vivid after machine washing and tumble drying.
This tee works for koi keepers, pond fish enthusiasts, and any girl who finds the documented 226-year lifespan of Hanako one of the more striking examples of vertebrate longevity. It suits casual everyday wear, fish events, and any occasion where koi appreciation is worth expressing.
Machine wash cold and tumble dry low. The shirt runs true to size. Durable enough for regular use without fading.
Order yours and confirm the koi fish appreciation today.
