To help develop and maintain healthy coloration, Tancho koi are often fed diets with color enhancers, such as those containing spirulina or krill, as well as those with ample (>30%) protein to aid in proper growth. These are of lesser importance if you don’t wish to show your fish at shows. Otherwise, though, the dietary needs of Tancho koi are much the same as most other koi.

Oftentimes, the exact criteria are adjusted based on the judges, but generally speaking, Tancho koi are held in fairly high esteem whether in Asia, the UK, or the US due to their uncommonness. Overall, there are generally a particular set of guidelines that are followed when appreciating and judging Tancho koi. These guidelines will differ depending on the particular type of Tancho, whether Kohaku, Sanke, or Showa. General Guidelines for Judging Gosanke The “red sun” atop the head of a Tancho should exist high atop the head between the eyes. Any white should be bright and not off-white or yellowy.

"Examination of pair-duet stability to promote long-term monitoring of the endangered red-crowned crane (Grus japonensis)." Journal of Ethology 27.3 (2009): 401-406. On average, adult males from Hokkaidō weighed around 8.2kg (18lb) and adult females there averaged around 7.3kg (16lb), while a Russian study found males averaged 10kg (22lb) and females averaged 8.6kg (19lb); in some cases, females could outweigh their mates despite the males' slightly larger average body weight. Another study found the average weight of the species to be 8.9kg (20lb). [10] [14] [15] The maximum known weight of the red-crowned crane is 15kg (33lb). [16] [17] Among standard measurements, the wing chord measures 50.2–74cm (19.8–29.1in), the exposed culmen measures 13.5–17.7cm (5.3–7.0in), tail length is 21.5–30cm (8.5–11.8in), and the tarsus measures 23.7–31.9cm (9.3–12.6in). [14] Range and habitat [ edit ] The population of red-crowned cranes is split into a migratory continental population in Korea, China, Mongolia and Russia (with all birds wintering in Korea and China), and a resident Japanese population in Hokkaidō. [1] [43] [44] In 2020, winter counts recorded more than 3,800 red-crowned cranes (adults and immatures), including about 1,900 in Japan, more than 1,600 in Korea and about 350 in China. This indicates that there are around 2,300 adults overall. [1] Whereas both the resident Japanese population and the migratory population that winters in Korea have increased in recent decades, the migratory population that winters in China has rapidly decreased. [1] The main threats are habitat loss and fragmentation, but to a lesser extent also human disturbances near their nesting grounds, poisoning and poaching. [1]

The red mark on a tancho koi's head should be round and well-defined. The ideal size of the mark is about the size of a quarter. A Tancho Showa has the characteristic red sun marking atop the head between the eyes, with white on the rest of the head and body. Sumi can exist anywhere, even within the red spot. del Hoyo, J. Elliott, A. and Sargatal, J.(1996) Handbook of the Birds of the World Volume 3: Hoatzins to Auks Lynx Edicions, Barcelona The formation of the red spot on tancho koi fish is a result of genetics and selective breeding. Breeders carefully select and breed koi with a genetic predisposition for the single red spot. This intentional breeding practice ensures that the offspring will also have this distinctive feature. As a result, tancho koi fish come in various patterns and variations of the red spot, adding to their uniqueness and beauty. a b c d Klenova, A. V., Volodin, I. A., & Volodina, E. V. (2008).

If you are looking for a beautiful and unique koi fish, a tancho koi is a great option. These fish are sure to turn heads and bring you years of enjoyment. Yes, tancho koi are considered to be rare.

Additionally, tancho koi are often sold at a premium price, which makes them even more exclusive. The appreciating and judgement of Tancho traits is much the same as for they are for Gosanke koi in general, with, of course, a couple of specific added requirements.
