Koi Types
Tancho Goromo
Tancho Goromo are just like regular Goromo, but they only have
a pattern on their maruten spot,
the pattern on the head. Tancho
Goromo's are very rare, if you see one, buy it. These do not come
around very often.
The skin should be very white and the maruten spot should be symmetrical.
The
maruten spot should sit between and slightly behind the eyes.

The Tancho Mystique:
The Tancho Koi, the ones with a nice head pattern, are one of the Japanese'
favorite types of Koi.
It is because this pattern looks like their national flag and
the red
crowned crane (Grus japonensis). Every Koi collector needs at least
one Tancho in their collection.
