Koi Types
Shusui
Shusui are the mostly scaless verion of the Asagi. There is
usually one row of dark scales on top and
one row along the lateral line.
Check all over the Shusui before you buy it to make sure that it
has a
complete row of scales. Also, make that they are straight and do not
distort the look of the Koi.

Where did Shusui come from?
In the early 1900's, the breeders took the mirror carp from Germany and
crossbred them with
the regular Koi to create two new types, Koi with rows
of large scales and Koi with no scales at
all. Shusui were the product of mixing a German mirrored carp with
an Asagi.
