koi varieties - gosanke
What makes koi keeping so exciting is the fact the fish come in a great variety of colour's which provide endless combinations of colour arrangements There are 13 recognized classes, based on a set of different characteristics including colour, pattern and scale type. Unique koi with new colour and pattern combinations arise from time to time
Of course everyone has their favorite, but Go-Sanke are the most popular. Kohaku, Showa Sanke and Taisho Sanke are the 3 varieties that comprise this group and dominant most collectors ponds
The picture right illustrates Maruzome Kiwa. That is when the edge of the red [beni or hi] follows the scales and takes their circular shape. Sashi, the trailing edge, is a really good indicator if a koi is still developing or if the colour is finished
Kohaku
Sandan Kohaku
This koi has 3 distinct patterns of red so it is a 3 step kohaku. Sandan means "3". This is a very nice fish. Classic type of pattern, with an incredible tail tube and conformation
Yondan Kohaku
This 4 step koi has a more interesting pattern, particularly the head. The white cloudiness that appealers on the head and shoulder looks like a costia infection
Maurten Kohaku
The maruten designation for this kohaku comes from the round beni located on the head. This is a very full pattern with a lot to look at, very nice tail stop
Taisho Sanke
Taisho Sanke
Sanke have a beautiful elegance many people love. The sumi can be placed on the white skin [called Tsubo Sumi] or it can appear on the beni as "Kasane Sumi"
Doitsu Sanke
The Doistu Sanke [bottom] is a scaleless fish. This makes for exceptionally sharp edging [kiwa] of the colours which is quite attractive
Gin Rin Sanke
This is an exceptional fish that almost looks to perfect to be real. The sumi steps are placed like stepping stones in a amazing arrangement
Sanke should have good underlying kohaku patterns, with a nice accent of sumi on the shoulder. Black should not appear below the lateral line and of course, confirmation is everything
Showa Sanke
Showa Sanke
This is a very nice showa. Clean pattern without flecks of sumi scattered about with a nice underlying kohaku pattern. The sumi should join on the head
Kindai Showa
This newer style type of showa features less sumi [black] than the typical older style of showa. This is a full bodied fish making the fins look a little undersized
This showa has very nice motoguro [black pec fin joints]. It also look interesting on the head with the sumi starting to come through to form a nice menware/hachiware pattern
