This is one of the best examples of how our Sanke line develop from end of the first summer at around 5 months old and 10cm through to 3 years old and 60cm. First thing is how the soft orange pigment has developed into a strong deep shiny red. The edges of the pattern have become more defined and refined giving clean clear boundary to the individual colours.
The black has receded but is still present in each area it was before while developing a depth and shine. White back ground has also become much thicker and brighter giving a strong impression making this male koi look stunning.
