Hi guys
Please look at the development of the below fish. They seem to be losing a lot of their color (both hi and sumi).
What could be the cause of this or is it just part of the normal development that koi undergo? I know koi's pattern changes a lot but I haven't seen this amount of change in such a short time period...
1) Sanke
Pic1 = 16cm (taken Dec 09)
Pic2 = 24cm (taken yesterday)
2) Doitsu Ochiba Shigure
Pic1 = 10cm (taken Dec 09)
Pic2 = 23cm (taken yesterday)
3) Shiro Utsuri (won't mind a bit of sumi disappearing on this one)
Pic1 = 32cm (taken Dec 09)
Pic2 = 51cm (taken yesterday)
