Hi just thought I would share some photo's of my first lot of koi fry ever. I got them at about 1/2 to 1 inch long about 4 months ago. Some look massive compared to the others now and some even come close to the size of my 2 year old shop bought koi. Left - 6 month old koi Right - 2 year old koi These 2 are the same age from the same parents and look at the size difference. Another lot from the same parents at roughly the same size. Largest and smallest 6 month old koi. Selection of koi fry. The one in the middle is a 6 month old koi, the bottom is the smallest of the 3, 2 year old koi and the top is 1-3 year old koi. Lastly we got some larger koi from an auction. 12-14 inch Showa 18-20 inch Ogon, has long fins and tail could possibly be a butterfly cross.
