The 1st kohaku has flakey red and will most likely loose it.
The 2nd kohaku is too bald , its red is better than the previouse one but its still eina...its difficult to say but i think it might loose some aswell.
The 3rd Kohaku is the best of the 3 kohakus although its also a bit bald.
The Shiro Utsuri might have a body shape problem but it might be because its still so small and that it just ate. The colours on it looks nice and strong. I like the head marking and sumi in the tail. The pectorals are propably going to be stripy and not have motoguro.
The 2ns shesui is ok, missing part of its zip tho.
The ogon looks nice.
Is that realy an asagi? Gin rin silver and yellow?
The last ogon is nice aswell.
I like the netting on the Ochiba but it think it might be to dark, not sure as i dont realy know these variates. The ochiba really left an impression on me, lets see how it develops.
Overall a nice collection, although there are a few problems here and there.
DAVID, you need to learn to do over the shoulder photos of kois that way one gets an beter overview of the body shape, length, fins, colours and scales. It takes a bit longer and is a bit more difficult but in the end one can see its development better. Its difficult to judge kois from photos where they are doing the jive. Heres a technique i learned from Cristie Van Zyl. Bowl the koi. Take the bowl and put it on a table or on the floor. Make sure that all the fins of the koi is covered with water. Throw a towl or piece of cardboard over the bowl. Give the koi 2-3min to relax. Ask your wife to lift the towl or cardboard slightly while you peek in with the camera. Have the flash on and camera on fast shutter speed or ISO - wait for the koi to swim towards you. Aim the focus just infront of the dorsal fin. Make sure your angle is not to shallow and shoot.
Check the pictures before releasing the koi!
