I went to the Atlanta Koi Club Koi auction today. I placed bids on several fish but the prices were a bit higher than my planned budget. The prices compared to retail were very good. I will definitely go back next year.
I did win a nice Kojaku [updated] and a nice gin-rin long fin Kohaku for $75. Both are about 14 inches and are a redish orange and white tone. Nice large fish for the price. They are sitting in their bags at the moment acclamating to temperature. I prepped the pond by adding ick and parasite medication to make sure they have a good chance at survival.
Update: the Kojaku regular fin is a blend of Matsuba and Kahaku. He has a nice redish head and orange on his back with the dark scales of the matsuba.
He also has orange on his fins but the tips are white.
