only 7". I do not know the breeder, but i'm sure it was Japanese, it was some name with the K in begining that i see on the box . in a tank about 200 fish, there is a customer ahead of me he pick 10, some how he does not see these fish. I think he need KOIBITO member. The second showa in real look better than the the first one, i still do not know why after long minutes of inspecting them 2, i think probably because of the skin hi quality on the shoulder without any sumi. hum, still have to analyse and learn.
