thank aquitori, you have brought so may interesting subject to the forum that we all enjoy very much. What kind of the red is the best? that is the question that i brought to Brett when i was at his farm couple month ago (i live 45 minutes away from his farm). he turn around and after a while of searching in his big tank have hundred of kohaku, pull out one to me to see.
it's an orange deep red! he say that all the judge like this orange red because in the future it will not fade, further more, it shines when it goes near the water. i look very carefully, it not purple red, it not red red. it a deep orange red and shine! i completely agree with him. it's not cheap then. 8" for 350! i finally settle with another one 6". until now in my pond, that the most beautifull kohaku that i have (it's the most expensive 6" too) Later , i notice that the skin was thicker with time, and tight! at the edge it look sharp! (kiwai?) i been looking for another one since then at mamy places, but not. finaly i found one at an simple pet shop. it small 4" but orange red ($12), i bought just to make a gamble. because i see the skin was tight! it turn out several week after, a shinning wet orange red small kohaku. Keep looking, with luck you might find one.
