I have two assorted Koi I got a couple of years ago as little fingerings.
One was silver and one was pale yellow which I hoped would turn more golden as she grew up. The silver one's fins turned red and he got darker edging as he grew. And he has rows of those huge thick scales down his sides. The above dragon reminds me so much of him. I hoped we would get a golden one as well as my little yellow Koi did indeed turn a gorgeous golden color as she got older. And tonight we got her as well! ^_^
