Today domesticated goldfish are distributed world-wide. We can see the results of this centuries-long endeavor in the wonderful colors and shapes of goldfish today. The majority of the fancy goldfish were developed by Asian breeders. By the 1500s, goldfish were traded to Japan, arriving in Europe in the 1600s and America in the 1800s. Goldfish were originally developed in China. However, recent genetic research points to C.
