How does a goldfish develop its colours?
The goldfish (Carassius auratus) belongs to the carp family to which the common carp or Koi fish belongs. It was originally domesticated as normal grey or silver fish by the ancient Chinese. In several cases, the grey fish produced mutated fish that was yellow, orange or red. The yellowish orange (golden) fish were chosen to be further domesticated by the Chinese. Today goldfish is kept in aquariums at homes throughout the world. When goldfish is kept in a dark room for many days, it turns white.
