Are Koi really a goldfish?

Answers:
Koi are NOT goldfish, and yes, the common carp is the forerunner of the present day Koi and the present day goldfish, so they are from the same family, but not the same.

The ancestor of the goldfish - a small, plain carp - came from south/central China. Nearly 2000 years ago, the Chinese started to selectively breed these fish, at first in small ponds and later in even smaller containers such as large clay pans, to develop certain features, such as colour, body shape, etc. Today, millions of goldfish are bred all over the world each year.

Koi - the style of breeding and ornamentation has become very similar to that of goldfish, probably through the efforts of Japanese breeders to emulate goldfish, but they are not goldfish.
