Gold fish

Goldfish was one of the first fish species to be kept in ponds by
humans. It hails from a wild carp, probably the Crucian Carp, but has
been bred selectively for centuries in China. Goldfish is still a very
popular fish in aquariums as well as in ponds and can today be obtained
in a wide range of different variations. If you look further down this
page you will find articles about both commonly kept Goldfish types and
more unusual Goldfish variations.

All Goldfish variations belong to the same
species, Carassius auratus auratus. According to Chinese tradition the
different Goldfish variations are divided into four basic groups.

   1. Ce goldfish or Grass goldfish are goldfish without any “fancy“
features. The Common goldfish is very similar to the carp from which it
has been bred; the main distinguishing feature is the colour
modification. Unlike the wild carp, the Common goldfish can be obtained
in a wide range of colour variations, including white, black, lemon
yellow, orange and of course the golden colour.

   2. Wen goldfish are goldfish equipped with a dorsal fin and a fancy
tail. An example of a Wen goldfish is the Fantail goldfish that has a
dual-lobed tail that can reach a size of three inches.

   3. Dragon Eye goldfish have protruding eyes. As the names suggest,
the Bubble Eye goldfish and the Telescope Eye goldfish both belong to
this group.

   4. Egg goldfish is a goldfish that has no dorsal fin. One example of
Egg goldfish is the Japanese Ranchu goldfish. If a Bubble Eye goldfish
is without dorsal fin, it is considered a part of this group instead of
the Dragon Eye goldfish group.

Compared to many other fish species that have been bred and developed
in captivity, the Goldfish has a remarkably long history. Its ancestor
is believed to have been the Crucian Carp, a comparatively small carp
with a dark grey to olive-brown colouration. The Crucian Carp is native
to East Asia, and it was the Chinese that began to keep it in fish
