The Goldfish, (Carassius auratus auratus) is one of the two most popular pets in the world, with its only rival being the Budgerigar. 

Goldfish and a number of related species were the first fish recorded as being domesticated.  They came originally from China where they have been kept for over a thousand years.  The wild Goldfish was a bronzy colour, and was a very tough fish.  There are now well over 100 different varieties of Goldfish.  One of the first things done by selective breeders was to breed from the occasional gold coloured wild goldfish.

Much selective breeding has been done in many countries, notably Japan which had Goldfish brought from China in 1603. Goldfish were imported into Portugal in 1611 and spread to the rest of Europe.


Goldfish are bred in huge quantities in many countries.  Naturally the ones best suited to the conditions of any country will be one bred in that country rather than imported.


Comet Goldfish


The Comet Goldfish is of a similar shape to the wild Goldfish, Carassius auratus, but with a longer tail.  Comets can be of a wide range of colours although the most common is gold.



In the United States of America where this variety of Goldfish was developed, they are often referred to as "Comets Goldfish" or "Comet tailed Goldfish" In Australia they are normally called "Comet Goldfish".  They were developed in the 1880's, probably by Hugo Mulertt, from the common Goldfish.  The Comet is generally slimmer than the common Goldfish and has a longer and more deeply forked tail.  On some comets, the tail can be as long as the body, and can be up to 12 inches long.


The Comet is probably the best variety of Goldfish for ponds although the ones with extremely long tails may be more delicate.




The Shubunkin Goldfish is the same shape as a Comet Goldfish, but has many colours on a 'blue' background.  The colours may include black, red and white and the appearance is often mottled.  They should be a hardy fish and often are.  The ones that Betta Trading sells are from Boolarra Fish Farms and are well adapted to the conditions in Australia. They are suitable for either aquariums or ponds.


Some of the imported Shubunkins available from some wholesalers are not as hardy as they should be.




The Shubunkin was developed by  Kichigoro Akiyama in Japan in about 1890 from a complex cross involving a Calico Telescope Goldfish, a Common Goldfish and a Wakin with a single tail.  There is some doubt about the exact ancestors used. 

The name "Shubunkin" was given to this variety by Mr. Shinnosuke Matsubara of the Ministry of Agriculture, Forestry and Fisheries of Japan and was announced in 1892. It means something like a Goldfish with bright colours, including red and blue.


The Bristol Shubunkin was developed in Britain and has a heart shaped tail.
