Goshiki's changes colour depending on the temperature of the water.
Goshiki means five colours.
I don't like the normal Wagoi version when small, but after two to three years, they develop into stunning fish.
The Doitsu version is quite rare, and I seldom see one in South Africa.
It is pronounced Gosh-ki and not Gosh-Shi-Ki
Goshiki's are a cross between Kohaku and Asagi, where the Asagi is dominant (male)
You get two types of Goshiki apart from the Sanke Goshiki and Showa Goshiki.
1 Kuro Goshiki (Old style and becomes very black) The last Goshiki posted above is a Kuro Goshiki. The contrast between the almost black and the red is often very striking. They develop with time as the asagi pattern develops.
2 Modern or new style Goshiki. Often very much the same as Goromo. They are much lighter and are often overlooked as a lessor quality Kohaku, as the grey underneath the white gives the impression of poor shiroji.
Sometimes, they initially look exactly like a Kohaku, and the Asagi pattern takes time to develop.
The five colours of Goshiki are black, red, white, blue and grey or silver.
When choosing a small Goshiki, you must follow the Kohaku rules, look for a good Kohaku pattern.
The most beautiful one that I have seen is the one that won the Special variety prize at the Cape Town 2008 show:
