A chart shared by a member of the Goldfish Forum detailing the lineage of goldfish based on the Japanese system. There are many names that are unfamiliar to the casual or even seasoned enthusiasts. Below is a grossary and description of the names that I managed to pick bits and pieces from everywhere:
1) Huna - Japanese term for the Wild Crucian Carp
2) Hibuna - Red/Golden Crucian Carp as a result of mutation. Also known as the Common Goldfish.
3) Wakin - Twin Tailed Hibuna
4) Ryukin - Popular Goldfish that originates from the Ryuku Islands
5) Watonai - Intermediate between Wakin & Ryukin
6) Demekin (Aka, Sanshoku, Kuro) - Telescope or Moor
7) Tyotengan - Celestial / Bubble Eye varieties
8) Shubunkin - Calico Comet with rounded caudal tailfin
9) Azumanishiki - Calico Oranda
10) Tetugyo - Comet
11) Tetuonaga - Similar to a fantail
12) Hanafusa - Oranda Lionhead with pom pom
13) Nankin - Ranchu without headgrowth
14) Edonishiki - Calico ranchu
15) Osaka ranchu - Ranchu w/o headgrowth, rounder and broader body, 3 lobe almost horizontal tail.
16) Maruko - Old variety of ranchu that is no longer bred. No headgrowth. Body similar to today's lionhead.
17) Syukin - Japanese lionhead with long ribbontail caudal finnage.
18) Kiransai - Old variety of goldfish. A cross between the Wakin & Lionhead
Possessing all the grace of a ballerina, the Tosakin is a relatively exotic breed of goldfish that originates from Japan. It’s overall shape and form resembles the Ryukin, from which it is descended; albeit the Tosakin was developed to be admired from a the top. If the Ranchu is known as the ‘King’ of Japanese goldfish, then the Tosakin is aptly known as the ‘Queen’.
The Tosakin has a spectacular tail shape and is truly the only goldfish breed with fuzed twintail lobes. When viewed from the top, the tail forms one continuous ‘skirt’ that rarely separates beyond the 1/4 point towards the peduncle. This gives the Tosakin an extremely graceful form and fluid like movements.
Apart from the tail, finnage is more or less similar to the Ryukin’s. The body however, does not display the characteristic hump as in the Ryukin. Coloration is varied but more commonly self coloured red and white, as these are judged to be the ideal ‘Japanese’ standard.
