OK Ryukins
Ryukin body should be egg shaped.The depth of body should be about 3/4 the length and then another 1/3 of that depth in height of dorsal. This has all paired fins. The paired Caudal fins should be at least about equal to the length of the body. The two parts should be split almost to the peduncle and the tips should be round.The pelvic, and anal fins should be equal in length and size. Long and flowing are better. Pectorals should have similar shape and almost as big. All best to match in color.
The Ryukin is special from other goldfish in the hump on its shoulder between head and dorsal. More pronounced is better. This hump is generally more pronounced on Ryukin of red, white or both. Many other colors like Red/Black, Tricolor, and calico tend to have smaller humps due to genetics. I have found all reds or red/whites compete the best. The tendency now is to see more veiltail and the longer finnage is preferred for show points, even though some of the new short tail varieties have a nice look.
These are also judged on deportment, so the Caudal needs to be carried well when swimming.
Color should be sharp and deep and symetrical.
When using point system you have
20%Body
20%Color
20% Finnage
20% Hump, and the way the tail is carried
20% Deportment and conditioning
This last one is basically how it shows itself off to the Judges. Is it alert with fins out or is finnage down and lying on bottom? This is what I mentioned on another thread of how important it is to have a tank mate at shows and have the right type to show off koi
The conditioning has to do with the fourth 20% as well as it will carry over to finnage carry.
This is where proteins in diet are important to muscle deportment.
