![]() ![]() Western goldfish societies tend to use glass tanks for judging, but a number of societies based on Japanese methods are now operational and follow the traditional way the ranchu are bred, kept, and judged. Although the overall shape of the ranchu is taken into account it is the top view that is the most important. True Japanese ranchu are judged from above in shallow bowls but not glass tanks. The attachment of the tail to the caudal peduncle is also evaluated. Judges view the fish from the side and the top, taking note of its comportment and conformation to physical standards, motion, and movements. Most goldfish shows and competitions judge ranchus in an aquarium setting. Both comb shapes are acceptable in Ranchu exhibitions and competitions. The mature or the round style is shorter and is similar to a round coin viewed from the side, but still not as round as any circular coin. The negate or long style is long with rounded corners and is similar to the koban coin. Side-view ranchu (SVR) Ī ranchu's back (seen from the side) is comparable to a traditional Japanese comb, which comes in two shapes. When swimming, their appearance should resemble a worm moving in water, which gives the ranchu its name (in Chinese, "luan chong" means "egg shape worm"). The TVR should have a rectangle shape, a short tail, and big wen on the head. Therefore, the top view ranchu is considered better aesthetically in Japan and China. For this reason, generations of people selected goldfish with big bellies, big wens, and dragon eyes genes. In ancient China, goldfish were kept in large jars made of pottery or porcelain, so the only way one could see the fish was from the top.

However, traditional Japanese culture, aesthetics, and concepts regard these attributes of both ranchus and sumo wrestlers as an imposing and solid figure composed of massive circles and squares, which are abstract representations of balance, proportion, dignity, graceful movement and power. Ranchus are often compared to sumo wrestlers, as the ranchu is a rounded fish with a head-growth (known as a "bramble-head" ). Japanese aesthetic standards for ranchus are more exacting. Japanese, Thai, American, and British ranchu breeders, as well as many goldfish societies, adhere to two strict viewing classifications, namely the top-view ranchu comportment and the side-view selection criteria. Top-View Ranchu from the USA Classification, deportment and conformation Ranchus are well-adapted to fluctuations in pH levels and water quality. Ranchus with pale-yellow bodies and bright red heads are rare. Scalation may either be metallic, nacreous (calico) or matte. Ranchus may come in orange, red, white, red-and-white, blue, black, black-and-white, black-and-red, natural, and chocolate coloration. Mature ranchus can reach between 6 and 8 inches (15 to 20 centimeters) in length. Fry possessing broad foreheads and square noses generally produce better head growths. The head growths of ranchu fry may take at least a year to develop. The head growth should seem to begin from the bottom of the gill cover and move upward. The gill cover should extend towards the tail. Sufficient space between the eyes, and also from the eyes to the front of the head must be preserved. Ranchus' most prominent feature are their heads. Ranchus have arched backs and much shorter tails, which are tucked in at a 45-degree angle. Ĭompared to lionheads, ranchus have a particularly down-turned tail and tail fin. The tail lobes are rounded, and all other fins are paired. ![]() ![]() The ranchu's tail meets the caudal peduncle at a 45-degree angle, giving the fish a unique swimming motion. A properly formed caudal peduncle avoids swimming motion impairments. The area of the caudal peduncle should curve sharply downwards to meet the tail. The back should be rounded, not flat like a lion head. Breeding standards require that the back should not have any vestiges of the dorsal fin on it. Ranchus have egg-shaped bodies and deep bellies – between 5/8 to 3/4 the length of the fish. ![]()
