Over the course of several centuries, goldfish have been developed through selective breeding to have distinct species-specific characteristics. More than 300 goldfish breeds have been created as a result of years of selecting individuals with distinctive species features and refining breed standards. The development operation does not cease or lose relevance, regardless of how long it takes.
The present species may be traced back to four basic types: torpedoes, ranches, demekin, and riukin.
The different forms of gold are distinguished by their form:
- bodies – an egg, a drop, a torpedo, a wild look;
- fins – single, double caudal, no dorsal;
- eye – sphere, hemisphere, cylinder.
Breeders in Asia are attempting to develop breeds with eyes that are positioned close to horizontal. This is due to the fact that, unlike European nations, Asian countries do not view fish from a perspective rather than directly above them.
The Shubunkin is one of the most attractive in color goldfish. The individual belongs to the carp family. The coloration of this fish, consisting of multicolored specks scattered chaotically along the body under the transparent mosaic scales, is unique.
The demand for common gold is modest, with only a few species available. The fish differs from wild goldfish in that it is more golden-orange in hue and has black splotches on it. The paired pelvic and pectoral fins are tiny. The scales have a metallic gleam to them.
The species has the same basic shape as preceding generations. The form of the fins, however, is similar to that of its ancestors. A forked tail covers a quarter of the body length and is bright yellow or orange markings on a white body, whereas Japanese breeders develop the breed, such as koi carp, for ornamental ponds.
A stunning lengthy tail is a characteristic feature of small torpedo-shaped fish that grow up to 20 cm in length. The origin of the breed has yet to be determined. According to some sources, this breed was developed in the United States, while others claim it was created in Japan. Not only for its long tail, which is many times longer.
Telescope goldfish are small, oval in shape, and have long fins. The black telescope is uncommon in home aquariums. The fish’s prominent feature is the largest among golden variations, protruding cylindrical eyes that look to the sides or up. As a result of them, the breed was given additional names such as dragon eye
When viewed from above, the Demekin with a tail reveals spread “butterfly wings.” The eyes of breed animals vary in shape, size, and gaze direction. Golds of this species delight their owners with a variety of hues. “Panda” are butterflies with black and white markings that resemble bamboo bears.
The fish has a tiny body. It differs from other breeds in that its head extensions resemble a lion’s mane. The operculum and vertex get large enough to close the eyes and mouth, thanks to seals on the crown and nape of the neck. The sharp angle is formed by the upper ray of the forked tail with respect.
Growths in Japanese goldfish of this sort begin appearing after two years and last three months in the remainder. The majority of individuals have white bodies and red gill covers, or white spots on a red body. White-black, light red, golden variants are particularly prized among aquarium owners.
The ranch goldfish has a lion-shaped body, no back fin, and a prominent growth on its head with a raspberry berry-like structure. A steep spine curvature, a partially divided double caudal.
Painted goldfish are most popular among Japanese fishkeepers, followed by white and red, orange, black, and mother-of-pearl fish.
On a tiny ovoid body of gold, convex scaly plates, which look like pearls, stand out. Chinese fish grow up to 15 centimeters in length. Golden, white, and orange are the most popular scales colors.
A 50-liter tank with all of the necessary components, including soil from coarse fractions that grows rapidly, is ideal for preserving this species.
The unusual form of the veil fins draws attention to the appearance of gold ones. The long, bushy tail is considerably longer than the body. The head, which has huge sight organs, smoothly transforms into a spherical physique.
Bubble Eye (Water Eyes)
The eyes are golden and have a peculiar appearance, with large water bubbles the size of a quarter of the body’s length beneath them. The dorsal fin is missing from this ovoid form. Bubbles are the most fragile area in black, calico, pink, or goldfish because they are white.
The species’ slow, mannered representatives are decked in a long forked tail. An erect, robust dorsal fin can be seen on the body, while huge eyes stand out on a large head. Varied and monochromatic colors abound.
The gold-colored dragon is named after a Chinese city and comes from China. The golden dragon’s unique tail, which resembles an inverted “V” and is red and white striped, has enticed breeders. It’s difficult to maintain species specifics while breeding Nanking fish because there’s a high danger of crossbreeding.
A cap-shaped growth on the head, which is different in hue from the scales, is the most notable feature of the golden breed. By two years old, a leathery formation appears on Oranda’s tail. Oranda’s length and volume of fins make it resemble a veil tail. The brighter the growth on a modest creature’s head
The view’s main feature is a beautiful tail in the form of an open fan, which is best seen from above. The golden one’s massive body and voluminous tail fin define its slowness and clumsiness. Because even the tiniest current makes it difficult for fish to swim
