Goldfish are breeds of crucian carp!
Sometimes the variety of fish in aquariums is astounding. Furthermore, because each species of fish has subspecies, the world of aquariums grows enormously. Even seasoned aquarium enthusiasts occasionally struggle to identify the type of fish they are looking at. With any luck, the list of goldfish "species" that follow will enable you to identify the inhabitants of your aquarium.
The fact that goldfish were first bred in ponds and garden ponds on the estates of affluent and noble people in China over 1,500 years ago is an interesting fact. The first goldfish were brought to Russia in the mid-1800s. Goldfish today come in a variety of breeds, all descended from the common silver crucian carp.
Silver crucian carp has proven to be an excellent subject for breeding work. As a result of long-term selection in China, Korea and Japan, several hundred breeds of this ornamental fish have been bred. In a domesticated state, they have lost the mobility characteristic of their wild ancestor, the body of most breeds has become shorter and wider. The length and shape of the fins have changed. Some breeds lack dorsal fins, while others have changed the size and position of the eyes. There are fish with various growths on the head, with transparent scales. The variety of colors is especially great. There are several color variations: red, silver, black and others. The most diverse combinations and changes of these features give an extraordinary variety of forms.
Considering the aforementioned, it would be accurate to state that there are no "species of goldfish"; instead, they are all breeds and stable mutations within a single species (much like dogs). We respectfully ask that everyone who reads this material can read it and tell others about it. Views, rocks, and hybrids differ greatly from one another. A species is one unique individual. Breeds are variations within a species that have been deliberately and selectively fixed. Subspecies are simply natural mutations that occur within a species. Mutations resulting from crossing different species or morphs of species are known as hybrids (e.g., a swordsman with a pedicilia).
There is a version of the legend that claims all crucian carp genetic abnormalities—such as head growths, double tails, dorsal fin absence, etc.—are hereditary.p.) were originally corrected by accident (by selection), but for reasons related to religion. In the seventh and eighth centuries, almost all goldfish breeders were Buddhists. Buddhism forbids the killing of animals. As a result, instead of being destroyed, all of the freaks resulting from inbreeding were placed in unique "mercy ponds," where the freaks were breeding and eventually fixed genetically by themselves.
"Types": Breeds of goldfish
Celestial eye or astronomer
The stargazer’s body is ovoid and round. The fish is unique in that its telescopic eyes are angled slightly upward and forward. These fish are incredibly beautiful, even though they are seen as a departure from the ideal. The stargazer has an orange-gold hue. The fish can grow up to 15 centimeters in length.
Eyes of water

Wakin Ryukin
But the world of goldfish is not limited to these variations. There are no limits to the fervor of Chinese and Japanese breeders! Breeds of "rare species of goldfish" are shown below.
Butterfly – goldfish

In the 1980s, golden butterflies first showed up on the aquarium scene. Although it was initially bred in China, Japanese breeders currently provide the majority of the supply. It shares many characteristics with Telescope, such as protruding on the sides of the head, and is the outcome of constant selection.

The caudal fin’s structure is the primary characteristic of butterfly goldfish. From above, its form resembles the wings of a butterfly. It tapers towards the end, rounding off after widening at the base. The coloring varies, and each group of colors has a name of its own: "Panda Butterfly" features black and white hues, while "Little Panda Butterfly" features a body pattern with specks of red and black.
Similar to caring for other goldfish, the maintenance is fairly straightforward. But it’s important to take into account the existence of two characteristics: a big tail and protruding eyes. Sharp edges on ornamental items or hostile fish in aquariums can harm them. The aquarium needs to reduce these possible hazards as much as possible. Slowness could be an additional issue. More mobile neighbors will outcompete the fish in the race for food. suggested preservation of species.
Aquarium enthusiasts favor goldfish because of their vivid colors and wide range of varieties. Everything you need to know about keeping goldfish is covered in this article, from feeding advice and common health problems to basic care requirements and the perfect tank setup. Having a thorough understanding of these fundamentals will help ensure that your goldfish flourish and add happiness to your aquatic setup, regardless of your level of experience.
Dzhikin – goldfish
Picture of Dzhikin goldfish
The rarest type of goldfish is called jikin. Due to its inclusion on the Aichi Prefecture’s (Japan) list of protected species, its distribution has been restricted since 1958, making it nearly impossible to find in amateur aquaristics. The species’ history started in the 17th century when Ryukin, a side branch of selection, was bred from regular goldfish. Jikin was developed for hundreds of years in what is now Nagoya Prefecture.

There are similarities between this selection form and Ryukin because of their shared origin. The body is rounded, with a big belly and a short stature. There are two upper parts and a lower part that make up the caudal fin. The fish’s tail resembles the outline of the letter "X" when viewed from behind. Jikin is occasionally referred to as "Peacock Tail" in Europe and America due to this characteristic.

The main feature of the Jikin is the color of the body. On the white body there are bright orange inclusions, located in strictly defined places: mouth, gill covers, ventral, dorsal and anal fin, area near the anal fin, tail. This coloring is considered standard, but is almost never found, so it is achieved artificially. Breeders use several methods: dye injections where there is not enough color, and pigment removal where it is excessive. It is worth noting that in Western countries such methods are condemned and fall under the local laws "On the protection of animals", since these manipulations not only entail stress, but also directly affect the health and life expectancy of the animal.
Nanjing – goldfish

Around 1750, in the Izumo area of what is now Shimane Prefecture, Japan, Nanjing was bred. The name is Chinese in origin, despite its origin. Some people believe that Nanjing, the port city and former capital of China, is where the fish got its name. At that time, the word "Nanjing" was used to refer to all goods delivered from this port. Among the goods were the goldfish, which are the source of this variety.

The Shimane Prefecture’s 1982 registration of nankin as a protected species severely restricted its export. Outside of Japan, it is rarely seen for sale.
The species is distinguished by a large body with a rounded, egg-shaped abdomen. The dorsal fin is absent. A rather short tail that is split in half resembles an upside-down "V." Red and white are combined to create the coloring.

Breeding Nankin presents challenges. Care must be taken when selecting a mate, or else there is a good chance of producing hybrid offspring that rapidly lose their distinctive characteristics.
Pompon: goldfish

It’s unclear exactly where these goldfish originally appeared in the tale. Nonetheless, only China and Japan are regarded as the ancestors. Pompon is distinguished by significantly enlarged nasal valves, which are nearly undetectable in their normal state. They resemble pompons, which are growths of different sizes and shapes that grow on the nose.

It is important to remember that a pompom is a characteristic that can be seen in different kinds of goldfish rather than a stand-alone variety. It was suggested in 1987 to split fish with comparable features into two sizable groups in order to classify. The Japanese pompom started to be referred to as orandas and its breeding forms (red cap, butterflies, and so forth). Water eyes, starship, and other breeding forms of I can were ascribed to Chinese pompons.

Chinese divorces currently deliver for both groups. However, a very particular appearance—we might even say ugliness—caused a lackluster demand and, consequently, a narrow proposal. Despite having the same traits as its relatives—endurance, unpretentiousness, ease of maintenance, and good compatibility with other species—the fish is rarely found for sale.
Not only are goldfish a popular choice for aquarium enthusiasts, but they also represent beauty and good fortune. These fish are a flexible addition to any tank because they are available in a variety of colors, shapes, and sizes. Your aquarium will become a dynamic and captivating focal point thanks to their brilliant colors and elegant movements.

Knowing what they require makes it more likely that they will prosper and lead long, healthy lives. A varied diet, proper filtration, and routine water changes are essential for maintaining your goldfish’s happiness and well-being.
Goldfish provide an opportunity to learn and develop, regardless of your level of experience with aquarium keeping. Taking care of them can be a fulfilling experience that teaches patience and detail-orientedness. Goldfish can become a treasured addition to your aquatic environment with the correct setup and dedication.
