Celestial Eye Goldfish
The Celestial Eye Goldfish is a double-tailed breed of fancy goldfish with a breed-defined pair of binocular eyes that are turned upward, the pupils looking up at the sky.
When the fry hatch, the eyes of young celestials are normal, but gradually spread sideways, as in the telescope eye goldfish, but unlike binoculars, which have their eyes facing out on each side, the celestial eye’s eyes strictly turned upwards.
Within a six-month period of development, this process is entirely governed by genetics, although early sources perpetuated the myth that fish were bred and kept in mud jars with narrow necks and limited sources of light. His eyes turned upwards in search.
Origin of Celestial Eye Goldfish
Celestials first appeared in the 18th century as a direct mutation of the telescope goldfish. Competing traditions claim where it happened first, Korea or China. The first document of celestial existence appears on a 1772 Chinese scroll, where a goldfish lacks a dorsal fin and has bulging eyes.
The celestials did not arrive in Japan until 1903 when thirty specimens arrived from China and became the foundation stock for Japanese breeders.
Japan soon became the leading producer of celestial objects for export. It remained that way until World War II broke out.
Celestials arrived in the United States from Japan in the first decade of the twentieth century, and in 1917 William T. Inns Key Goldfish Varieties and Tropical Aquarium Fish were included in the first edition.
American radicals successfully reared the fish and, in turn, the foundation stock exported to Great Britain. After World War II, and since then, most Celestials exported from Asia are of Chinese origin. A postage stamp issued by the People’s Republic of China in 1960 depicts a celestial goldfish.
Celestial Eye Goldfish Description
The celestial is a goldfish with an elongated egg-shaped body similar to that of a bubble eye. Like the bubble eye, celestials do not have a dorsal fin. Their paired feathers are of the fantail or ryukin type.
The tail can be half as long, to the body. They are commonly seen with metallic scales in shades of orange (called ‘red’ by fanciers), white, or red and white. Nacreous scaled celestials are known, however they are rarely encountered.

Despite their limited vision and lack of a dorsal fin, they are active and agile swimmers. They require some special attention, because in addition to being easily damaged by upward-oriented eyes (and, consequently, those with limited vision), they are sensitive to cold water temperatures.
They are unable to compete with the more vigorous goldfish for food. Pointed ornaments and objects are inappropriate in the aquarium. They are best kept with other limited-sighted breeds (such as the Bubble Eye) or in a tank of their own.
Celestial Eye Goldfish Variants
The original celestial breed, described above, is still bred and exported by Chinese and Japanese breeders and is commercially available to fans, although they are not as commonly stocked by aquarium shops and dealers as some other goldfish varieties. go.
This 240+ year old form is described in the American Standard adopted by the American Goldfish Association and the Goldfish Society of America.
British fans love their Celestials for their dark bodies and short plumage, and have been selectively bred to have these features as required by the British Standard.
In recent decades, the Chinese crossed celestials with several other breeds, most commonly Lionheads, Ranchus and pompoms, producing much larger fish with short ranchu-like fins and very deep, blocky bodies, often nasal ‘bouquets’ and Top growth with rudimentary.
Some of these crosses are less animated swimmers, particularly those that have a short, sharp downturn, ranch-like caudal peduncle with flared and short caudal fins, traits that are otherwise unattainable for the breed.
Such fish can be quite sedentary, spending most of their time on or near the bottom of the aquarium; However, a much wider color range can be found among these hybrids, with metallic specimens appearing in chocolate, black and various bi-colors in addition to the standard metallic colors, and seen in bi-color, tri-color and calico and nacreous fish to go.
These hybrids are not usually commercially available outside Asia, but can be obtained through specialist dealers and importers. DEME – Ranchu is similar to celestial in composition save for its binocular eyes which do not turn upwards.
In any celestial spawning, many fry will be found maturing with farsighted eyes that never turn upwards. These fish are similar to DEME-Ranchu.
Toadhead or hama-tou in Japanese, although they are not dissimilar, each resembles the celestial in having eyes formed upwards supporting a small bubble-like growth sac beneath it. It is believed to be the ancestor of both the celestial eye and the bubble eye goldfish.
