How many of us have won a goldfish at a fair, at a charity fishing, at a festival, we raised it in a glass bowl or a plastic tray with a lot of love, knowing nothing about him and his needs, but loving him with all my heart?

It has a robust, compressed but tapered body with an elongated shape as in the case of the Comet, or with an egg shape as in the Oranda. They all have good eyesight except Black Moors and Bubble Eyes who cannot see far, if you decide to have these 2 species in the aquarium, you must take special care as they may have difficulty feeding if there are other fish in the same tank. The caudal fin changes for each species, the evident lateral line helps in movements and in avoiding obstacles.

The dorsal fin of these fish also works as an alarm as regards health, if the fin is open, the fish is in excellent health, if instead, it keeps it closed it means that there are problems, the Veiltail species has dorsal fins of considerable size. The pectoral fins located near the gills are used by these fish to move back and forth, while the pelvic fins, placed between the anal and pelvic ones give stability, the caudal fins serve as a motor and the main source they use to give themselves the thrust, single finfish are faster than double finfish if you want to avoid unpleasant competitions for food intake, avoid introducing different finned fish in the same tank.

The Oranda, Lion’s Head or Ronchi, have two peculiarities, the head has fleshy growths or small benign tumors that resemble a cauliflower, the Chinese call them Wen, some have the entire tail fin, moreover, they do not have the dorsal fin.

The color varies from mono-colored to multi-colored tones, the most commercialized are reds, oranges, and whites, but there are infinite varieties. To determine the colors is above all the temperature of the water, below 18 ° C they remain of the color assumed at birth, that is on the olive-brown, while at temperatures above 20 ° C the colors range from red to orange, the goldfish seems a small miniature carp.

Even if it does not look like a very precious fish, labeled as a fish that is cheap, of few pretensions, and that never dies, it still needs care and attention like all other fish, aquarium, equipment, habitat, food, everything must still be adequate. . Classifying the different Carassius species is not easy but the Goldfish Society of America GFSA have used 3 simple identification criteria, or 3 categories:

  • Category 1 – all dorsal fin and single tailed fish
  • Category 2 – all dorsal finless fish with double tail
  • Category 3 – all double-tailed dorsal fin fish.

The tank to accommodate a Carassius must be at least 100/150 liters for a couple since it grows quickly in size, suffers from loneliness so it is advisable to breed them in pairs, the aquarium must be well oxygenated, with few plants, better if plastic and broad-leaved, anchored to supports or furnishings, sub-layer of coarse gravel, a good filtering system, furnishings but not too many, this is what you need, nothing else, to make them happy and live in health. The dimensions vary from 22 cm to 35 cm. If well-bred, goldfish can live up to 30 years.

History Of Carassius Auratus

The goldfish is the first fish raised by man, it has very ancient origins, we speak of the Jin Dynasty from 265 to 420 AD it was bred as a food carp, among these there was the Prussian Carp or the Carassius Gibello, the ancestor of Goldfish, from time to time among the carp were found variants of different colors, curious and captivating, from the classic gray-green color, they were red, orange, albino, given their bizarre colors they decided to breed them for domestic use in the various ornamental lakes of noble properties.

During the Tang Dynasty, from 618 to 907 AD, every noble and wealthy man had orange-colored fish in his ponds.

During the Song Dynasty around the year 1000 AD, the breeding of yellow fish was forbidden because this color was reserved for the emperor.

During the Ming Dynasty from 1368 to 1644, the breeding took a turn, the Carassius were raised in terracotta containers and the first genetic and physiognomic mutations of the fish developed, among these, the first heteromorphic goldfish or with the split tail fin and egg-shaped body.

In the seventeenth century, the breeding is no longer exclusive to the nobles and begins to be exported also to Japan, where many breeds are selected including the Jikin and the Tosakin, as previously mentioned they were raised in terracotta or ceramic containers, then viewed from an elevated position, for this purpose the Japanese put their efforts in the selection of fish with extravagant large fins, so that they could be observed from above. It has become an integral part of oriental culture and today particularly unusual-looking fish are selected. In 1608 they were imported to Europe, Portugal and from there in 1864 they were exported to the Americas.

From the Tang Dynasty after 1000 years, the Goldfish has colonized the whole world and inexorably entered the hearts of many aquarists, both newbies and experts in the sector.

Carassius Auratus Habitat

The Carassius Auratus is native to Asia, from Siberia to China, where for centuries it has been selectively bred as a domestic fish, lives in slow-flowing streams, ponds, lakes, and ponds, in temperate environments with relatively cold waters, survives several hours outside from the water, in the mud and even under the ice. In nature, in ponds, it can measure from 35 cm to 45 cm and weigh almost 2 kg in weight. It’s wild breeding in recent decades has made it available everywhere and bisfrattato, as a species.

Carassius Auratus Diet

Omnivorous species eats whatever is served but they prefer vegetables, food for redfish flakes, granular, live like insects, crustaceans, mollusks, worms, dry foods, salads, algae, and all kinds of vegetables, then remember to remove the residues from the tub to prevent them from rotting.


Oviparous species, it does not form a couple and feeds on their fry. During the reproductive period, the males develop small white dots, called tubercles nuzialisia on the head and on the caps and pectoral fins. They are very prolific. Reproduction occurs almost all year round, sometimes even several times a month, with temperatures around 15 ° C to 20 ° C.

Courtship begins when the males chase the female relentlessly, force her “into the corner” in the aquarium and begin to hit her with the mouth and head on the belly so that the eggs come out, it may happen that not a single male is courting her and this stresses the female exponentially, it is good to feed high protein food during this period to strengthen the female.

The eggs fall freely into the tank settling on the large-leaved plastic plants, after which take the plants and put them in a separate tray, unfortunately, if you do not transfer the eggs to an external nursery with mature water, to make them mature you can use algae or banana peels, the ideal would be a tank of about 50/60 liters, with the filter protected by a nylon sock to avoid sucking up the fry.

In a common tank, as soon as the fry are born, the parents will feed on them, for this reason normally the births that reach the total development are very rare, rare but not impossible.

After fertilization, the water must be changed by at least 10/15% every week, because the sperm of the males will numb the water and make it polluted. Once fertilized, 5/8 days pass to the hatching of the eggs and you will see the first fry of about 3-4 mm, which will look like many small tadpoles, will remain hidden among furnishings and plants, after 10 days they will begin to feed on their own and swim to ‘ inside of the tank. Feed the fry with infusoria of organic substances, after 2 weeks start feeding them with artemia in small doses several times a day.

After about a month the fry will have become minnows in all respects of about 1 cm and can be fed with freeze-dried artemia and high protein food, after about 4/5 months they will be large and robust enough to be placed in the common tank, in gradually, replacing the water in the tank with the water from the large tank every day until they are accustomed to the new biotope, so as to insert them into the large tank without causing trauma to the fish.
