Goldfish: Let’s Find Out All About The Most Classic Fish!


Goldfish information, races, characteristics, behavior, diseases, and useful advice on care, what they eat, and how to set up an aquarium.

Goldfish features

The first thing to know is that what we commonly call goldfish or goldfish or goldfish red actually has a specific scientific name, (or in Hindi गोल्डफिश का साइंटिफिक नाम क्या है) Carassius Auratus, a close relative of the carp, and is a freshwater fish belonging to the family of Cyprinidae which originally comes from China.

The goldfish has a well-proportioned and homogeneous body structure, the fins are proportionate, the mouth is small and without barbels, and can reach a maximum length between 22/25 cm.

This type of fish is quite resistant and, if treated with little but due care, it can survive even for fifteen years.

The goldfish do not like being alone in the aquarium so they have very sociable and can also be trained, of course, with very simple tasks.

Goldfish Breeds

The goldfish belong to a single race but, morphologically, are different from each other so we can distinguish them according to different varieties.

Let’s see together which are the varieties of goldfish most loved by Indians:

  • Common Goldfish: it is the one we all know and it is the most widespread on the market.
  • Comet Goldfish: its name derives from the fact that the tail fin is very developed and when it swims it seems to leave a trail similar to a comet in the water.
  • Pearlscale Goldfish : it is so called because its pearl-colored scales form a sort of crown on top of the head.
  • Trumpet: it has very long fins and an egg-shaped body.
  • Demekin: Also known as dragon’s eye, it has a very small, stocky body and telescopic eyes.
  • Oranda: This fish has a rounded body and is one of those often found in aquariums for enthusiasts.
  • Nymph: it is orange in color and is perfectly the same as the common goldfish.
  • Oriflamme: also known as veil tail fish, it is appreciated for its elegant fins.
  • Celestial: also known as the crybaby, this variety has protruding eyes that always face upwards.

Diseases and Feeding

First of all, it is good to know that goldfish (to be clear, the most common species, with soft and veiled fins, protruding eyes, and a rather stocky and short body …), are very sensitive to stress.

And there are many stressful situations for this fish, such as the sudden change in temperature.

When changing the water, pay close attention to the temperature which must remain as constant as possible to the previous one.

These fish suffer enough in the intestine, mainly because they are great eaters and tend to eat far beyond their needs and their subjective digestive capacity.

This overeating can lead to intestinal disorders that can also lead to rather serious complications.

We, therefore, advise you to scrupulously check the doses of food placed in the aquarium (maximum 2 or 3 times a day and in quantities that are not excessive, such that they can be eaten by the fish in about a minute), and to give our friends food. quality as granule feed or “live feed” Such as daphniamosquito, and brine shrimp.

We must never overlook the fact that goldfish suffer a lot from the presence of nitrites and nitrates in the water, substances that are produced by the animal’s own feces and that behave on its organism like a real poison.

Yes to large aquariums, able to guarantee each fish a quantity of water necessary to dispose of the waste it produces.

We remember that these little friends of ours are also subject to infectious diseases and cancer diseases.

How to set up an aquarium

Contrary to what we are used to seeing, the glass bowl is not good for our friend with fins, but a rectangular aquarium that has the capacity of at least 10 liters per goldfish is needed which must be covered with a plate during the night.

The water temperature must be between 18 and 23 degrees and for this species, you can use tap water, maybe you can use a product that eliminates the excess of metals and chlorine and it is necessary to always keep it clean.

The goldfish love the company of their own kind, so do not make them feel too alone, but buy at least two, but does not go very well with fish of other species: better to avoid, or risk conflict.

The aquarium can be safely furnished with many aquatic plants (oxygen production) as the goldfish is not a lover of vegetation and consequently does not eat it, on the contrary, it goes to store its eggs safely.

Do not forget the aquarium lighting which is essential.

How to distinguish male goldfish from females and breeding

As it should be, the male fish differs from the female for the size of both the body and the tail (the tail of the female is usually larger than that of the male) but to really understand the sex it is necessary to carefully observe them during the reproductive season.

The male fish reaches sexual maturity around the first year of age that is when it develops bridal tubercles close to the fins while the female fish reaches sexual maturity when the belly fills with eggs.

The goldfish are very prolific and their reproduction takes place, usually, in the spring or summer and that is when the water temperature exceeds, stably, the 16 ° / 17 °.
