What fish get along with gold in an aquarium?

The aquarium goldfish is peaceful, but compatibility with the rest of the inhabitants deserves special attention. Her health and life expectancy depend on this. Goldfish in an aquarium does not combine well with other individuals. it becomes either a predator or a prey, and even their relatives break off their fins in veil-tails. Danio, labeo, koi carp coexist with golden inhabitants without any problems. But it is believed that when populating such fish, a species aquarium with only golden varieties will be the best way out. This makes them feel calmer.

Taking care of your goldfish in the aquarium

Aquarium carp need simple maintenance, as long as it is regular. Mandatory measures for the maintenance of the reservoir:

  • weekly water change;
  • systematic washing of filters;
  • soil siphon. every two weeks;
  • cleaning glass from algae;
  • thinning and pruning of plants.

The water change is carried out at the level of 30%, an increase in this volume will lead to a violation of the biological balance and turbidity, the appearance of harmful unicellular organisms. The goldfish at home loves to dig in the soil, if it is dirty, then the environment also becomes not very clean. The bottom siphon should be carried out regularly. For the same reason, the filters are often clogged and need to be cleaned. The contamination of the device can be judged by the decrease in its performance.

Aquarium volume for goldfish

In nature, carp lived in ponds and were not used to confined spaces. In addition, due to their gluttony and the characteristics of the digestive system, they carry a large biological load on the home reservoir. When asked what should be an aquarium for a goldfish in terms of volume, experienced breeders advise using 50 liters of water for one individual and 100 liters for two. In this case, the inhabitants will be free to move, and the biological balance will not be lost in the environment.

The well-known goldfish often appears first in the aquarium. It belongs to the carp family and looks very impressive. Her ancestors were pond specimens. It is believed that goldfish appeared about one hundred and fifty thousand years ago and bred them in China. such individuals do not cause difficulties if certain conditions are met.

Breeding goldfish in an aquarium

Carp are bred in containers with a volume of 25 to 30 liters with a water level of no more than 20 cm. The vessel is filled with sandy soil, fine-grained plants and water, settled and kept in direct sunlight for several hours. In the spawning grounds, it is necessary to organize bright lighting and powerful aeration. A plastic net is pulled at a distance of 1-2 cm from the bottom.

It is interesting to observe how goldfish reproduce in an aquarium. For guaranteed spawning, take one female and two or three males. Two weeks before that, they are kept separately. Males begin to drive the female through the spawning grounds at high speed, which contributes to the distribution of eggs throughout the vessel. The mark lasts 2-5 hours. Upon completion, the parents are immediately removed. The incubation period lasts 3-4 days, at this time it is necessary to remove the whitened eggs. The emerging fry immediately begin to swim. Saturate them with rotifers and ciliates.

Diseases of goldfish in the aquarium

The indicators of the health of the inhabitants are their mobility, shine of scales, appetite, dorsal fin (should not be lowered). In case of suspicious behavior of an aquarium goldfish, it must be deposited in a separate vessel, observed and treated. The most common diseases are:

  • clouding of scales. scabies: then the fish is kept in a salty solution;
  • corduroy disease (velvet plaque): treated with becyllin-5;
  • fish pox. multi-colored tumors occupy the skin, they spoil the beauty of the individual, do not respond to treatment, but are not dangerous;
  • when overfeeding fish, a weak solution of potassium permanganate is added to the water in the isolator to wash the stomach, residents should not eat for 4-5 days.

Water temperature for goldfish in an aquarium

Aquarium goldfish are considered cold-blooded, they can easily tolerate a drop in temperature, but sharp fluctuations in it are unacceptable. Residents become especially playful in an environment of 22-24 ° C. Decorative individuals are more thermophilic. For goldfish in water with a temperature of 17-25 ° C, it is suitable for long-bodied species and 21-28 ° C for short ones. The hardness of the medium must be at least 8 °.

Goldfish. description

A brief description of a goldfish in an aquarium includes different body colors. Main color. red-gold, but other shades also come across: yellow, white, pale pink, black-blue and dark bronze. Its abdomen is lighter than the back. Individuals have a short body length, compressed on the sides, the shape is oval, round, elongated depending on the species.

According to the configuration of fins (single caudal, paired lateral and abdominal fins), the specimen is similar to crucian carp. They are short, rounded, depending on the type, they can have an elongated shape. There are also varieties with greatly enlarged veil-tailed or ribbon-like fins, which hang down beautifully like trains. The eyes of most individuals are of normal size, and telescopes are endowed with a strongly convex apple shape. In domestic reservoirs, the size of the golden inhabitant does not exceed 15 cm.

Breeding goldfish in an aquarium


In a telescope fish, the shape of the body is oval, identical with other representatives of the veil-tailed. Body symmetry is short and wide. The head is large with bulging eyes, fins are lush.

Modern breeders sell telescope fish in different colors and shapes. with short or long fins, red and white colors, and, of course, black. Black telescopes change the color of their scales with age.

Telescopes range in size from an average of 15 to 20 cm within the aquarium. They live in captivity for a long time, about 15 years. Fish that live in artificial ponds can live up to 20 years.

There is nothing difficult in keeping a comet fish. It is enough to comply with the basic conditions recommended for this species, and carefully monitor the condition of the pet. All this is also relevant for the maintenance of the black comet fish.

  • A sufficiently large aquarium should be selected for this species. First, the fish will grow up to 18 cm in length. And secondly, this type is often kept in small flocks. In addition, the character of the pet is quite active and agile. Minimum aquarium volume 100 l.
  • The ideal temperature is considered to be in the range of 20-23 ° C (while they can live at 15 ° C), pH 5-8.00. It is important to remember that all conditions of detention directly affect the appearance of the fish, so even unpretentious species should be kept only at the recommended water parameters.
  • Be sure to install a powerful filter. The fact is that the comet aquarium fish is very voracious, so it will quickly pollute the aquarium. Keep an eye on the accumulation of sludge at the bottom.
  • Of the plants, it is better to give preference to species with large leaves and a very powerful root system.
  • For the maintenance of the comet goldfish, it is important to take care of good quality lighting. This type of fish is distinguished by a bright golden color, which will be visible in good lighting conditions.
  • Any live food is suitable for feeding. You can also offer dry, combination or plant foods. Always monitor your portions carefully, do not overfeed.

Male behavior during spawning may resemble an aggressive attack. However, in this way, he only tries to provoke and accelerate the process of laying eggs by the female.

You need to feed the fry every three hours. If you see that small fish are often near the surface of the water, then do not rush to worry. Thus, they are just trying to get enough oxygen.

The fish are ready for reproduction from the age of two. Around March-April, you will notice the characteristic behavior of the males. They constantly chase females and at the same time stay as close to the ovipositor as possible.

If you raise the temperature in the aquarium by a couple of degrees, then it will go faster. For two weeks we separate the male and the female and feed them as satisfying and varied as possible, and before spawning we go on a hunger strike. The spawn should be about 100 liters. pour soft, settled water there.

When breeding comet fish, be sure to lay a protective mesh for caviar at the bottom. The period of development of eggs is four days, and after five days fry begin to emerge. The fry should be fed with live dust. With decent care, the young will grow up very soon and it will be possible to switch to rotifer or brine shrimp. Goldfish are suitable as a neighbor, it is better not to add small species.

Reproduction and breeding of goldfish

Reproduction and breeding of goldfish

Goldfish are one of the most ancient aquarium fish. Their history begins in the first century AD and Ancient China. Even then, the emperors of the east and Buddhist monks began to keep, breed and select goldfish.

Actually, therefore, there are currently a great many aquarium goldfish, and their cost can range from 2 to several thousand dollars.

So if you want to feel like a true goldfish breeder, emperor or Buddhist monk, then this article is for you.!
Breeding or breeding goldfish is not difficult at all.

However, goldfish are not guppies and in order to get offspring, you still need to work hard and be patient. In addition, you need to have a sufficient number of aquariums or reservoirs.
You can’t get off with one aquarium!

Goldfish reproduce on their own, without any hormonal injection or overly specific conditions. Actual, good and correct feeding is the criterion and incentive for the spawning of the broodstock. All types of goldfish can spawn in small aquariums from 30 liters. However, the best results can be achieved in larger aquariums or in ponds.

Spawning of goldfish can occur at 16 degrees Celsius, however it is better to keep the temperature of the aquarium water at 22-24 degrees Celsius. After replanting the producers, the temperature is increased by 2 degrees. The water level in the spawning pond should be 20-25 centimeters, the water should often be changed to fresh water and aerated.

Unlike many other spawning aquariums, a goldfish spawning tank should be well lit throughout the day. If it is a pond, then the sunlight should be diffused, and the pond should be equipped with shelters in the form of floating plants.

Producers are planted in a spawning aquarium in a ratio of 1 female to 2-3 males, they are abundantly fed with live food (bloodworms, earthworms, daphnia, etc.). At the same time, they try to select manufacturers based on their size. Especially females. the larger they are, the more eggs they spawn. And vice versa. small females lay fewer eggs. The aquarium is equipped with vegetation (hornwort, Riccia, duckweed, pinwort, etc.), and the bottom of the aquarium is not covered with anything. on a clean bottom the eggs are better preserved and do not die, but some aquarists install a separate net. Sexual maturity in fish occurs by the year of life. In this case, males have white tubercles on the gills and the so-called “saw” on the anterior paired fins, and females grow fat with eggs, their body is bent. For more details see: HOW TO DETERMINE THE GOLDEN FISH GENDER.

A female matured for reproduction secretes a special substance that has a characteristic odor and is especially strongly concentrated in the genitals. Actually, this smell attracts males and is a signal of the female’s readiness for reproduction. Under the influence of this secretion, males begin to swim after females.

In the conditions of the pond, it is recommended to carry out spawning manipulations in March. April, with the expectation that spawning will begin in May. June. It is believed that this is the most favorable time for the successful maturation of caviar. In addition, at this time it is easier to provide the eggs and fry with the necessary comfort.

If the courtship of males began earlier than March. April and it is necessary to delay spawning, the producers are seated, and the water temperature is also lowered until the required period (period).

The peak of reproduction of goldfish is accompanied by violent courtship of males. they chase the female throughout the reservoir, and on the day of spawning, these courtship looks like outright pursuit.

Spawning itself begins with the first rays of the sun and lasts six hours. Gold can spawn every month until October. During one spawning, a female can spawn up to 3000 eggs. At home, spawning of goldfish can sometimes occur continuously. all year round. However, this leads to exhaustion of producers and in this case they should be given rest, seating them in different aquariums.

Eggs are washed out gradually. the female chased by the males touches the vegetation or the walls of the aquarium and releases 10-30 eggs, which the males immediately fertilize. watering caviar with seed.

Then, the sticky caviar falls to the bottom or sticks to the plants.

Eggs on the first day have a slightly orange color and are slightly flattened, the diameter of the eggs is up to 1.5 millimeters. On the third day, the eggs are straightened and discolored, and therefore, they are difficult to detect.

Immediately after spawning, producers are removed from the spawning aquarium, otherwise the offspring will be eaten.

The water level in the spawning grounds with caviar is reduced to 10-15 centimeters, protected from overheating and excessive lighting. The aquarium is heavily aerated.

The appearance of fry from eggs depends on the temperature of the water. At a water temperature of 22-24 degrees Celsius, the incubation period is 4-5 days, but at a temperature of 14 degrees Celsius it can reach 7-8 days.

How to Breed Goldfish (Natural Way)

On the second day after the juveniles appear in the aquarium, it is recommended to launch snails (for example, coils) so that they eat dead and unfertilized eggs. You can carefully assemble it yourself, but it’s more difficult. It is very important not to kill the young. At the same time, leaving dead eggs is fraught. live larvae do not tolerate “dirt” and can get sick.

In the early days, young goldfish are weak and harmless, in fact, they look like a reed with eyes and a yolk bladder in the middle (the yolk bladder is necessary to obtain nutrients in the first days of life). The fry move in jerks and can stick to the stop.

After about 2-3 days, they begin to swim carelessly throughout the reservoir, and from that moment the fry must be fed with starting food: live dust, the smallest algae, and other food ground into dust. Larger feed can be fed after 2 weeks. At the age of one month, juveniles are able to take small bloodworms. Egg yolk, finely grated in water, as well as soaked oatmeal, grated into dust, are also used as a starter feed. The fry are fed abundantly, but in portions. little by little, but often.

We recommend the following food for juvenile goldfish. TetraMin Baby. a quality sifted blend of highly nutritious and functional ingredients to support healthy growth in the early stages of fish life.

After two weeks, the fry are placed in 30 liter aquariums at the rate of 250 fry per aquarium. Aquariums are purged or frequently changed. Without blowing-aeration, it is recommended to plant 120 fry per aquarium. So they are kept up to 2 months of age, gradually sorting by size and reducing their number. Fry is caught not with a net, but with a saucer or other container. This makes them easier to get and count.

Sorting is carried out according to the rejection principle. They remove juveniles with defects, juveniles lagging behind in growth, etc. Ultimately, they get purebred goldfish.

Unfortunately, defective and non-standard juveniles are killed. Firstly, because, as a rule, she does not survive on her own, and secondly, even if she survives, nothing good will grow out of her. With its further maintenance, you risk getting outbred offspring. bastards, well, if you go further, then the fish will simply degenerate into a goldfish.

At first, the scaly juveniles of goldfish have a silvery-gray color, like the progenitor of the goldfish. Coloring appears only at the age of 3-5 months. To improve the brightness of the color of fish, it is recommended to “sunbathe” the light should be diffused. In an artificial reservoir, no shading is needed, on the contrary, the aquarium is intensely illuminated with lamps. It is worth noting that the color of goldfish can change practically all their life.

Scaleless fry do not go through the aforementioned period of silver coloration and already at two weeks of age begin to stain their final color.

Young goldfish are very capricious and prone to disease. To avoid the loss of offspring, you should regularly monitor the cleanliness of the aquarium, aeration and filtration. Constantly monitor the population. do not forget to resettle as you grow.

When breeding goldfish, species crossing must be strictly observed. All goldfish can interbreed with each other (for example, veil-tails with comets).

Summing up, you can make a short list of what you need to breed goldfish:
