How to breed goldfish in an aquarium

maintenance, care, compatibility

Goldfish kept in aquarium in good conditions become ready for breeding at about the age of one year. By this time, the goldfish male acquires small growths that appear on the anterior pectoral fins, and the female has a more prominent abdomen.

For breeding goldfish in the aquarium should be one female and two or three males. The optimum volume of the aquarium is 2-3 buckets, and the water temperature in it is 22-24 ° C. Sand at the bottom of the aquarium is undesirable, since without it the eggs will be better preserved.

But the small-leaved plants must be present: ellodey, peristristis, fontinaris or others. An aquarium in which goldfish will spawn should be illuminated for 24 hours by the sun and an electric lamp.

In spring, young male fish begin to stalk females. The optimal spawning period for goldfish is May-June. Therefore, if you notice that the fish are ready to spawn before the beginning of April, they should be seated in different containers.

To delay spawning, you can reduce the temperature of the aquarium water. Before spawning goldfish need to be fed with bloodworms, daphnia, and earthworm.

On the eve of spawning, the males begin to actively chase the female. This activity increases and goes into violent pursuit on the day of spawning.

Spawning goldfish lasts about 5-6 hours. The female, swimming between the plants, spawns, and the males fertilize her. Sticky eggs stick to the surface of underwater plants.

Initially very small, their diameter is only 1.5 mm. The color of the eggs is at first amber, but then they turn pale, and it becomes quite difficult to look at them.

After spawning, the fish should be transplanted into another container, as they can eat eggs. From 4-5 days fry will begin to hatch.

For their better development, you can reduce the water level in the aquarium. In order to destroy unfertilized eggs, launch snails into the aquarium.

From 100 l., In such an aquarium, you can put one, maximum two scalar. Under good conditions, they grow into fish of impressive size, and given their wide fins, it is better to buy an aquarium from 250 liters for them.

About how much you can keep fish in X liters of aquarium, see HERE (at the bottom of the article there are links to aquariums of all volumes).

The fish are omnivorous and the feed is absolutely not whimsical. They are happy to eat dry, live food and substitutes. Like many aquarium scalar dwellers love live food: moth, artemia, choke, cyclops, daphnia.

The feed by scalaries is taken from the surface of the water and in its thickness, the fish do not disdain to walk along the bottom after collecting the remnants of food.

The scalar has a peculiarity – they can refuse to eat for up to 2 weeks. So if your scalar does not eat – there is nothing wrong with that.

Feeding aquarium fish must be correct: balanced, diverse. This fundamental rule is the key to successful keeping of any fish, be it guppies or astronotuses.

Article “How and how much to feed aquarium fish” talks in detail about this, it outlines the basic principles of the diet and feeding regime of fish.

In this article, we note the most important thing – feeding fish should not be monotonous; both dry and live food should be included in the diet. In addition, you need to take into account the gastronomic preferences of a particular fish and, depending on this, include in its diet ration either with the highest protein content or vice versa with vegetable ingredients.

Popular and popular feed for fish, of course, are dry food. For example, hourly and everywhere can be found on the aquarium shelves of food company “Tetra” – the leader of the Russian market, in fact, the range of feeds of this company is striking. In the “gastronomic arsenal” of Tetra are included as individual feeds for a certain type of fish: for goldfish, for cichlids, for loricarids, guppies, labyrinths, arovan, discus, etc.

Also, Tetra has developed specialized foods, for example, for enhancing color, fortified or for feeding fry. Detailed information on all Tetra feeds, you can find on the official website of the company – here.

It should be noted that when buying any dry food, you should pay attention to the date of its production and shelf life, try not to buy food by weight, and also keep the food in a closed state – this will help avoid the development of pathogenic flora in it.

In nature, scalars live in northern South America

The body is round and very flattened at the sides. It has a very elongated back and anal fin, which gives the fish the shape of a crescent. Natural – the natural color of the scalar is silver with black transverse stripes; however, as a result of successful selection, various color scales were obtained, for example, a marble scalar, a two-color, red, black, zebra scalar and others.

In addition, the veil form of the scalar is derived – with even longer fins. Angelfish are large, sweeping fish, can reach up to 15 cm in length, and even more than 25 cm in height in the forest.
Story of the angelfish

The Latin name Pterophyllum was given by the famous Austrian zoologist I.Ya. Heckel in 1840 and it translates as “pteron” – a feather and “phyllon” leaf, and together a “winged leaf”.

Before Heckel gave the name Pterophyllum, this fish was already repeatedly described in 1823. Martin Heinrich Karl Lichtenstein, who gave her the name Zeus scalaris. And in 1931, the fish was described by Baron Jord Léopold Frederik Bagobert Cuvier.

He called it Platax scalaris. It was the scalar and the market name “Blattfische”, translated as leaf fish.

This name was given by G. B. Sagratski, who first managed to bring these fish from Rio Negru to Germany.

Actually, under this name, for the first time, they found themselves in Europe, however, such a name did not eventually stick. Abroad, the angelfish is called “Angelfishes” or simply “Angel”, in Germany “Segelflosser”, which translates as a sail.
In some sources, it is said that for the first time the scalars appeared in Europe in 1909, but this is not the case. From this year, they “dovozili”, but alas, the dead.

Only in October 1911 was it possible to bring a living scalar. And only from this moment on in Europe did the “aquarium-scalar boom” begin: description, disputes, articles in journals, attempts at breeding, etc.
The first successful breeding of scalar in artificial conditions occurred in 1914 at the aquarist from Hamburg – I. Quancar. His success was repeated only a year later by an aquarist from the USA, U.L.

Polynn. It is worth noting that at that time the secret of reproduction was kept in the strictest secrecy – the scalar was very valuable. However, everything is secret when it becomes clear.

Since 1920, breeding scalar gains mass.
In Russia, the scalars multiplied for the first time in 1928. This happened at our aquarist, Mr. A. Smironov – in the evening he went to the theater, and at home in the aquarium he had a hot water heater.

The temperature of the water in the aquarium rose to 32 ° C and the scalar spontaneously began spontaneously. As a note of humor, I would like to say that the Russians are as always – at random and anyhow.
But, aquarists did not stop at the successful artificial breeding of scalar. The second half of the twentieth century was marked by inexorable breeding work on scalars.

In 1956, a veil scalar was bred. In 1957, a spectacular black scalar was introduced in the USA.

In 1969, again by the American Charles Hashem, a marble scalar was obtained.

Breeding, reproduction and sexual characteristics of scalar

Everyone wants to know the sex of their goldfish, unless of course the goldfish are not intended solely for decorative purposes. Real goldfish fans usually want to get offspring from them, and here the definition of sex is of particular importance.

There are several ways to determine the sex of goldfish.

During the spawning period, males of goldfish are easier to identify than females. Males develop tubercles or white bumps along pectoral fins and gill covers.

In addition, the male teeth on the pair of front fins form serrated teeth, the so-called “saw”. Females become slightly asymmetric, especially in the abdomen.

They look bloated.

In the photo clearly visible tubercles casting the Golden male from the female.

At the end of the spawning period and after several spawning spawns in some males, the thoracic region becomes rigid. It is rather difficult to determine this state, therefore, those who are not able to do this can be comforted by the realization that not many can distinguish a goldfish female from a male.

Here are some more ways to determine the sex of a goldfish, but even they are useless, if there is no fish for at least a year*, that is, if the fish has not reached puberty.

1. Males have an outgrowth extending through the posterior part of the ventral fin to the anus. In females, this growth is either completely absent or much smaller.

2. In females, the area between the ventral and anal fins is soft, and in males it is hard.

3. Although it is difficult to see, but the anus of females is round and convex, while the anus of males is thinner and concave.

4. The male’s abdominal fins are pointed, and the female’s fins are round and shorter.

5. The color of the females is brighter and they are more active. This method will undoubtedly help distinguish the female.

6. You can run the female goldfish in the aquarium and watch the reaction of the other goldfish. Males will swim to a new fish, and females will not show interest.

* Do not be surprised if in the pet store when buying goldfish, give your question to the male and the female, you will be told that this is not possible! Sex differences in the family of goldfish appear only with the onset of sexual maturity, i.e. after 1 year.

The Cockerel Fish: content, compatibility, reproduction, photo-video review

The question of the volume of the aquarium for these fighting fish is a separate topic.

Alas, almost all pet stores sell these luxury fish in 250ml. glasses, while sellers tell people that these are “unique fish”, they say they do not need oxygen, filtration, that they feel great even in a glass.

Do not believe the sellers of pet stores, their task is to sell the goods, and what will happen next with the fish, with you and the tears of the child who saw the cockerel floated up with a belly up – DOESN’T INTEREST THEM. And yet, you would know how many cockerels do not live out of pet stores until the time of purchase.

You would sincerely feel sorry for these innocent fish.

Yes, of course, cockerels are hardy fish, in natural habitat they live in muddy, silted, oxygen-free rice fields. But this does not mean that they can be kept in a small glass with water.

Firstly, because the conditions of keeping of any animal should be as close as possible to the natural living conditions. Monkeys must jump in trees, birds fly, and fish swim.

When the cockerel fish just hangs in a glass, dropping the fins – this is actually a sad sight. Secondly, in the cup, vase and other small vessels there is no biobalance at all. In the rice field, for example, various biochemical processes take place that purify water from various poisons (ammonia, nitrites and nitrates), these processes are absent in a glass with water, the poisons accumulate, the immunity of the fish weakens and it dies.

Biological equilibrium in artificial conditions can be achieved only in spacious aquariums, and the more, the better.

So, the minimum amount of aquarium (decorative vase, etc.) for cockerels should be 3 liters. To call such a vessel an aquarium is difficult in all senses, and therefore, if we talk about creating a full-fledged aquarium, the minimum volume for one individual should be 5-10 liters. In such an aquarium, you can put a mini-filter, such an aquarium can be beautifully — naturally, you can plant aquarium plants, adjust the biobalance, and taking care of such a reservoir is much easier than washing the “pot” weekly, while delivering great stress to the fish.

A good volume for a pair of Bette is considered an aquarium from 20-30l.

About how much you can keep the fish in the X aquarium, see HERE (at the bottom of the article there are links to aquariums of all volumes).

Requirements for the care and maintenance of cockerel fish

From the above, we can conclude that in one, a small aquarium, you can contain only one male cockerel. If the aquarium is large – from 100l. You can try to plant the second male or make transparent partitions in the aquarium, for example from plexiglass, pre-drilled holes in them to circulate the water in the aquarium.

In addition, I advocate the creation of a natural – natural environment in an aquarium. The aquarium can and should be decorated with stones, grottoes, snags, as well as living aquarium plants.

Lighting should not be very bright, preferably the presence of filtering. The aquarium itself should not be filled with water to the brim, you need to leave 7-10 cm and be sure to cover the aquarium. All labyrinth fish and cockerels in particular breathe atmospheric air, swallowing it from the surface of the water.

In the absence of airspace or access to the surface of the water, the fish will suffocate. A lid is needed to ensure that the air swallowed by cockerels from the surface of the water is not too cold.

An aquarium with cockerels can be equipped with artificial plants, but still, if you have the opportunity, purchase live aquarium plants. With live plants, the aquarium looks more natural, the plants themselves contribute to biological balance, and the males can also use them for spawning and creating a foamy nest.

Of unpretentious plants for cockerels can recommend: vallisneria, rogolini, cryptocorynes, other not complex plants.

Feeding and diet of cockerels: they are not whimsical in food, they are happy to eat both dry and live food (Artemia, bloodworm, etc.). The males eat any brand-name dry food, but advanced aquarium brands have developed special ones for them – individual foods that are best suited. Feeding aquarium fish should be correct: balanced, varied.

This fundamental rule is the key to successful keeping of any fish, be it guppies or astronotuses. Article “How and how much to feed aquarium fish” talks in detail about this, it outlines the basic principles of the diet and feeding regime of fish.

In this article, we note the most important thing – feeding fish should not be monotonous; both dry and live food should be included in the diet. In addition, you need to take into account the gastronomic preferences of a particular fish and, depending on this, include in its diet ration either with the highest protein content or vice versa with vegetable ingredients.

In nature, live: Southeast Asia: Indonesia, Thailand, Cambodia, Malaysia, Vietnam. They live in stagnant, oxygen-free waters – puddles, ditches, rice fields.

Description: Very beautiful fish, its veil tail and fins just fascinate. The color of the fish is different. The most common ink color with a reddish tint.

Males are colored much brighter, fins are longer than those of females. The size of the fish is 5-10 cm.

Body laterally compressed, elongated, oval. They have cycloid scales, pointed pectoral fins, upper and tail fin of a rounded shape, the lower fin originates from the head and ends at the base of the tail.

The history of cockerel fish

The first mention of the fish dates from the beginning of the nineteenth century, it was then that the people of Siam paid attention to these small, but lively and aggressive fish. Next, the Siamese began to cross wild individuals Betta and got a new kind of fish, calling it “biting fish.”

A couple of copies of these “pieces” in 1840. King of Siam handed over to Dr. Theodor Cantor, who in 1849 gave them the name Macropodus pugnax. After 60 years, the British ichthyologist Charles Tate Regan renamed them “The Beton Fish”, arguing that the Macropodus pugnax species already exists in nature.

It is known that the cockerel fish appeared in Paris in 1892, in Germany in 1896, and in 1910 appeared in the United States with Frank Locke from San Francisco, California. Through the selection of these fish, he received a “new” fish, calling it Betta Cambodia – one of the first color variations of Betta Splendens. The history of the appearance of Bette in Russia is not truly known.

There are several versions. The first is associated with aquarist VM.

Desnitsky, who allegedly in 1896. brought from Singapore exotic species of fish and plants, but it is not known for certain whether there were any cockerels among them. The second version says that the aquarist V.S. Melnikov approximately in the same period spread a number of labyrinth fishes in Russia.

By the way, a competition for the best fighting fish was established in his honor. And the latest version says that the fighting fish were brought in by the Frenchman Seysel, and all descendants from Russia and Europe went from his fish.

Types of Bette and Petushki selection forms

The first thing I want to say is that the cockerel fish (Betta splendens) is one of the Bett species. Bette species should be distinguished from Betta splendens breeding forms.

On the Internet, everywhere breeding forms of a rooster are given for species, which is not correct!

So, the Bette’s species include: Betta picta (Betta picta), Betta striped (Betta taeniata Regan), Betta smaragdova (Betta smaragdina Ladiges), Betta untamulata (Betta unimaculata), Betta black, she’s also the dwarf, Cockerel black, she’s black, she’s black, she’s black, she’s black, she’s black, she’s black imbeIIis ladiges), Cockerel (Betta splendes).






And here, the selection forms of the Cockerel (Betta splendes) include:

In size and shape of the fins:

– Veiltail fighting fishes or “veil cock”

– Deltatail fighting fish

– Giant or royal fighting fish

– Crescent-tailed warrior fish

– Round-tailed fighting fish

– Crescent-tailed warrior fish

– Deltatail fighting fish

– Flagtail fighting fishes

– Poster fighting fish

– Crownstail fighting fish

– Poster fighting fish

– Crosstail fishes

– Two-tailed fighting fish

– other


By color:
Multicolor “multicolor”, two-color, one-color.
