Astronotus: content, compatibility, breeding, photo-video review

Astronotus very aggressive fish. Their temperament, their burrows does not allow keeping them with other fishes.

Moreover, they have intraspecific aggression. Therefore, the correct recommendation would be – the content of a pair of astronotus in a separate species aquarium.

Maybe someone will argue: “How so? I have five asters living with other cichlids, and even with pterigoplicht !? ” Yes, of course, to the astronotus can be hooked big brothers in the family or other fish that do not give themselves to hurt.

But in this case, you must be prepared for the fact that one fine day the fight will begin. As a rule, such a moment occurs during puberty and spawning.

Certainly astronotuses are not compatible with small and medium fish. Goldfish they perceive as a snack on the aperitif.

Speaking of compatibility, it should also be said that the content of astronotus, even with the most hard-leaved plants, is problematic. As a recommendation, you can advise to decorate the aquarium anubias, cryptocoryne, ekhinodorusami.

Many novice aquarists can again object to our opinion, however, the recommended volume for a pair of astronotus is an aquarium from 500 liters. Such a volume will be comfortable for them. Of course, astronotus can be found in aquariums of 250 liters or less, but this is not the norm!

Such volumes lead to the “tightening” of fish, to disease and early death. In addition, we must not forget that the astronotus is a big fish that emit a lot of waste products.

The content of astronotus in small volumes leads to the accumulation and high concentration of poisons: ammonia, nitrite and nitrate.

Astronotus is one of the most famous and big fish in the genus Cichlids. They can reach 30-35 cm.

Homeland astronotus is South America – the Amazon, the system of the rivers Paraná, Paraguay, Rio Negro.

The body of the astronotus is elongated and flattened at the sides. The head is large, bulging forehead and large expressive eyes.

The fish has large, rounded fins. There are many multicolored variations of astronotus. The most common: natural color, copper color and albino form.

Fish is able to change color under stress.

Aeration, powerful filtration, and regular water changes (30% of the water) are necessary for their maintenance. Particular attention should be paid to filtering – it should be powerful (the second filter will not be superfluous).

The aquarium can be decorated with large stones and snags, the decor should not be sharp.

Also, there is one nuance in the content of these fish. Astronotuses constantly “tinker” the aquarium: they dig the ground, pull out and gnaw the plants, carry small stones, do not give rest to aquarium equipment.

In this connection, the scenery and equipment of the aquarium should be well secured, it is advisable to abandon the soil and lay large boulders + snags. If the ground still fits, it is better to use the smallest fractions and lay a layer of 1-2 centimeters.

In the feed ration of astronotus rises: large bloodworm, earthworms, meat, bullish heart, fillet of sea fish, artificial food. In pet stores you can find quite a lot of different types of food for astronotus.

These fish are voracious, in order to avoid problems with the gastrointestinal tract is recommended to feed them once a day and be sure to arrange fasting days.

Additional feeding recommendations: crown, lively medium-sized fish, tadpoles, frogs, squid, shrimp. Vegetable foods should be included in the diet: mashed black bread, oat flakes, lettuce and spinach leaves.

It is important to correctly alternate all types of feed. Feeding should not be monotonous.

One should not give preference to live fish, as astronotuses quickly get used to it and refuse other food. From meat products it is better to use beef heart, cut into small pieces.

Feed the heart to the fish no more than once a month, otherwise they may become fat and stop breeding.

Feeding any 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.

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.

We also recommend that you read the materials – recipes homemade feed for aquarium fish.

How to distinguish male from female astronotus? Sexual dimorphism is poorly developed.

The sex of an adult astronotus can be accurately determined only by the primary sexual characteristics that appear during spawning.

Below are some signs by which you can try to distinguish an adult male from an astronotus female:

1. For females of astronotus is characterized by a more rounded belly.

2. The distance between the eyes of males is usually greater than that of females.

3. The back of the female in the anal fin region is a pear-shaped, while, as in males, it is most often even, with no noticeable bulges.

4. It is believed that males are larger than females, but this item can only be used if your fish lived in the same aquarium. And to choose a female or male in the store, especially if they are different in age, is almost impossible.

5. The abdominal fins in males are slightly longer and more pointed at the ends than in females.

6. The frontal part of the male body may be more convex than that of the female.

These signs are relative and can only be used as a hypothesis about the field of a particular astronotus.

The main problem in the breeding of astronotus is the formation of a pair. For this, razvodchiki usually take a flock of astronotus fry, up to 15 tails, place them in an aquarium from 300 liters and feed them abundantly for a year (until puberty). When this happens, the fish are divided into pairs and occupy a separate area in the aquarium.

The territory starts to be guarded, all trespassers get cuffs. From this point on, fish are transferred to moderate feeding.

Next, the selected, formed pair is deposited separately in the spawning tank and stimulate spawning – raising the temperature to 30 degrees and water changes.

For a couple of hours before spawning, the female has an egg-deposit, and the male has a seed tube. At this time, the pair is brightly colored.

Carefully cleaning the bottom of the aquarium or stone, a couple of manufacturers lays from 500 to 1500 large eggs, beige.

Astronotus is a freshwater fish of the Cichlid family (Tsikhlovye), which was discovered in 1831 by J.R. Agassiz, the famous zoologist from Harvard.

The natural habitat of fish is the waters of South America. Often it can be seen in the basins of the Amazon, Orinoco and Rio Paraguay.

Also, the fish was brought to Australia, the USA and Singapore, where it violated the ecological balance, destroying native species of fish.

Astronotus is a very hardy fish that tolerates conditions with low oxygen content and a water temperature above 28 ° C. Like a tropical fish, it can not be kept in cool waters, otherwise it will die. The temperature regime of the South American rivers throughout the year is kept at 22-34 degrees Celsius.

This means that conditions of detention in a seine must correspond to this temperature. The optimum range of acidity of water: 6.0-8.0 pH.

In the natural environment, fish are found in dark waters, which means they prefer an acidic environment. Wild fish of this species is rarely available, nowadays it is bred in fish farms.


Astronotus is not a very neat fish, although it is unpretentious. When the pet gets used to life in the aquarium, it starts digging up the soil, destroying the scenery, even the technical equipment of the tank. Living plants can survive only if they have deep and powerful roots, or they are planted in a pot.

They may unexpectedly rearrange the decor, especially during spawning and feeding.

Sand with stones, snags and decorative sprigs will be suitable as soil – this will create a kind of natural biotope in an aquarium. Content is recommended in subdued lighting. Install an external filter in the tank that will purify the water.

Astronotus loves high protein food, so the remnants of such food can quickly pollute the water. With weak filtration, ammonia and nitrates will appear in the water, which can lead to a deterioration in the health of the pet.

Weekly should be replaced by 20-30% of water for fresh. It is possible to install an aquarium heater outside the tank so that the fish will not break the underwater installations.

Permissible parameters of the aqueous medium for the content: temperature 22-26 ° C, acidity 6.5-7.5 pH, hardness 5-20o. The duration of these fish in captivity is 10-12 years, if they are provided with proper care.

After studying the gastrointestinal tract of astronotus caught in the wild, it was proved that they are omnivorous fish. They eat small fish, zooplankton, aquatic and terrestrial vegetation, crustaceans, insects, small species of rodents.

Studies in 1990 showed that the main diet of wild specimens – animal food, vegetable is not more than 30% of the total diet.

Watch the feeding of the astronotus in the general aquarium.

All aquarium fish species astronotus are able to eat animal, vegetable, frozen and artificial food. Very fond of special granules for cichlids.

Small worms can be given to young fish, sexually recommended to give earthworms, grasshoppers, crickets, locusts, shrimp meat, mussel meat. Also, these fish will not give up ice peas, spinach leaves and lettuce.

Overfeeding is very unhealthy, can cause disorder of the organs of the gastrointestinal tract.

Some owners can give them beef heart and chicken meat. If given very often, it will lead to deformation of the internal organs and blockage of blood vessels due to the fat content in the meat.

Beef heart can be given very rarely, or completely abandon it. Of the meat food, astronotus loves the most viviparous fish (guppies, swordtails, placium).

No matter how cruel it looks, they are sometimes bred specifically for feeding larger cichlids.


Caught in the pond, or purchased fish can be extremely harmful to health – there is a risk of infection in the aquarium. Astronotuses need vitamin C, which in nature they are derived from fruits or other plant-based foods.

Leaves of lettuce and spinach, sliced ​​zucchini and zucchini will make the diet more varied and useful.

Who do these fish get on with? Good compatibility with other fishes will simplify care of an aquarium. Many cichlids are peaceful fishes, quick-witted, they quickly get used to people, they can even take food from their hands.

But compatibility in the general aquarium is excluded with fish that easily fit them in the mouth. In a spacious aquarium of 1000–1500 liters, astronotus fish can be kept with other fish. Among them: large haratsinovye – Metinnis, Mileus, non-aggressive large cichlids – geophagy, loricaria, doradyds, gerosa, as well as South American arnovans.

All the fish that are geographically close to them will be suitable as neighbors, therefore compatibility is also possible with cyprinids, loach clowns, reddish mastelambels.

Astronotus reaches its maximum size by 4 years, so their maintenance is possible only in a large aquarium, where there is at least 100 liters of water per pair. Coarse sand and gravel with large stones will serve as good soil. Astronotus is not picky about water parameters, but it needs high-quality filtration and aeration.

Temperature of water is 22-27 ° С, hardness is up to 20 °, acidity is up to 7.5.

To decorate the aquarium should not be planted live plants, as they will not be able to resist the attacks of astronotus. You can take a chance by planting an Echinodorus, Bolbitis and a Thai fern in a pot.

Artificial plants should also be firmly strengthened with stones at the ground. From floating plants fit elodey, rogolistnik, perennial.

Red

The reproduction of astronotus is recommended to achieve the achievement of their age of two years in a separate spawning. Breeding astronotus requires the joint maintenance of several fish, so manufacturers will be able to choose their own pair.

In order for the reproduction of fish to proceed comfortably, it is necessary to place 5-6 pieces in an aquarium per 300 liters and ensure good filtration in it. Presence of soil is undesirable.

The spawning of astronotus proceeds by the darkening of the color of the fish, spotted divorces on the body become red. It is possible to breed fish in the general aquarium, but during this period the fish become aggressive and dangerous for their neighbors.

Propagation is stimulated using a variety of feeding, and the substitution of water with boiled water with a temperature increase of 3 ° C. The remaining water parameters remain the same. In the spawning aquarium, you should install several large stones on which the fish will lay their eggs.

How many eggs astronotuses are able to postpone, depends on the conditions of their maintenance, usually females give up to 1000 eggs and are distinguished by special parental care.

Astronotus protects caviar, fanning it with its fins, drives away other fish and removes unviable eggs. Fry begin to swim to day 10 and feed on the parental epithelial secret.

Then they can be fed with small cyclops, egg yolk, chopped pipemaker, nematodes and live dust. Young fish is painted black with white specks.

Unfortunately, representatives of this type of fish get along far not with any aquarium inhabitants. Nevertheless, there are such types of fish with which they are able to lead a normal and relaxed lifestyle, namely, with tsikhlazomami, pterygopliche and synodontis.

The maintenance of astronotus with other fishes is quite a simple matter, they can be companied in an aquarium with Central and South American cichlids of a moderate nature, not aggressive, but not too calm. In this case, both of these representatives of the underwater kingdom must get into the aquarium at the same time, otherwise they will recapture the territory.

Many wonder what to do if astronotics fight? In this case, you can either lower the temperature of the water, or remove one representative for a while.

Despite the fact that astronotus’s compatibility with other fish is not very great, nevertheless, their neighbors can also become: arovan, shark catfish (Siamese pangasius), Indian knifefish, parrot cichlid, shark bal, barley-shaped, hoplosternum beige as well as porous perigopolis.

Deciding to have such a fish in yourself, be prepared for the fact that you will not be able to live the wonderful living corner with a lot of plants. Since this “harmful” fish will either eat algae, or simply dig them up. They love to turn everything upside down, move it from one place to another, stir up the soil.

Therefore, it is better to purchase ordinary artificial plants, massive snags and large heavy stones for decoration.

For the maintenance of astrotonus in an aquarium as a pair, they will need a “lodge” with a volume of not less than 100 liters, with good filtration and the lid must be closed, otherwise the fish will be able to jump out of the aquarium. Water temperature can vary from 18 to 28 degrees. Feed these amazing and intelligent fish can be insects, larvae, worms, tadpoles, meat 1-2 times a day.

If you give them due attention, you can feed the astronotus from your hands and even stroke it.

Astronotus cichlid Oscar care, spawning, description, feeding.

If an astronotus lives in your house, it is quite difficult to maintain cleanliness in the pond. Acquired external biofilter will be a good helper for you.

He successfully cleans the aquarium from ammonia, which accumulates in the water, as well as a large catfish, which is happy to eat the remnants of food of its neighbors. Astronotuses are very sensitive to the lack of oxygen, so pay special attention to aeration and water filtration.

Once a week it is enough to replace the third part of the water so that the health of your fish is in order. Astronotus poorly tolerate cold water.

So that your pets do not hurt, keep the temperature of the water in the aquarium within 23 -27 ° C.

Feed your cichlid with live or frozen fish or small live fish a couple times a day. Astronothus is a big lover of food and, in order not to feed him, give him as much food as he can eat in two minutes.

You can even arrange fasting days. Like all predators, astronotus like raw meat, beef liver and heart.

They eat squid, tadpoles and snails, earthworms, and also bloodworms, flies and grasshoppers. If you do not have the opportunity to purchase animal food, you can feed astronotus with special feeds for cyclides.

Some fish lovers prepare food for the future, while keeping it crushed in the freezer.

Breeding

For the breeding of Astrutus, a group of 4-5 young fish is deposited in a separate aquarium. They form pairs, and the best of them are planted to spawn. Astronotuses become sexually mature by 2 years.

It should be borne in mind that, despite the size, these fish are fearful, they react cowardly to noise, which should not be during spawning. It should take place in another spawning aquarium, since the neighbors will create extra noise and a threat to the offspring of Astronotus. Aquarium should be equipped with aeration and filters.

Water in it should be a temperature of 26-28 degrees, soft. Ground in spawning is not required.

You can restrict yourself to a large and flat stone, where the female Astronotus will lay eggs.

It should be noted that during spawning in fish the color changes. Males become very caring, carefully cleaning the surface of the stone.

Only after this spawning begins, which lasts 4-5 hours. The female lays about 1000 eggs at a time.

Astronotus – fertile fish. Manufacturers carefully care for offspring (eggs).

They fan them with fins, and the larvae just watchman. Between the transformation of larvae into fry a week passes.

Juveniles begin to feed on their own.

The first days it is recommended to feed it with daphnia and artemia, and then add the chopped strawberry to the food. Fry of this fish grow unevenly.

For this reason, they are better sorted. At the age of one month the size of the fry reaches 2 centimeters.

Latin name: Astronotus.

Order, family: perch-shaped, cichlids.

Parameters of water for the content of astronotus

Water temperature: 22-28 С

Ph acidity: 6.5-7.5.

Water hardness dH: up to 25.

Aggressiveness: 99.99% is aggressive.

Lifespan: more than 10 years. Astronotuses are aquarian long-livers.

Astronotus very aggressive fish. Their temperament, their burrows does not allow keeping them with other fishes. Moreover, they have intraspecific aggression.

Therefore, the correct recommendation would be – the content of a pair of astronotus in a separate species aquarium.

Maybe someone will argue: “How so? I have five asters living with other cichlids, and even with pterigoplicht !? ” Yes, of course, to the astronotus can be hooked big brothers in the family or other fish that do not give themselves to hurt.

But in this case, you must be prepared for the fact that one fine day the fight will begin. As a rule, such a moment occurs during puberty and spawning.

Certainly astronotuses are not compatible with small and medium fish. Goldfish they perceive as a snack on the aperitif.

Speaking of compatibility, it should also be said that the content of astronotus, even with the most hard-leaved plants, is problematic. As a recommendation, you can advise to decorate the aquarium anubias,cryptocoryne, ekhinodorusami.
