Aquarium fish compatibility


Compatibility of aquarium fish: tips and tricks

Selection of fish for your aquarium is a very interesting task, but not easy. The choice is truly huge, and we have to take into account not only the features of the appearance of the fish, but also many other factors. One of them is their compatibility, that is, the ability of different species to live together and feel comfortable in the general aquarium. The main principles of this compatibility will be discussed in this article.

The reasons for the impossibility of sharing some species of fish - and any other living creatures - are intuitively understandable: they live in nature in different climatic zones, in different conditions, and even in the case of close proximity they can be in different relationships with each other, for example, being a predator and the victim. And if we are philosophical about the fact that in the natural environment of the environment some fish eat others, few people want to witness such a picture in their aquarium. In order to avoid a situation in which fish in an aquarium suffer from their neighborhood, in selecting them you need to know and take into account several basic rules.

Compatibility Types

Fish species can be:

  • fully compatible;
  • completely incompatible;
  • conditionally (limited) compatible.

The first two categories are clear, the third includes species whose coexistence is possible under certain conditions (such as the size of an aquarium, its proper zoning, the presence of shelters, or even particular features of character and life experience of specific fish individuals). I must say that sometimes - very rarely! - in aquariums, somehow, completely incompatible species manage to get along, but these are exceptions.

To facilitate the selection of fish there are species compatibility tables, they are in the special literature and on many aquarium sites. But let us try to formulate the principles by which the compatibility of the fish is determined.

Basic principles of aquarium fish species compatibility

Similar conditions of detention

It is obvious that in one aquarium it is impossible to settle fish that require different environmental parameters: water temperature, hardness, acidity, light, the presence and strength of the flow, and so on. Often similar requirements to the conditions of detention are related species of fish or species that live in nature in the same biotopes.

Specific aquariums are built according to this principle of selection of fish: the now popular tsikhlidniki, aquariums with various short-headed goldfish or with viviparous - guppies, petillia, and mollies. Interesting and geographical aquariums (for example, the aquarium "South-East Asia"), recreating the conditions of a locality, where people live fish of different families living in this area.

Predators and prey

Here, too, everything is simple and clear: you can not keep together predatory fish and their potential prey. That is, predators, of course, will be grateful to you for this - it is always more pleasant to catch and eat a young neonchik than to choke on dry food (and it is more useful for health). But here the future victims of this alignment are unlikely to be happy. Therefore, before buying fish, you should definitely find out whether they are predators (yes, cute little fish from the pet store can easily grow into ruthless killers), and choose the right size for their neighbors.

Size matters

Large fish, even if they are not predators, are not recommended to live with fish trifles, as representatives of the latter will always feel threatened and in stressful conditions. This will adversely affect their health, longevity, and decorative value: firstly, the color can fade from feelings, secondly, fish will hide all the time, it will be uninteresting to watch them, and it is almost impossible. In addition, it is likely that a completely peaceful, non-predatory large fish will inadvertently swallow a small one, because even such lodges as goldfish will catch prey if it swims into their mouths. Conclusion: the fish in the aquarium should be of a comparable size and at least should not fit together in the mouth.

Opposites do not converge

Unlike people, whose temperaments often complement each other, fish feel more comfortable among individuals with similar behavior. Rather, nimble, lively and active fish (such as, for example, zebrafish) usually pay little attention to phlegmatic and brooding gourami or guppy, but the latter, surrounded by fast and nimble neighbors, may experience stress and discomfort. In addition, they often simply do not get food, as energetic neighbors eat it faster than fish-mattresses have time to get to this food.

Of course, not everyone wants to have a continuous melteshenie or, conversely, a sleepy kingdom in an aquarium. Therefore, you can pick up fish with different temperament, but with the condition that they will occupy different layers of water, for example, calm bottom catfish and fast schooling fish in the middle layers of the aquarium.

Territorial aggressors

There are fish species that attack other inhabitants of the aquarium, not because they see food objects in them, but to protect their territory. Territorial fish protect their family spawning areas, such as cichlids, and in the case of algae-eating fish (Labo, Girinoheylus) - their pastures. In different types of aggression can be directed either only to individuals of their own species, or to the entire population of the aquarium. Therefore, acquiring a fish, you should definitely find out whether it is territorial and how this property manifests itself in it. In the descriptions of the species, it is indicated how best to settle them: singly, in groups, in pairs, whether other species can live in an aquarium with them, and what kinds of species these should be.

Gentle beauties

Fish that, as a result of breeding, acquired unusual for their species hypertrophied features (veil fins, growths on the skin, greatly enlarged eyes, albino coloring) are usually much more tender than their wild type congeners, and they should be treated with special care. . It is recommended to place goldfish in telescopes, astrochets, voiletails, pearls in species aquariums, where even long-bodied rocks of scoria should not be, not to mention different bullies, such as barbs. The same applies to other fish with long fins. You can not settle them with those who are ready to bite these fins.

Albinos of some species, for example, Labo, do not withstand competition with their relatives of the usual color and lose battles for the territory, which gradually leads to their death.

What to do if you really want to populate low-compatible species in an aquarium?

Species that are biologically poorly compatible (that is, those that need very different water parameters) cannot be lodged together. With behavioral compatibility (when the fish do not match in temperament or some of them are territorial), you can experiment. General tips are:

  1. The aquarium should be spacious and not overcrowded, it should be zoned with the help of decorations and tall long-stemmed or long-leaved plants (so that there is no other view from one part of the aquarium) and provide a variety of shelters. For fish that prefer the upper layers of water, it can be dense thickets of plants and tall, intertwined snags, for bottom fish - grottoes, shards, coconut shells.
  2. Make sure everyone has enough food. Food should be given so that it falls into different parts of the aquarium, and the fish did not need to fight for it, and the timid did not even need to swim far out of their corner. Seaweed fed with lettuce, cucumber, zucchini, which are also located in different parts of the aquarium.
  3. Buy fish of different species young and grow them together, so that they have the opportunity to get used to each other.

It must be remembered that settling into an aquarium of incompatible species is a big risk, and to be ready to change the design of the aquarium, equipping new zones and shelters, treat battered or diseased fish and periodically buy new ones to replace the dead. But aquarism is interesting in that it gives us a wide range of possibilities: we decide for ourselves whether we want to see a peaceful idyll in the aquarium or a boil of African passions. The main thing is that this decision be deliberate.

A short video story about the compatibility of aquarium fish:

Compatibility of aquarium fish

In any interior aquarium adds elegance and comfort. Floating fish soothe and give pleasant emotions. Therefore, the content of this underwater world is not fashion, but the desire to decorate the atmosphere of your home in a special way. Any aquarist needs to be aware of the concept of compatibility of aquarium fish.

Choosing representatives of the underwater world for an aquarium, it is important to know that there are many fish species and each has its own habitat conditions, behavior, water requirements, etc. Therefore, the main thing is not to make the most common mistake - to try to keep predators and harmless fish together in one aquarium. . For example, aggressive cichlids are unlikely to get along with calm guppies. And this confirms the fact that the compatibility of fish in an aquarium requires close study.


Usually compatible aquarium fish is not difficult to pick up, but some novice aquarists attach little importance to this, and as a result unpleasant moments occur. So some representatives of the water kingdom can become dangerous not only for neighbors in the aquarium, but even for the owner himself, for example, electric eel or piranha. And some fish, such as pacu, red-tailed catfish - simply grow too large.

The task of an aquarist is to find out as much information as possible about a particular type that it is going to contain. After watching the video, literature, studying a special table of compatibility of aquarium fish should make a thoughtful and informed decision. In this case, is this or that fish suitable for an aquarium, will it be a good "neighbor", do they generally comply with all compatibility parameters.

Fish compatibility options:

Experts carefully studied the behavior and habits of fish. The analysis revealed the reasons why a certain type of fish may not be suitable for a particular aquarium. This means that the fish is too large for this tank or in comparison with the other fish living in this water "dwelling". Even if a large fish does not eat small ones, the younger brothers will feel uncomfortable. Scientificly speaking, the compatibility of fish in an aquarium is a rather thin area that does not tolerate trifles.

Fish should not be too small compared to other fish, as they can simply eat it. There are species of fish that require more territory than usual. For example, a parrot loves space. Paying attention to the compatibility of aquarium fish, you need to know the behavior of predatory fish. Some by nature eat other smaller ones. In their native element, their habitual habitat, such behavior is characteristic of the representative of the aquatic world who feed on fish. Many omnivorous individuals also eat other fish, smaller than themselves.

It so happens that the fish bites off other people's fins. Most often, this trend is observed if there are fish with long, bright fins in the aquarium. Or, on the contrary, the fish itself has a “unique image”, which is a temptation for some fish who have a habit of biting other people's fins. To study these points helps the table of compatibility of aquarium fish. These data will give important information about the behavior and character of the fish.

Aquarium fish compatibility chart

There are individuals that eat aquatic plants, and some are simply buried in the ground, thus the fish will constantly dig up plants. Studying the compatibility of fish in an aquarium, you should be aware of environmental factors:

  • chemical composition of water
  • lighting,
  • its movement and temperature
  • shelter

All the nuances of habitat conditions of underwater pets matter and should be considered in general connection. Therefore, the compatibility table will help you find the perfect neighbors. Also such aggregated data will provide additional information about fish life.

Fish living in groups

Special attention should be paid to representatives of fish species that live in flocks in their usual habitats. Therefore, they will not tolerate loneliness, since the desire to gather in the doorposts at their genetic level. In nature, this is their way of protection from the predator. Some species of bottom fish, for example, the corridor and some loachworm, live in groups. And of course, here we are not talking about the compatibility of aquarium fish, but creating the conditions for their existence.

Compatibility of aquarium fish. Table. Features of the calculations

When choosing an aquarium, each of us first of all thinks about how much to choose in order to provide decent conditions for the existence of fish in it, as well as which types of them can be kept together, i.e. combined. After all, the compatibility of aquarium fish, the table of which will be presented below, is the most important thing when breeding them. This is the ability of two or more different types to interact with each other without prejudice to their growth and development. This quality will be discussed further.

Where to start

A beginner who has just begun to engage in such a difficult task as breeding aquarium fish should think about trying to buy an aquarium of a small or even minimal size and buy those species that are unpretentious in care.

It is best to populate the aquarium first with some one type of fish, for example, cockerels, gourami, cyclides, or guppies. However, even about them you should read the special literature in order to know the individual characteristics when growing each individual.

Such tactics will help gain first experience and reduce the risk of failure to a minimum. It should be taken into account that in this case it will also be necessary to monitor the optimal readings of the water temperature and its chemical characteristics, replace the fluid in the prescribed manner, and also purchase a filter for air supply and cleaning the aquarium. In general, there will be a lot of trouble until the whole process becomes a habit.

After the basics are mastered, the fish are healthy, and the water in the aquarium will be optimal for their life, you can begin breeding various types of these amazingly beautiful living creatures, taking as a basis the compatibility of aquarium fish, tables and information of professionals.

How to populate the aquarium

For ease of understanding and ease of reading is usually when considering such a thing as compatibility of aquarium fish, the table better helps to understand all the difficulties.

Fully compatibleLimited compatibility

Not all beginning aquarists understand that in their behavior some fish can be calm and peaceful, while others, on the contrary, can be militant fighters for their territory. In addition, there are species belonging to the category of predators, and they can simply eat their peace-loving neighbors, which will bring a lot of chagrin.

For example, if we consider the compatibility of aquarium fish (a table for the most common species is presented above), it can be understood that piranha and electric eel can easily “kill” all inhabitants of the aquarium, they can even confuse the owner with food, which is extremely unpleasant. Quiet guppies will not live long in the same territory with aggressive and warlike cichlids. Goldfish cannot exist with danios, gurus and scalar, etc.

The reasons for the incompatibility of aquarium fish

In addition to the above classifications of aquarium fish, you should also mention other possible causes of incompatibility, such as:

  • the size of the fish (the larger its size and the possibility of growth, the greater the volume for its life is required);

  • the optimal amount of water for one individual (can vary greatly depending on the species);

  • large difference in the size of aquatic inhabitants (leading to eating small fish sizes);

  • the presence of bright fins (can lead to eating them by other neighbors).

To minimize the risk of death of aquarium inhabitants, it is necessary to make a preliminary calculation of fish compatibility, which will make their existence comfortable and reproduction possible.

Classification of aquarium fish compatibility

As already mentioned, each type of fish needs special care. Nothing is said about this in the tables, because the aquarium species compatibility table divides them into three broad categories: fully compatible, totally incompatible, and limited compatible. It contains general data and does not take into account important details.

Features care for aquarium fish

one.Large fish are more demanding to care, they live longer, grow gradually, and their oxygen requirements, food is also directly proportional to the increase in their size.

2. Small fishes are less whimsical, but they, as a rule, can exist only in groups, die alone.

3. Viviparous fishes easily adapt to new conditions, freely breed in any aquarium, but require careful supervision of the fry, which should be evicted in time so that they are not eaten.

Thus, when studying such an indicator as compatibility of aquarium fish, the table helps to understand the most important thing - is it possible to colonize these species together? However, this information is not enough to make the final decision, so a novice aquarist still needs to calculate compatibility and read additional information in order to find out as much as possible the individual characteristics of each individual and provide it with comfortable conditions for growth, development and reproduction. Only after such preliminary hard work can we be sure that the aquatic inhabitants of the aquarium will be good in it.

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

Thorns is a small, popular dark silver fish. It can be found in any pet store and in many home aquarium. Its unpretentious content, ease of breeding, peaceful nature - deserves the attention of aquarists beginners.

Latin name: Gymnocorymbus ternetzi

Synonyms: Black, mourning

In English: Black skirt tetra, Black Widow tetra, Black tetra.

Order, family: Characteristic.

Comfortable water temperature: 21 - 24 p.

"Acidity" Ph: 5,7 - 7,0.

Rigidity: up to 6-16 °.

Aggressiveness: not aggressive 20%.

The complexity of the content: easy

Compatibility: The terntions calmly get along with all non-large and non-aggressive fish, such as: gourami, scalars, large tetras, sword-bearers, danios, corrido-dogs, sac-haired catfish and others.

Not compatible: It is not recommended to take them to the "veil" fish, slow and frankly small fish. It is not recommended to contain them with neons, guppies and other bipod. At the same time, the terntions are not compatible with large and territorial cichlids: tsikhlazomy, astronotus, with other predatory fish. It is noticed that when keeping a terence in a flock, they can bite each other. See article compatibility of aquarium fish.

How many live: Life by aquarium standards is short-lasting, with good conditions of detention can live up to 6 years. On average, live 3-4 years. Find out how much other fish live HERE!

The minimum volume of the aquarium: Thorns can be maintained even in an aquarium from 10 liters, in such an aquarium you can put 1 well, a maximum of two fish. However, they are schooling fish and therefore it is better to keep them in a group of 35 liters in a tank. 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).

Care requirements and ternation conditions

Fish do not need supernatural conditions of detention. Observance of optimal parameters of aquarium water is the key to their well-being. However, it is worth remembering that:

- necessarily need aeration and filtration, weekly substitution of up to 1/4 of the volume of aquarium water. If you change the water to them less often than once a week, nothing terrible will happen, the fish are hardy and adapt to any conditions. And if you have a large aquarium, then the water for terntion can be changed once a month.

- the fish need free space for swimming, if you have a small aquarium, it is better not to densely populate it with plants and select swimming areas.

- Aquarium decoration, can be anything: snags, stones, grottoes and other decorations. But since the fishes have a dark color, it is better to decorate the back wall of the aquarium with a lighter background, the ground is also not black. Shelters (grottoes, caves) are absolutely unnecessary for ternations, sometimes they hide only in the thickets of plants.

Feeding and diet ternii

Omnivorous - not whimsical in food, not prone to overeating. With pleasure they eat live, dry food, substitutes. Live and frozen food (bloodworm, artemia, daphnia, etc.) - adore. Food is taken by fish mainly in the middle layer of water. Fallen to the bottom of the food will also be eaten.

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.

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, live:

Area - Brazil, Bolivia: the river Mato Grosso, Rio Paraguay, Rio Negro. They live in ponds with dense vegetation, which is why, if the home aquarium allows, it is better to decorate it with live aquarium plants, and in the center to provide an area for free swimming.


The body of the termination is flat, the color is silver-striped - 3 black stripes are located across the body. One of the bands passes through the eye. Fins, except anal - transparent. Anal fin - black fan-shaped. The length of the terns is 4–5 cm. The females are larger and wider than the males, with a fuller abdomen.

Fish energetic, mobile, schooling. Shy of fear, they can turn pale and hide in a secluded place.

Varieties of terntions

In addition to the terns with a natural color - silver-black, in my lifetime I met a selection veil shape and color variants of gold (white) and pink (caramel) ternets. Here they are in the photo.

Veil Throne Gold Thistle

Pink thorns

And of course, the well-known trend of Glo-fish has not bypassed these fish for many.

Glofish - These are genetically modified fluorescent fish.

The first fish that have been mutated is Danio rerio. As a result of experiments received fish with red, green and orange fluorescent color, which becomes brighter and more intense with ultraviolet light.

In 2011 genome-modified ternation was derived

A bit of history:

Europe, thorns appeared in 1933, and were introduced to Russia in 1946.

Described by the Belgian-British zoologist and ichthyologist George Albert Boulinger (Boulenger) in 1895.

Cultivation, reproduction of a ternation

An important point in the propagation of termination is the selection of producers. They can only be individuals maturity - 8 months and the size of 3-5 cm. All other small or too large in the producers are not suitable.

A spawning 40 liter aquarium is settled as follows: moss-like plants are laid out on the bottom: key moss, Javanese, stump, etc. Fill the aquarium with fresh water at 5 cm. The temperature of the water is maintained at 24-26 ° C. Good aeration is desirable.

On the third day, when the water is infused and becomes absolutely transparent. Manufacturers are planted in the spawning aquarium and begin to feed them abundantly with live food. At the same time there should be no residues.

At 3-6 days spawning occurs. The male begins to chase the female throughout the spawning game and at the moments of a short-term stop the female sweeps up to 30 eggs one-time, which are immediately poured with milt. Spawning lasts about 3 hours. The number of eggs for one spawning is about 1000 pieces.

After spawning, the producers are immediately removed from the spawning aquarium, otherwise the roe will be eaten.

The incubation period for caviar is about one day. During this period it is necessary to raise the temperature of the aquarium water to 28 ° C.

The larva of thorns is small, barely noticeable. At first it hangs on the plants and the walls of the aquarium, and the 3rd day begins to swim.

Juveniles are fed standardly grated live food, live dust.

In the process of growth, the fish are sorted, small and defective are destroyed.

See more details The breeding forum: what caviar, larvae, care feeding fry and so on.

Diseases of termination.

It is very stable fish and can tolerate harsh conditions of detention. But you should not experiment. The guarantee of absolute health is proper maintenance.

Terrestitia is susceptible to all typical diseases of aquarium fish and there are no nuances in their treatment. They are treated standardly: by raising the temperature to 30 degrees, by methylene blue, tripaflavin, baths with salt, etc.

For correct and correct treatment, it is necessary to diagnose the disease, and then apply the necessary procedures. This section will help you: Aqua medicine, fish diseases.

These fish will not deliberately disturb their neighbors, chase and eat their fry, as they eat only small food. Females often hide in shelters or dense vegetation, sometimes they swim up to the upper layers of water in order to get air from the surface. In males, the character is unpredictable, sometimes flimsy and aggressive, but they are poorly protected from predatory species, if there are such in the aquarium. They are easy to grab for thin thread-like fins of the abdominal part.

It is important that they live well with other fish, their character unpretentious and peaceful. If you want to save them a prosperous life, take care of good-neighborly settlement.

Are compatible with each other?

Interspecific differences arise between them, during which they clarify the hierarchical roles or protect the territory. Aquarium gourami are practically incompatible with other members of their family. Naturally, when representatives of one species get along, but this does not apply to this species. Here everything is much more complicated. They constantly vie for the attention of the females, if there are few females in the aquarium for the male, he will not create a pair.

See how they fight gourami.

The fight between males can be extremely dangerous and lead to strong aggression, even worse than the attack of fish of another species. Compatibility is possible if one male and 2-3 females are placed in the tank for him. Then all the inhabitants will remain unharmed and happy. The labyrinth fins are usually thin and long, so they are easy to capture during rivalry.

Compatibility with other species

Aquarium gouras can live with other fish even better than with their closest congeners. Compatibility is possible with peaceful small fish that will swim in the middle and lower layers of water. There are also a number of representatives of the underwater world, with whom the gurus easily get along. Compatibility is possible with neons, iris, danios, battles, swordtails, tetras, catfish, minors. Representatives of the families of cichlids and scalar also get along with gourami.

It is not recommended to settle with large predators, with fast and active fish, playful. This applies to species that can pluck fins and constantly interfere, among them: barbs, cichlids, roosters, parrots fish, astronotus, goldfish.

Compatibility is not possible with discus, shrimp, guppy, since there will be a confrontation between them, or some will be eaten by others.

The following factors may cause conflicts between gouras and unrelated fish species:

  • Bright color or long, fluffy fins that attract caring neighbors. They can tear off the fins, or destroy the "handsome";
  • Disproportionate fish need space for swimming and life, if some fish swim at the upper layers, others at the bottom, this does not lead to collisions;
  • Insufficient aquarium volume and lack of personal swimming space, insufficient number of plants and shelters;
  • The main cause of conflict is the appearance of superiority in size, large aquarium fish immediately notice small fish, perceiving them for food.

Look at the aquarium with gourami, scalar and speckled catfish.

Compatibility criteria

To understand whether compatibility between species is possible, it is necessary to become familiar with the criteria of full, partial compatibility and incompatibility. With full compatibility, you can safely observe the life of fish, with partial threats of rivalry, in the absence of compatibility as such, fish do not need to be placed in one aquarium at all.

Barbus-care breeding description compatibility photo video


Black Barbus - a common aquarium fish. It was first imported to Russia in 1954. Pethia nigrofasciatus is not large. By its behavior, the shape of the body resembles the barb of Sumatran. Habitat Black barb is naturally found in Sri Lanka, most commonly found in tributaries of the Nival and Kelani rivers. They are distinguished by an abundance of vegetation, a weak current and cooler water than in other tropical waters. Here it is sour and soft, and the bottom covers fine gravel or sand. Algae and detritus - the basis of the barb diet in nature.

Currently, the population of this fish has decreased significantly. This is due to the overfishing of the black barboo.withand for aquarists. For a time, the species was considered endangered, but in recent years the population has increased slightly. Currently, it is prohibited to legally catch a black barb, therefore all individuals found on sale are artificially bred. With the help of hybridization today, brighter, newer colors of black barb are being created.


Water parameters. The temperature range for the Sumatrans is quite large - 23-26 ° C, they prefer soft and very clean water. A good filter is the key to the health of your pets.

Lighting. This fish has no special requirements for lighting, Sumatran barbus is generally distinguished by a rare unpretentiousness (what other underwater inhabitants are easy to maintain

Aeration. The sensitivity to the oxygen content in water of the Sumatran barb is extremely low. However, it is not necessary to bring the matter to the point when the fish will float on the surface head up, it is better to periodically replace some of the water,

if there is no forced aeration in the aquarium.

Barbs fishes: breeding

If there is a desire to start breeding barbs, then you need to start with the selection of the ideal breeding fish. They must be mature, healthy and without physical abnormalities. Selected manufacturers should be in special conditions of detention. The list of these conditions begins with two main points - a spacious aquarium and high-quality food. For a decade before the breeding season, females and males are deposited separately and properly fed. A spawning aquarium is absolutely not needed too large, as it will often need to change the water. Twenty-liter volume is enough.

In the mating season, fish emit a huge amount of sexual products. Males should be placed near females 2 hours before switching off the lighting for the night. It often happens that in the morning you can already notice the results of spawning. It is difficult to see caviar, it is very small and transparent. But you should try to see it, because when the eggs appear, the fish should immediately be deposited, otherwise they will simply eat their unborn offspring, having decided that this is food.

If it was not possible to make out, look at the behavior of potential parents, if the “date” was successful, the male and the female lose interest in each other and are each engaged in their own affairs. It happens that the caviar is dead, this can be determined by the color change of the eggs. After some time they will become white.From live roe the next day a larva will appear, which will attach to the walls of the aquarium or to the leaves of algae. After waiting for the fry to swim, you can feed them.


Barbus compatibility with other fish

This fish does not have a reputation for threatening an aquarium, however, short-term flashes of aggression still occur both in a flock of barbs and in bar’s relations with neighbors of other breeds. You must be prepared for the fact that quarrels between these creatures sometimes become so acute that the fish begin to destroy each other! Veiltails, guppies, cockerels, scalars and telescopes are best to stay away from the barb in a bad mood, otherwise they may lose their voile tails and fins.

Do not expect anything good from the neighborhood brisk barbs and fearful passive lyalius. And the bullying astronotus bar is not a couple, because the fish will certainly want to measure themselves.

Of course, the barbs would not have refused to become the sole and full owners of the underwater territory, but if you plan to breed several types of fish in one aquarium, the World of Soviets recommends to add barley, parrots or mollies to barbs. Fish with a similar disposition and lifestyle will surely get along.

Rod barbus (Puntius) - one of the most common genera of aquarium fish. It is remarkable that its representatives are not capricious, have a bright and varied color, are very active and mobile. Unpretentiousness attract the attention of novice aquarists.

Hailing barbs from the reservoirs of China, Africa, Southeast Asia. In the wild, fish of the genus Barbus live in flocks, and moreover very large ones. The maintenance of barbs does not represent special difficulties. Chemical parameters of water (hardness, acidity) do not play a special role. Water barbs prefer the old, with the traditional replacement of 1/3. Temperature range from 20 grams. Up to 26. But the temperature is still desirable 23-26 gr.

The shape of the aquarium is chosen taking into account the fact that the barbs are very fast and fast-moving fish. Aquariums for barbs usually have an elongated, elongated shape, so that the frisky fish have a place to “gain acceleration”. The ground in such aquariums is usually dark, and the lighting is bright. Such a contrast favorably emphasizes the color barbs. Floating plants create extra space for fish "maneuver."

Two mandatory conditions for the breeding and maintenance of barbs - powerful filtration and aeration of water. Also for the barbs you need to purchase a pump. The pump is needed to create a flow imitation. Underwater currents - a kind of "toys" for barbs, fish love to frolic in the jets created by additional equipment.

In the aquarium barbs live in flocks (5-7 pcs.). With good care they will please you 3-4 years. For all their friendliness and livability, the barbs are sometimes snooty. They are particularly addicted to sluggish guppies with flowing tails.

The favorite occupation of the barbs is to sneak up on the tails of the tails and bite their fins. Magnificent fins annoy the barbs: occupy a lot of space in the already limited water space. It is possible that the modestly decorated barbs of nature are slightly envious of their overdressed counterparts. Undemanding barbs are undemanding in everything, including food: they are omnivorous. With a food deficiency, barbs are happily reinforced by leaves of aquarium plants.

Appearance of fish and varieties

The average size of adult barbs is a maximum of 6-7 cm. The slightly flat yellow-silver body is decorated with dark vertical stripes. The male has a bright red border around the edges of the dorsal, caudal, and anal fin.

Slightly less expressive, also in red (sometimes this color may be completely absent), the fins of the female are painted. In addition, the self-made barbus is significantly thicker than the male.

If we talk about breeding, it allowed aquarists to gain a wide range of color variations of this fish. For example, in a mutant barbus obtained in this way, the color of most of the body is emerald green.

Visiting pet stores and markets of Russian cities, you can most often meet the following types of barbus:

Barbed bar (otherwise, striped). The fish of this species is uncharacteristically large in size - it can reach 9 cm. Its stripes are arranged horizontally, capturing the entire length of the body.

Barbus Everett. Remarkable are the inhabitants of the home pond for their non-standard color with black and blue specks over the entire area of ​​the body.

Oligolepis. This species is attractive pearl scales and red fins with dark edging. In addition, depending on the angle of incidence of lighting, the color of the fish changes.

Five-bar. The name of the fish itself indicates its difference - this aquatic inhabitant has five transverse bands on the body.

Green barb. Like a lined representative of a species, it has a large size (up to 10 cm) and its body has a corresponding color.

Ruby fish barbus. The unique ruby ​​color of the pet, acquired by him during the mating games, is his main distinguishing feature.

Who do the barbs get along with?

Barbus - killing fish, representatives of the genus Barbusov. Natural habitat - Africa and Southeast Asia. There are several dozen species of these fish that lead the pack way of life. The average size of small fish is 4-8 cm. Sometimes, endemics caught in natural water bodies can be seen on the market, and they are easily adapted to the home aquarium. Some adults grow large, 12 cm or more in size.

The opinion is widespread, their compatibility in an artificial reservoir is possible with other fishes. Indeed, some aquarists are not afraid to settle them with gourami, guppies, swordtails, and even cichlids. However, the school of barbs is able to intimidate and show aggression towards neighbors, sometimes destroying them physically. Yes, and among themselves they get along not without resistance - these fish are active, nimble and will not miss theirs.

Fish behavior

Barbs growing in length of 10-12 cm are classified as large species. Among them: arulius, Everett, red-cheeked barb, African barbs. Compatibility in the general aquarium is possible with cichlids, freshwater sharks and catfish. Medium and small barbs reach a length of 5-6 cm in the aquarium. These include Sumatran, five-lane, green, ruled, oligolepis barb.

They are united by a cheerful disposition and a high level of activity in the water, so they are recommended for breeding in glass tanks. Get on with other fish of similar size, but not with slow. Snooty character - fish with long and veiled fins pluck, depriving those of a beautiful appearance. For them it is better to choose a spacious rectangular aquarium, where there will be enough space for swimming. Shelters are also important - stones, snags and plants, but in a certain amount - they are not needed much for schooling fish. 6-7 fish should be acquired immediately to avoid stress and conflict situations.

Look at the aquarium with Sumatran barbs in the company with scalar scalar and ordinary.

A signal of unfavorable conditions in an aquarium may indicate a strange position of the fish - when they do not lie at an angle of 45 degrees head down (as during rest), but at a greater angle.

Quickly swim in the pond, are constantly in motion, play among themselves, catch up with each other. They live not very peacefully, they will compete with even aggressive species of fish. Therefore, it is necessary to carefully and carefully choose their neighbors.

Who can live with most barbs?

Before allowing other fish to approach them, it is necessary to check their compatibility in the aquarium. As you know, these teasers are not averse to fighting or pinching their neighbors, it may be fun for them, but for others it is a big fright.

To oppose the barbs, the fish have to gather in large flocks, and the nature of these "competitors" must be strong, not fearful. Only under such conditions can provocations be avoided. Often, barbs of different types are settled in one nursery, so as not to risk unsuccessful sharing.

If you want to pick up the fish on the similarity of color and temperament, avoid the neighborhood with slow-moving fish. For example, Sumatran barbs look good with clown fights - they have a similar scale color and similar habitat.

Proven compatibility between barbs and other species of fish with which they live peacefully, these are small fish:

  • The Swordsmen;
  • Clowns;
  • Botsia;
  • Pecillia;
  • Gourami;
  • Labeo.

On the behavior of Sumatran barb with neighbors

Sumatran barbs, or tiger - very mobile representatives of the underwater world. Make a perfect neighborhood in the aquarium to those fish that have an active disposition and similar sizes. Compatibility with fish, in which wide void-shaped fins are unacceptable - they bite them. Fish of medium and large sizes are also not always suitable. Gourami, cichlids, telescopes, scalars, and tails are incompatible with them. Restless appetite "tiger" will create problems for a peaceful fish, taking away her food.

Fish that have offspring, will also suffer - their fry will be eaten by the Sumatran "tiger." Even the fish from their flock, they oppress that already talk about strangers. This is a territorial view that considers itself the owner of the reservoir. If the fish has mastered some part of the aquarium, it will not give it to anyone - the enemy will be immediately expelled.

Tiger barbs can not be called very aggressive fish. The described cases are rare, and, as a rule, under the wrong conditions of detention and sharing. They are recommended to be settled in the pond after other fish live there and get comfortable - in this case mutual sympathy and respect for each other will arise.

Is it possible to move the barbs to live-bearing fish?

Fishes of different types require a large space for keeping. When flocks of different species of fish are found in a small aquarium, territorial and personal conflicts begin. Big mistake novice aquarists - sharing the barbs to the peaceful viviparous fish in a small tank.

Look at the Sumatran barbs along with the green labo.

Guppies do not belong to those types of fish that can be hooked to active fish. There were cases when the latter attacked guppies, even an increase in the number of males did not help. We have to settle these species in separate nurseries, saving them life and health.

Do the barbs go up to the swordtails?

Swordtails have large and lush fins, to which the barbs are not indifferent. A big plus of the Sword-bearers is high mobility and activity in the reservoir. A chase may occur, and the barbs will surrender. But in order for the neighborhood to be successful, you should follow several rules:

  1. Do not keep too small aquarium: there should be enough space for everyone in it, be sure to plant water plants in it. Large space will allow barbs to frolic.
  2. Move to the swordtail barbs of different types. This is to prevent aggression. Representatives of different species will begin to sort things out among themselves, without disturbing other fish.
  3. Barbs have no sense of proportion - having bitten a fish once, a predator wakes up in them. They will not lag behind the victim, and may ultimately destroy the creature. This happens when the supposedly active swordtail is calm and slow.
  4. Swordtails will not show aggression to the barbs, if they will have enough food and shelter. Subject to the rules, all fish can cohabit peacefully and without conflict.

More about compatibility

If you have a beautiful and spacious aquarium with gourami, and you decide to share a flock of barbs with them - be careful! The latter are avid hooligans who will literally “get” beautiful fish. Gourami will calmly relate to such a neighborhood, but one cannot say so about barbs. Small species get along with gourami, but large ones can damage their fins, and even destroy. Again, in order to prevent conflicts, a flock of 6 or more individuals should be hooked up immediately, so that the barbs have a showdown of the relationships within the flock. Gourami will only watch the fights and chases. Given this fact, gourami and barbusyat can be neighbors in the same territory.
