maintenance, care, compatibility
The sword-bearer (Latin Xiphophorus hellerii) is one of the most popular and unpretentious fish in the aquarium.
The first swordtails appeared in aquariums back in 1864, and since then have not lost their popularity. The long outgrowth on the lower fin in males, like a sword, gave it a name.
But not only for this they love the Swordsman – he is unpretentious, handsome, very diverse in color and easily reproduces.
Swordtails in general are quite peaceful fish, well suited for general aquariums. But, they have very different characters, and he can be both a quiet and timid, and a cocky bully.
Especially males can be aggressive towards each other.
Swordtails are best kept in aquariums with lots of plants and free swimming. Floating plants will create diffused light and provide shelter for fry.
Like many live beetles, swordtails can live in brackish water, but this is not necessary.
You can feed them with cereal, live or frozen food, and other feed for aquarium fish. Like all fish, swordtails need a varied diet. It is especially important to feed them with plant foods that are high in fiber.
The fact is that in nature, thin and fragile algae constitute a large part of the diet of the Swordsmen and other fouling. In an aquarium, this amount of algae will be superfluous, but you can always buy flakes with a plant component.
You can make these flakes the basis of the diet, and live food additional nutrition. Live food can be given any, swordtails completely unpretentious.
Aquarium fish swordtails: reproduction and maintenance
Aquarium fish swordtails: compatibility with other species
These are, in general, fairly calm fish; they only sort out relationships with each other, so you can keep them in the same container with other species. The only thing that they can aggressively treat smaller fish.
Barbs, cockerels, discus, tetra, labo, guppy, gourami get along well with swordtails.
Not very successful combination with them are eels and shrimps, but cichlids, goldfish and astronotuses are completely incompatible with swordtails.
The compatibility of aquarium fish is a burning issue that many aquarists have. And it does not matter who you are – a novice aquarist or already experienced, when deciding whether to populate an aquarium, you automatically have passing experiences about the compatibility and compatibility of the fish with each other.
The compatibility of aquarium fish is a vast subject, controversial, purely individual for everyone. Therefore, around it there is a lot of debate, controversy and controversy.
Well, let us try to systematize this question in this article and how to fully disclose it!
First, let’s look at the basic rules for selecting aquarium fish.
– When choosing aquarium fish in the first place take into account their compatibility.
– eat fish not compatible together;
– eat fish relatively compatible;
– eat completely compatible;
– Choosing a specific type of aquarium fish in a pet store, evaluate their health status (fish should not be lethargic, pale, etc.)
Assess the degree of aggressiveness of a specific fish (even if this type of fish is peaceful, sometimes overly aggressive types are encountered, for example, this behavior is often found in gays of blue).
– When buying fish, consider their features and intraspecific aggression.
For example, for “harem” fish, one mate needs to take a pair of females and vice versa for such fish as danios or barbs you need to take a flock, in which males will prevail.
Fish swim in different layers of water: someone in the lower layer, someone on average, and someone at the top.
So that your aquarium does not look empty, select fish living in different layers of water.
– When choosing and buying fish, be sure to consider the comfortable parameters of water for their maintenance. It is impossible to combine the fish with different requirements – one will be hot and the other cold, one needs soft water, and the other, on the contrary, harder.
– As a general rule, it is recommended to keep large fish with large, slow-moving with slow-moving, nimble and nimble.
– If there are “herbivorous” fish in your tank, consider this when buying plants. In this case, it is better to acquire artificial plants or hard-leaved plants, and the fish themselves to buy inexpensive plant species or breed duckweed.
-There is one more rule! If the fish are relatively compatible, and you really really want “both this and that.”
Consider that it is best to buy and plant such fish in the aquarium at the same time with young (fry). In this case, the fish, though not very friendly to each other, but as they say they can “get used to.”
I do not think that the above rules sparkle with innovation, but as a starting point in the discussion of compatibility of fish there are places to be.
Now let’s get straight to the issue of compatibility. As already mentioned, the fish can be divided into:
1. Compatible with each other;
2. Not compatible;
3. And relatively compatible.
With the first two points, everything is clear – the Goldfish family or neons will not last long with cichlids, or, for example, astronotuses perceive guppies and other small fish as live food. Conversely, guppies are friends with mollies and patzilia.
Full compatibility or incompatibility of fish due to the following features:
– family, squad, suborder of fish;
– parameters of aquarium water and conditions of the fish;
That is, if you combine in the aquarium fish from one family or about the same size, or with identical conditions of detention – then this will guarantee success! FOR THE EXCLUSION OF ONE, BUT.
Each rule has its exceptions.
I will give an example. Guppies and swordtails belong to the family of petsilians – viviparous fish, they are about the same size (almost, that is, those and those are not large fish. Swordbirds, of course, will be more than guppies) and the conditions of their contents are virtually identical.
It would seem that the fish are absolutely compatible with each other. However, it is not. Despite the absolute similarity of the fish on the above criteria, skirmishes and fights can occur between them, swordtails can drive and bite the guppy’s tail fins.
Moreover, in this and the other species, intraspecific aggression is observed, which also adversely affects their joint content in the general aquarium.
At the same time, the Sword-bearers, the live-bearers and the scalar, are South American cichlids, who live peacefully together. Moreover, they look very beautiful together, especially if the swordtails are red, and the scalars are black, voile ones.
Fish of different families, of different sizes, however, are absolutely compatible with each other.
In the photo is an aquarium, clearly confirming the compatibility of the Sword and Angelfish
Based on the foregoing, you can not take for granted and pick up the fish, dividing them only by: size, type and conditions of detention. It is fundamentally wrong to group fish in a similar way and to say that fish from a certain group are absolutely compatible with each other.
In other words, 100% guarantee of compatibility of purchased fish, nobody will give you, there are always nuances and features that you better know yourself and in advance.
In my opinion, a more interesting question is related to the relative compatibility of fish. Since it fully reveals the lit question and gives rise to reflection and discussion.
Often, such compatibility is possible in pp 4, 6 and 8 of the Rules indicated above, adhering to which, it is possible to achieve sometimes the striking “combination of incompatible”.
To give a clear concept of relative compatibility, I will give an example from personal experience. Not so long ago, an article on Ternition was updated on our website, where it was stated that they are compatible with Bagging Som.
When the article was ready and released on the “air”, I turned to the expert of our website for fish breeding – Vitaly Chernyavsky with a request to review the article. So, as a comment to the article, Vitaly expressed his opinion that the Ternetsia and Bagniferous soma are not compatible, since the latter are terrible aggressors and predators. To which I objected in surprise – as so, because in my aquarium the thorns have been swimming for a long time with two bag-tailed catfish and everything is fine between them.
Our discussion is at a standstill, because the arguments that the expert cited did not correspond to the real situation in my aquarium.
The time has passed, and somehow, on the Internet, I was caught by the book of I.I. Sheremetyeva “Aquarium fish”, 1989, where the author describes the natural habitat and behavior of fish in natural conditions. When I began to read a section of the book on the bag-wading catfish, my hair became on end.
It turns out that these catfish are not just predators, but “fierce killers”. In their homeland, in Asia, they exterminate all the fish that are in their reservoir, and when there is no one left, they crawl out onto dry land and crawl to the nearest new reservoir for the “new victim”, while at the same time eating on land »Insects and small frogs.
It turns out that Vitaly Chernyavsky was right, bag-haired catfish are really fierce beasts.
The most important paradox is that, along with thorns in my aquarium, along with catfish “killers”, for six months I calmly swim the most innocent live-bearers, Radishes. Who does not believe, here is a photo.
THERE’S SO, THAT IS THE SAME VILLAGE OF FISH AND IS CALLED RELATIVE COMPATIBILITY How to achieve this? Well, firstly, do not go too far, secondly, clearly adhere to the previously stated rules, well, and third, perhaps the most important – you need to have experience, read and treat your pets and the aquarium as a whole in good faith. To reveal the individual compatibility of a specific aquarium fish is very difficult.
To do this, you need to write a separate article for each type and at the same time take into account specific conditions of detention Therefore, if you have any questions, I OFFER TO DISCUSS THEM IN THE COMMENTS TO THE ARTICLE.
Summing up the article to a logical conclusion, I would like to finally draw the reader’s attention to the mistakes that aquarists make when combining fish.
The first and perhaps the most blatant violation of the compatibility of fish – is the overgrowth of the aquarium. Each aquarium pet should live in a comfortable environment, and not in the “communal”.
Overpopulation of aquarium is a direct path to fights, injuries and death of any fish, even peaceful ones.
Second violation – This is not compliance with the conditions of detention and zoning of the aquarium. Containing fish, you need to take into account their specifics, their characteristics and character.
For example, you can not contain wyunov akvantoftalmusov in an aquarium with coarse-grained soil. Aquantophthalmos are bottom-dwelling and love to dig in the ground, therefore sand or small pebbles are suitable as a substrate.
On a large soil, they will “fight like asphalt”, may be injured and die.
Zoning is to divide the aquarium into zones of influence. For example, in order to prevent scalar fights among themselves, it is recommended for each individual to zone an aquarium with plants – vallisneria.
And the third violation. Always remember that “We are responsible for those who have tamed.” Improper maintenance of fish leads to dismal consequences.
In bad conditions, the fish begin to fight for survival, fight and die.
Below is a table of compatibility of aquarium fish. She is often criticized by aquarists, however, as a guide she can serve well
Below are all other aquarium fish compatibility charts.
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.
Swordtails have large and lush fins, to which the barbs are not indifferent. A big plus of the swordmen 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:
- 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.
- 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.
- 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.
- 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.
Representatives of the Macropod family in the aquarium reach small or medium sizes. Most often they compete with each other, so they need to be settled with other types of fish, such as: angelfish, barbs, corridors, danios, battles, mollies, petilles, plexostomy, iris, rasbor, labo, swordtails, tetra.
Incompatible with cichlids, males, goldfish, koi carps, astronotus.
Fishes of the Vynovye family, schooling. Not bad get along with other aquatic organisms, if there is enough space for habitat and the presence of shelters. Compatible with the representatives of the underwater world:
- By incentives;
- Sword bearers;
Neighborhood is not allowed with representatives of such species: astronotus, cichlid, koi carp, goldfish.
The family Melanotene (Iris) has seven genera, which include small but very beautiful fish with shimmering scales. Absolutely innocuous creatures, do not attack others, but rather become victims of large fish.
In an aquarium, it can be cichlids, astronotus, koi carps and goldfish. With other neighbors get along well.
Fish squad kartozubye, bright color and original appearance. Just get along with all the peaceful fish, except for large cichlids and carps.
Peace-loving, small fishes of the Kharatsin family. Movable and harmless.
Compatible with peaceful hydrobionts, except cyprinids and cichlids.
- The main mistake is overpopulation of the reservoir. In cramped, but offended! Pisces do not understand what it means to give in to another; they inherited from their ancestors a tendency to fight for survival. A small territory, a lot of fellows, which means that there is not enough food for everyone. Therefore, it is not surprising if there were fights in a small nursery, and other traumatic cases.
- Incorrect zoning aquascap. Carefully read the rules of settlement of each pet: what plants are allowed, the substrate, the parameters of water.
- The content of large and small fish. Even a peaceful large cichlid can eat a small neighbor if it fits in her mouth.
- Ignoring the rules of spawning. During this period, the fish are more aggressive and sensitive. If they spawn in the general aquarium, they will be greatly disturbed, or they will eat eggs with fry. In order to avoid such cases, temporarily transfer the male and female to a separate spawn with acceptable conditions for reproduction.
- Wrong conditions of detention, when pets instead of pleasing the eye, gradually fade. Regular water changes, cleaning the tank, properly feeding – a guarantee of their health and a quiet life without conflict.

Small ray-finned fish of the carp family, small size. Have a peaceful nature. You can keep in a general aquarium with cockerels, scalars, barbs, corridors, guppies, gourami, battles, minesies, patsilii, plecostomus, iris, rassetami, labo, swordtails, tetras.
You can not settle with cichlids, discus, goldfish, astronotus, koi carps.
Look at the zebrafish and pink angelfish in the same aquarium.
Very beautiful, bright aquarium fish. Have a peaceful nature. The table indicates that they are compatible with such neighbors:
- By incentives;
- Sword bearers;
It is forbidden to run into a common reservoir where they live: angelfish, barbs, roosters, cichlids, goldfish, guppies, koi carps, astronotus.
Gourami are small fish of the Macropod family, a suborder Labyrinth fish. Many species are endemics of Southeast Asia, prefer calm waters with a slow current.
Gourami in these regions are of industrial importance, but in many aquariums in the world they are ornamental fish. They have a peaceful and calm character, small body size, to keep them simple even for a beginner aquarist. Gourami practically do not show aggression towards their neighbors in the “house”, most often they are in conflict with each other.
To settle them in a common nursery, you must understand the peculiarities of their character.
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.
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.
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.
Couples gourami and fish compatibility:
- Angelfish and gourami: fully compatible
- Barbus: partially compatible
- Petushki: incompatible
- African cichlids: incompatible
- South American cichlids: incompatible
- Corridors: fully compatible
- Danio: fully compatible
- Discusses: partially compatible
- Lost: Partially compatible
- Goldfish: incompatible
- Gourami: partially
- Guppy: Partially
- Koi carps: incompatible
- Botsii: fully
- Mollies: fully
- Astronotus: incompatible
- Percylia: fully
- Plekostomusy: fully
- The iris: fully
- Rasbory: fully
- Labeo: completely
- Swordsmen: fully
- Tetras: fully
- Acne: Partial
- Piranhas are incompatible
- Shrimp: incompatible
- Floating aquarium plants: fully

Fish that are suitable for settlement with Poecilia reticulata
There are a large number of freshwater aquarium fish that can live with guppies in peace and harmony. The listed types are the safest options.
They mate with these viviparous Pecillians in terms of similarity of living conditions and behavioral characteristics.
Somiki corridor – relatively slow swimmers, almost always in the lower layers of the aquarium. They are characterized by small body size and calm disposition, they gradually clean the aquarium from food debris. Guppies swim in the upper and middle layers of the water, so the corridors will not hook them.
However, one should not add salt to the water in which catfish live (and the pets-liqueras love such water), otherwise they will die.
See how guppies and catfish corridor dwell in the same aquarium.
Indian glass fish, or Malaysian glass – it is often confused with glass catfish, but they are completely different species. The glass is a peaceful and rather hardy fish, they are excellent companions for guppies and other small tropical fish. The transparent body of the body makes them unique, they even shine through the skeleton and internal organs.
Malaysian glass is characterized by gregarious behavior, swims in a group of 5-7 fish. It is not recommended to buy fish with a fluorescent color.
Just “painted” glass fish are more sensitive to the parameters of the aquatic environment, and during the disease color pigment can open wounds, causing infection in the water.
Mollies, patcilia, swordtails – viviparous fish of the Family Petsilievye, which are best compatible with guppies. All fish are related species, in the general aquarium they can breed, bringing hybrid offspring.
Guppies, mollies and platies will not conflict with each other. But the swordtails, especially adult males, can terrorize the tail fish, so it is better to settle with “swords” fish with short fins.
Mollies prefer to live in a pair. If in a spacious aquarium will live a couple of moles and a few guppies, you get a great neighborhood.
Neon tetra – the most popular freshwater and tropical fish. You can keep with any peaceful species of fish, it was even called “pearls of the aquarium.”
Neon tetras are characterized by a rosy blue body with a reddish tinge. They create a strong flock of 6-10 individuals, and calmly swim in the upper and middle layers of water.
Can make an excellent company viviparous fish, without disturbing them.
Rasbory – differ in metallic color scales, they are clearly visible, which simplifies the care of these fish. Hardy, peace-loving, swim in a flock of 6-8 fish.
They can be settled with guppies in the general aquarium, as their characters are perfectly compatible.
Dwarf loaches – like all loaches, they are very peaceful fishes. However, some types of char can grow larger in size compared to guppies.
Dwarf loaches remain small all their life, rarely grow to a length of more than 5 cm, so that they are commensurate with petilia fish. They like to swim in a flock, so settle them immediately with a flock of 3 individuals.
You can build a few shelters in the aquarium, add live plants, because these loaches like to hide and rest.
Endler Guppy (lat. Poecilia wingei) – used to believe that Endler’s viviparous fish are relatives of Poecilia reticulata.
Later it turned out that these are different species, although both come from Central America. There are certain similarities between species; they can interbreed in the same aquarium.
Viviparous endlers are suitable for tropical aquariums, where different viviparous petsilievy live. It should be borne in mind that the Endler fish grows up to 3.8 cm in length, therefore it cannot be accommodated with larger species.
Settle them immediately for 6-8 individuals and more, create shelters for them, otherwise they will be eaten. Poecilia reticulata will ignore them, but under proper conditions of detention.
Observe laliusi, neons, catfish and guppies in the general aquarium.
