maintenance, care, compatibility
– When choosing aquarium fish in the first place take into account their compatibility.
– When buying fish, consider their features and intraspecific aggression.
So that your aquarium does not look empty, select fish living in different layers of water.
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.

So the joyful moment in the life of every aquarist has come – buying fish in an aquarium. The range of fish is very large and diverse. In this article I will try to focus on the basic rules of compatibility of aquarium fish.
What would I pay attention to when buying fish?
Do not rely on the advice of sellers selling in specialized stores. Like any trade worker, it is important for them to sell as many goods as possible at the highest prices.
Before purchasing a fish, you must first make a choice, write down the names of the fish you like, read basic information about your favorites on the content parameters and the behavior of the fish in the aquarium.

Compatibility of fish in terms of content
There are cold-water and warm-water fish, fish that love soft water, and vice versa, hard-water fish. Fish that need thickets of living plants, and fish that tear, dig and eat all the plants in the aquarium.
Many aquarists may argue that they say cold-water blue neons (temperature of 18-22 degrees) live well with the discus, which needs a temperature of 28-30 degrees.
I agree, they live, but with such a high temperature of water in the aquarium, all the life processes of neons are accelerated, their lifespan is reduced, which is already small – only 2-3 years with good conditions, as a result, neons quickly age and die.

Compatible guppies, what other fish get along with them?
Further, softwater fish, such as the American cichlids, will not feel comfortable in hard water. They will live, but be fruitful.
This is in question. I will make a reservation that there are exceptions to the rule: professional avkaryumisty easily breed an angelfish in those cities and regions where very hard water flows from the tap, with a hardness index of 30-35. But such a dilution requires experience and material costs associated with constant water softening (special preparations, for example: Tetra ToruMin, reverse osmosis installation, etc.)
Fish feel very well when an aquarist creates conditions for them that are close to natural. So it was with me when I changed the soil in the form of granite chips, which increased the rigidity of the aquarium water, to neutral soil in an aquarium with discus.
The coloring of these wonderful fish, which are rightly called the Kings of the aquarium, has become brighter, the fish have become more mobile and the most important indicator is the formation of pairs and regular spawning.
Therefore, if you have very hard water flowing from the tap, consider buying hard-water fish, such as African cichlids, platillas, guppies, mollies, swordtails, etc.
Compatibility of fish with live plants. If you want an aquarium with a large number of live plants, then I do not recommend buying goldfish, African cichlids, labo, metinnis, tetragonopteruses, African eels, tilapias, etc.
Some fish perceive plants as food, others like to dig and dig up the soil, thus digging up the plants, damaging the tender roots.
This also applies to catfish, most of whom like to dig in the ground. Ancystrus, in the absence of herbal supplements in the diet, can damage the tender leaves of aquarium plants, filling them with a lack of plant foods.

Compatibility of fish size
The basic rule is this: it is recommended to keep large fish with large ones, and small ones with small ones. Any, even the most peaceful fish, will not miss the opportunity to eat another fish that fits in her mouth.
There is an opinion that if a large fish is planted in the aquarium with fry, then, growing, it will not offend its smaller neighbors. Alas, for me personally, such experiments have not justified themselves.
When a larger individual grew, small fish went to her food.
South American cichlids
Compatibility of fish on the nature of food
This is rarely paid attention, but it would not hurt to take this indicator into account. There are herbivorous and predatory fish.
Features of their power come from the name.
Any herbivorous fish will not give up animal feed, for example, bloodworms.
The peculiarity of herbivorous fish is that they have a small ventricle, the intestines are long, adapted for digesting plant foods.
If such fish are often fed with bloodworms, then over time problems with digestion and liver will begin.
This indicator is especially important to consider when compatibility of cichlids: the majority of African cichlids are animal-eaters, and their combined content with Tanganyki cichlids, trophaus, whose diet is algal fouling and other plant foods is not recommended.
Predatory fish, for example, the African black knife, it is better not to keep in one aquarium with small and peaceful fish. This nocturnal predator will hunt any fish that it can swallow.
From the aquarium with discus, I had to deposit one ancistrus. He, the only one of the three antsistrus living in this aquarium, stuck to the large body of the discus and injured him with a suction mouth.
Such damage can be very dangerous for fish. What was missing in his diet?
Fish scales? riddle. I think this is a feature of his character.
Compatibility of fish on the nature of behavior
This is a big and important topic. A number of fish are very aggressive, especially, aggression is manifested in the period of mating games, spawning and care for offspring.
These fish include almost all tsikhlovye. Most cichlids are large, aggressive (very aggressive during spawning) and predatory fish.
They in no case can not be combined with peaceful, small fish.

Cychlasmas: species, content, compatibility, reproduction
Among the fish there are, for example, barbs, who will not miss the opportunity to tweak another fish at the fins. Therefore, they are not recommended to contain with veil fish that have beautiful and long fins.
Therefore, in the aquarium you need to keep fish of similar nature.
For example, frisky and playful fish danios, it is not appropriate to look next to the majestic discussions and scalars. With their sharp movements, they can scare the discus. Once, I became a witness of how, during a sudden movement around the aquarium, the discus darted in different directions, and one of them, quite noticeably, crashed into the glass of the aquarium, and the other, darted upwards, hitting the aquarium cover.
By the way, this feature of discus, you need to consider when choosing the location of the aquarium. I want to note that my aquarium with discussions is installed in a very busy place of the apartment.
After some time, the fish are accustomed to and do not react to sudden movements.
Selecting fish in an aquarium according to the nature of their behavior, do not forget to take into account such features that many fish like to hide in shelters. It is necessary to ensure the presence of shelters in the aquarium in the form of grottoes and caves. Snags in an aquarium, for example, are important for catfish.
In addition to shelters, snags are part of the diet. For some fish that love to dig in the ground, the fraction of this soil and its processing is important.
For such fish, sand with rounded edges is preferable.
There are a number of other parameters – the demands on lighting, the rate of flow of water in an aquarium: there are fish who love standing bodies of water, and fish that inhabit rivers with a fast current of water, the degree of salinity of water, etc.
I want to note that you can not stick with the choice of fish, only one of the compatibility parameters. You need to take them into account or try to take into account the complex.
Do not forget when choosing fish to take into account the volume of your aquarium and the size of the fish in adult condition. It is important.
To facilitate the adaptation of fish, to new conditions, you can use the preparation, minimizing the stress of fish from transportation and relocation: Tetra AquaSafe, Tetra Vital, Tetra EasyBalance, Tetra Nitrate Minus.
In any case, the choice is always yours, this is your experience.
Most importantly, if you try to take into account the peculiarities of the content and behavior of the fish you choose, to create comfortable conditions for their existence, they will delight you for many years with their beauty and health, and many of them will delight you with numerous offspring!
We also recommend you to look at the colorful brochure “Popular types of aquarium fish”. This brochure contains all popular types of fish, with a description of their conditions of maintenance, compatibility, feeding + photos.

The aquarium is a living and developing microcosm. And the compatibility of fish species shown in the table with each other is still not an axiom.
Consider this, please. Many aquarists tell how incompatible fish get along quite normally.
I would be grateful if you share your experience of fish compatibility in the comments.
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 other fish living in this aquatic “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 that are accustomed to bite off 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.
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
- its movement and temperature
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.
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.

What species do these pets live in peacefully? In order to avoid mistakes in the settlement, should be considered their compatibility with other fish.
As a rule, they are livable with many peaceful species, however there are exceptions to the rules.
Look at the common aquarium with scalar.
Barbusses are small fish that strive to pinch the beautiful fins of any neighbors, be it scalaries or other beauties. Sometimes they live peacefully, but Sumatra barbs, cherry barbs, tiger barbs can constantly wipe beautiful cichlid angels. They demonstrate their superiority, and play catch-up, or hide-and-seek, which leads to stress.
No shelter or relocation is indispensable. Barbus even though pretty creatures, but too annoying.
In addition to them, even gourami, guppies or labo can become strongly unbelted.
Cichlids from Africa and South America – although they are close relatives of the angelfish, they can show territorial aggression and predatory behavior. Cichlids are single fish, or “family men,” not many breeders manage to keep them in peace and harmony with other aquatic creatures.
The scalar is uncomfortable with them, so the settlement is possible only with individual compatibility, which is checked at a young age.
The cockerels are good neighbors for small cichlids. Can live by themselves. Male males often conflict with each other than with other fish.
One caveat – during spawning, the female and male scalar are aggressive to cockerels, if there is no place to move everyone, arrange additional shelters in the tank.
Somiki corridor – almost all of them live without conflicts and claims, the scalar is also no exception. Somiki live in the lower layers of water, scalars – in the middle.
Each other can be ignored without interfering with living and eating.
Danio – if the fish grew together, very well. If danios are settled as new neighbors, they will be taken for food.
It will not be possible to eat everyone, they will arrange unpleasant endurance tests, proving their superiority. Danio swims in the upper layers of the water, and the scalar well they get. You can install a lot of undergrowth, shelters, a spacious tank so that everyone hides.
For small fish, constant stress is extremely harmful, so take a look at how cichlids react.
Goldfish – so luxurious fish can be maintained with a commensurate Karpov. And with the scalar content is unlikely to be successful. Goldfish live in cool water, and cichlids live in warm water.
In addition, goldfish and scalar are incompatible in nature – a more active cichlid will tear off the fins of such a neighbor. And another important factor is that goldfish quickly pollute the water, while cichlids love cleanliness.
Guppies are small ornamental fish. Get used to scalars from a young age. But when matured, cichlids can harm guppies.
In adults, the predator instincts wake up, which is extremely unpleasant for guppies – it is small, bright and beautiful. If the question arises – where are the guppies gone?
The answer is obvious – they were eaten by scalar.
Can I keep in an aquarium with gourami? Quite, gourami are non-conflict fishes that can stand up for themselves.
Rarely, territorial disputes arise between gouras and these cichlids, but they can be avoided if there is space for swimming and shelter for all fish.
Look at the confrontation of gourami and scalar.
Mollies are viviparous fishes of colorful color. Content with cichlids of this species will be successful if they grow together. Sometimes mollies gnaw the scalar fins.
Over time, they get used to each other, but in case of prolonged conflicts it is better to keep them separate.
Thorns are small omnivorous fish. Naturally, the scalars will be perceived ambiguously, or rather, as food.
According to the conditions of detention each other fit, they eat almost the same food. But terration may be physically affected by the harassment of cichlids.
Compatibility can be called relative, because for sure there have been cases where ternation and scalar have gotten along. However, terntions are small hydrobionts, large neighbors are dangerous to them.
Discus – these aquarium fish can be good companions for cichlids. The scalar and discus have similar conditions and diet.
Even their body shape is a bit identical – and discus and it is difficult for scalars to collect food from the bottom due to disc-shaped symmetry. Therefore, they and others will be able to eat with a special feeder. The differences between them are discus fish flocks, they feel comfortable in a flock of 5-6 individuals, and the scalars swim in a pair, they love a wide space.
Having a large tank for both types will be a big plus.
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.
