maintenance, care, compatibility
Compatibility of aquarium fish – a very important issue for beginners and experienced razvodchiki. Each fish has an individual character, style of behavior, regardless of whether it is a herbivore or a predator. Some fish quickly eat plants and shrimp, others attack the fish themselves.
Of course, there were cases when practically incompatible species coexisted in one reservoir.

To systematize this issue, you should familiarize yourself with the habitat conditions of each hydrobiont, and then decide who to share it with. Assess the degree of aggressiveness of each species, the water parameters that are acceptable for them, in which layers of the reservoir they usually swim.
To ensure that your aquarium is filled with life, a table is provided that lists the compatibility of freshwater fish.

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.
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
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 particular area, where they inhabit the fish of various families living in this area.
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:
- 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.
- 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.
- 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. 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.
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.
Aquarium fish compatibility chart
|African cichlids||Limited compatible||Absolutely incompatible||Absolutely incompatible|
|Barbusses||Limited compatible||Fully compatible||Absolutely incompatible||Fully compatible|
|Goldfish||Absolutely incompatible||Fully compatible||Absolutely incompatible||Absolutely incompatible|
|Danio||Absolutely incompatible||Fully compatible||Absolutely incompatible||Fully compatible|
|Gourami||Absolutely incompatible||Fully compatible||Fully compatible||Limited compatible|
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 “crack down” with all the inhabitants of the aquarium; Quiet guppies will not live long in the same territory with aggressive and warlike cichlids. Goldfish cannot exist with danios, gurus and scalar, etc.
1. 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.
Neons are small freshwater fish of the Kharatsin family. In the wild, they are very active and brisk, able to quickly hide from predators, maneuvering among thick plants.
Body size reaches 3 cm in length, life expectancy depends on water temperature: from 1.5 years to 3 years. Behavioral characteristics: due to a peaceful disposition, they can live together with each other in a flock, as well as with other species of fish.
Guppies and neons, petsyli and neons, catfish and neons get along well in the same aquarium. Such compatibility is beneficial for novice aquarists, since these types of fish will definitely not harm each other.
What else should be considered in compatibility? Males of neons are brighter in color than females, the contrast of scales depends on the species.
But one thing unites them – a horizontal strip passes through the body, which glitters with “neon” shimmering even in darkness. This feature can be attractive to predatory fish and those who do not welcome next to their more beautiful neighbors.
So settle a flock of neons of 5-7 fish and more in a spacious tank with shelters so that in case of unforeseen attacks, they can hide in time.
Neons are characterized by calm behavior, and only during the spawning season they become overly active and cocky. Therefore, choose as your neighbors for them fish are not predatory, but omnivorous or herbivorous, balanced and not very playful.
There are a number of rules that are important to ensure that the compatibility of neons with other fish in the aquarium is the most successful.
Look at the successful version of the general aquarium with neons.
- Compatibility is possible between fish that live in the wild in a similar environment. Neon fish live in water at a temperature of 18-24 ° C, pH 5.5-7.5 pH, hardness 8-20o. Therefore, their neighbors in the aquarium should be adapted to the same parameters.
- Neon cannot be settled with large predators that feed exclusively on meat and carrion. Otherwise, peace-loving neons will become prey for them – the fins can be cut off, at a minimum.
- You can not settle in the general aquarium fish large and small, such an incompatibility can cause severe stress, or loss of bright body color.
- Choose neighbors, similar in temperament. Small and nimble fish will feel comfortable in the company of calm and not fast fish. What is it for? The fact is that the activity of fish can cause fluctuations in water, which can lead to stress.
- Neons are schooling fishes, not loners. They feel well in the company of the same kindred, the fish alone will not live long.
Neon get on well in the home pond with such aquarium fish: Pecillia (guppies, swordtails, mollies, placiums), speckled catfish, panda, tetra, danio rheo, labo, rastar, minors, gourami, iris, pulcheras, minors, hyacinths, sweaters, laboratories, rasomes, minors, gourami, iris, pulcheras, minors, marines, sweaters, minors, gourami, iris, pulcheras, minors, and fish. Consider compatibility with some fish in more detail.
See how well the scalar and neons get along in one aquarium.
Somiki corridor are excellent neighbors for small haracin ones, live together in the bottom layers of the aquarium, and collect remnants of uneaten food. The corridors are innocuous fish, also small and peaceful, they love to watch their neighbors without harming them.
Rasbory – can make an excellent company neon. Among them: the actual rasbory, boraras, microassemblies and trigonustigma, some of them belong to the family Karpovye.
Fishes of the Family Petsilievye (guppies, molly, sword-bearers, petsilia) – peacefully cohabit with haracin. Swordtails also have small body size, but males may be excessively active.
It should be borne in mind that more than two swordtail males sometimes pursue smaller neighbors, especially during the spawning period. With insufficient feeding, in the cramped, small place for swimming, the swordtails become unbearable.
So that these fish do not terrorize small neons, the aquarium should be spacious, with a sufficient number of plants and shelters.
Neons are poorly compatible with such fish:
- Large catfish, cichlids, barbs, astronotus, cockerels, koi carps – those who live in cool water, or have a predatory, aggressive behavior.
- Goldfish – they live in cool water, and are aggressive towards bright fish and their offspring.
- Angelfish – can live with neons only under the condition that they all grew up with the age of young animals. But neon-stranger scalar will be perceived as food. Also during the mating season, the scalar will be aggressively inclined towards everyone, including these small fish.
The compatibility of goldfish with other types of fish is one of the necessary conditions for their harmonious life in a home aquarium. From the correct compatibility depends on the health of the fish, behavior, life expectancy. Before determining with which species of fish the content of goldfish is possible, many observations were made that began in the Middle Ages.
Since the goldfish (lat. Carassius auratus) is one of the oldest aquarium pets, compatibility has long been tested, which allows settling it with other fishes without experience.
- Decorative varieties of goldfish are very large creatures with a body size of 20 cm in length and more, therefore, a successful maintenance requires a reservoir with a volume of 50-80 liters per individual.
- This type of fish is slow and graceful, so more active neighbors will disturb them.
- “Cinderella” love to plow the ground, looking for food in it or digging up plants. Such a habit is common to all, so the water will become dirty and muddy in a short time. Fish that love crystal clear water will suffer.
- They are omnivorous – they eat live, frozen, vegetable food. Diet with neighbors in the aquarium should be the same.
- Goldfish can eat very small fish. As representatives of the carp family, they borrowed from their ancestors a tendency to eat small animals.
- Compatibility is also affected by their variegated, beautiful color, as well as lush and long fins. Content is not allowed with those species who are not averse to nibbling their sumptuous tail.
See how goldfish coexist with macrognatus, labo and thoracatum.
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.
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.

Settling an aquarium is a demanding, painstaking task. It requires theoretical knowledge.
Fish may have full or relative compatibility and be completely incompatible.
Most likely, representatives of the same family, detachment, suborder, having the same size and conditions of detention can get along. Common sense will not allow the inhabitants of cooler waters to settle in tropical conditions.
Predatory large species can cause serious harm to miniature water inhabitants. But there are exceptions in any rule, which is confirmed by experienced aquarists.
There are many cases where peace-loving fish friendly cohabited with fierce predators for a long time. At the same time, baseless wars often arose between calm fish.
If you are still not sure that water inhabitants are compatible, you can always use special tables. They contain information that will dispel your doubts and prevent you from making irreparable mistakes.
Look at the aquarium with guppies, lyalius, neon and catfish.
