Goldfish compatible with other fish

maintenance, care, compatibility

Very often, beautiful decorative goldfish are the very first pet beginner aquarists. But before you start them at home, you should definitely consider the compatibility of these beauties with other typical inhabitants of aquariums.

As with all other representatives of aquatic fauna, the behavior and compatibility of all ornamental crucians are closely related. As for the goldfish in particular, the debate about its compatibility has been going on for a long time, but theorists and practitioners of aquarists cannot make a definite conclusion.

Decorative goldfish are large enough (20–25 cm in length) for domestic pets, which means that a large aquarium with a capacity of 50 liters per individual is required for their successful life. For a couple – 80-100 liters.

It would seem that such a space contributes to the combination of several species, but for this there are several serious obstacles.

  • First of all, “zolotushki” somewhat slow. Smaller, nimble fish will no doubt take their food away from them.
  • And, on the contrary, in the vicinity of the same large sluggish species, decorative crucians will pounce on food, trying to eat every last crumb. Neighbors are unlikely to get something.

Another feature of the behavior is the habit of rummaging in the ground in search of food. This happens very often, entailing the rise of silt and turbidity of water.

Not every “neighbor” will like it.

Omnivorous goldfish. At home, they eat live, dry or frozen food, as well as vegetable food.

If the neighbors in the aquarium are small fish, then gradually they will be eaten by the “little crowns” who are constantly in search of food.

Decorative carp has a bright appearance: large dorsal and ventral fins, luxurious tail. Experienced aquarists confirm: veil-shaped fins are very often the targets of aggressive “neighbors” attacks, even if they are smaller in size.

Thus, the desire to run other ornamental fish to gold often encounters a number of unsolvable problems.

Practice shows that such a neighborhood is impossible. And this is due to the natural aggressiveness of almost all tsikhlovyh.

Even if cichlids are herbivores of the same size as goldfish, then races around the aquarium are inevitable.

In some sources you can find information about the peaceful living in the general aquarium of goldfish and South American tsihlazom, however, clashes between them are inevitable. Especially if the fish are hungry.

As for the fairly common astronotus, he considers the “gold” only as an additional dish for his dinner.

Unpretentious, peace-loving tetras and neons could get along peacefully with goldfish. In principle, this is what happens when golden fry are launched into the aquarium to these popular representatives of the family of the Haracin.

As a rule, peaceful coexistence ends when goldfish grow to their normal size and begin to consider small neons, rhodostomus or minors as an additive to the usual diet.

If the neighborhood is so necessary, then it is better to keep in the general aquarium larger tetras – congos or brilliant ones, which may well get along with bright decorative crucians.

Experts say that in this case we can expect quite decent compatibility. Small aquarium catfish (tarakatums or corridors) do not consider gold as rivals, they are too calm and slow for this.

An exception can only be ancistrus or catfish-sucker, which hunts at night. Having stuck to a goldfish, this catfish can fairly beat it.

Some experts argue that the proximity to catfish will even be useful for the aquarium biotope, as the “bulls” leave behind a lot of garbage that can quickly decompose, and the catfish are by their nature bottom-level cleaners.

From the point of view of behavior and calmness in a water hostel, in this case there will be no problems. Comets, voilehwosts, shubunkins, wakins, telescopes and richens will live peacefully in a common company.

But here another problem arises: the state of the offspring. Individuals of different subspecies will begin to interbreed with each other and give hybrids.

Thus, the breed will be spoiled, and the centuries-old efforts of Eastern breeders will go down the drain. If this process is not stopped, then a rather rapid transformation of goldfish back into ordinary carp will occur.

So, with whom it is better to combine elegant goldfish? There is only one answer, with which all experts agree: with no one.

In a species aquarium, goldfish of the same breed will be calm, comfortable and safe.

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.

Watch the video about the compatibility of aquarium fish.

In nature, there are 177 species, many of which have taken root in artificial reservoirs. Small size, go hunting at night, during the day they burrow into the ground or hide.

Compatible only with plexostomus, with other fish compatibility is different, depending on the volume of the tank and the nature of each fish.

The most ancient and popular representatives of home aquariums. They have a peculiar character, besides, their color is very noticeable, therefore, they are compatible only with the representatives of their family, the Karpovs, the karpami koi.

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.

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.

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

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

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.

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 resist the barbs, 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:

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.

The restless appetite of the “tiger” will create problems for a peaceful fish, taking away its 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.

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.

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.

GOLD FISH CARE CONTENTS BREEDING COMPATIBILITY DESCRIPTION.

The best option for keeping telescopes is at a distance from all other fish and in a spacious aquarium in which water is very rich in oxygen. It will also be good to contain telescopes along with the tail fish – goldfish.

In an aquarium in which you will contain telescopes, there should be excellent air blowing and excellent water filtration. Also, it would be useful to triple the aeration of water.

Telescopes are not very good friends with plants that are not well rooted, because telescopes simply pull them out. Plants with delicate leaves, they are biting.

Breeding and spawning

The reproduction of telescopes is possible in an artificial reservoir in the springtime, when the water is warming. As in the reproduction of goldfish, the female and the male telescope are planted for two weeks in separate aquariums, giving live and artificial food.

Before settling in spawning, they are satisfied with the fasting day. Spawning occurs in fresh and softer water with a temperature of 23-25 ​​degrees. The required spawning volume is 50 liters, a separator grid and several hard-leaved plants are placed there.

Usually one female and 2-3 males spawn. The female lays many eggs – more than 2000.

Incubation lasts 3-4 days. 5 days after spawning, the larvae will hatch, which will swim in a few days if the water temperature is from 21 to 26 degrees Celsius.

The fry are weak and helpless, barely noticeable.

Starter feed – live dust. Later you can eat artemia and rotifers.

Caring for fry requires constant observation in the spawning aquarium – in order to prevent cannibalism between brothers, large fry should be separated and settled separately from smaller ones.

Compatibility of telescopes with other fish Now about compatibility with other aquarium fish. All golds are rather slow and contain them better with fish.

the same temperament, and ideally with their own kind. They are definitely not suitable for neighbors, so to speak, fast-moving fish (such as shark balls), which can easily cause gold injuries.

There is also no talk about suckling fish, such as gerinokhailus or antsistrusov with pterigoplichtami, as they like to travel around the aquarium, clinging to slow-moving fish.

These travels do not pass without a trace for the “cab driver”, traces remain on the body of the fish, and they are far from harmless. On the ground, the scales often peel off the scales, or even bloody wounds remain.

Telescopes, like all goldfish, become sexually mature in the second year of life and can reproduce from now on. In the aquarium under optimal conditions of existence of the fish, telescopes live up to 15-17 years.
