What kind of fish to have a novice aquarist?

In order for the fish to please their owners and to reveal the amazing underwater world to the aquarist, they need to provide comfortable conditions of detention. At the same time, they should feel safe and not be constrained in their movements.

Preliminary preparation before the acquisition of small fish

If you have never had an aquarium and no experience of keeping fish, then it is best to start fish that need minimal care and are not very demanding to the conditions of existence. This will avoid the death of your fish, as well as gain experience and knowledge in the content of the aquarium.

Many tropical fish require the maintenance of a certain water quality (hardness, acidity, temperature, etc.), the presence or absence of plants, a certain brightness of the light or its absence.

For unpretentious fish, the range of comfortable conditions is much wider, which allows them to be kept in a lower-quality environment. They are also less susceptible to negative factors (improper feeding, delayed water changes, etc.).

There are several determining factors when choosing a fish:

  • aquarium size;
  • selection and compatibility of different types of fish;
  • the size and temperament of the fish.

If you already have an aquarium, you need to determine what and how many fish you can fit into it. This will avoid overpopulation, which leads to unnecessary fights, oxygen starvation, eating predators of peace-loving fish.

Aquarium size

If you have enough space and money to install an aquarium of any acceptable size, as well as the necessary equipment to ensure the life of the fish, you can proceed to the next heading of this article.

If you are cramped in something, then you need to define your desires, given that small aquariums are much more difficult to maintain than large ones, but the latter require more time for maintenance. For example, a 100-liter aquarium will suit a novice aquarist better than a 50-liter aquarium.

A large aquarium is simpler and better kept for several reasons:

1. Water temperature and quality are more stable.

2. The impact of adverse factors on the fish takes longer, which gives the novice aquarist the opportunity to influence them in a timely manner. For example, in winter time, the water heater broke, the cooling process is slower and you can manage to get off and buy a new one before the fish get cold. Or ampularia died from old age in the thickets of a small aquarium, the water became dull, the smell appeared, fish began to die. In a large aquarium, this process will occur many times slower and you can remove the dead snail from the can without harming the fish.

3. In small aquariums there is little space for free swimming, and, accordingly, not every favorite decor can be placed in it.

4. Ample opportunities for design and decoration.

5. A large aquarium can hold a lot of large fish or a large number of small ones, it allows you to contain various types of fish.

With all the advantages of large aquariums, it is sometimes not possible to install it. Small aquariums are great for apartments, country houses or hostels, as well as for the second floors of private houses. Large aquariums weigh a lot, they are difficult to transport, take up more space, and in unforeseen circumstances cause more damage.

The biggest advantage of a small aquarium is a financial issue. Aquarium, equipment, scenery, soil, plants, the cost of electricity, the treatment of fish cost much less.

Before acquiring you need to properly assess the benefits of both large and small aquariums. Answer yourself the question: "How much aquarium would you like and is there a possibility to contain such a volume?" If finances are not important, and you do not often move, then the choice is obvious. And if you do not want or can not afford a large aquarium, then a small aquarium is what you need for you. In any case, the main thing - comfortable conditions for the maintenance of fish.


Selection and compatibility of different types of fish

In order to determine which fish you like, just read the literature, watch videos, go to a pet shop or to the bird market. Make a list of the types you like most.

This list should be a little more than you will purchase. Subsequently, it turns out that not all fish are suitable for your aquarium, some are incompatible with each other, parameters or temperature conditions will not work for others. But the abundance of species in the fish market will allow you to finally form a list of the inhabitants of your aquarium.

To understand how roomy a settled aquarium is, you need to carry out simple calculations. In various information sources they vary. Some are based on the oxygen demand of adult fish, given the surface area of ​​the water. Some cold-loving freshwater fish require 192 cm2 and tropical ones 64 cm2.

Other calculations averaged justify - one liter of water is needed per cm of body length of an adult individual (for example, you can run five fish of 4 cm each in a 20 l aquarium)

For a marine aquarium, for each fish 2.5 cm long at least six months old, 18 liters of water are needed, and for later age 9 liters.

Some fish species share the size of the aquarium geographically and protect their habitat from other representatives. This leads to a decrease in the number of inhabitants in it.

At the simultaneous maintenance of different species need to pay attention to even the acquisition of fish. The key to a good selection of pets for an aquarium is the following conditions:

  • similarity of climatic conditions (it is impossible to combine freshwater and saltwater fish, freshwater and brackish water bodies);
  • about the same hardness and acidity of water;
  • the same temperature;
  • similar conditions on the speed of flow, soil quality, the presence of thickets and shelters, lighting.
Fish are doing well in conditions as close as possible to their natural habitat.

When settling an aquarium, it is necessary to take into account the preferences of species with respect to their location in the layers of the water column, and try to evenly distribute them.

The size and temperament of the fish matter

Important parameters for species compatibility are their size and temperament. Of course, it is impossible to contain predators and herbivores in one aquarium, otherwise the latter will become food. In the wild, larger fish eat smaller ones.

Even if you only have herbivorous fish, you need to check that the size of the smallest fish is larger than the largest mouth opening of the fish in the aquarium. This will avoid unnecessary casualties.

Certain fish are territorial and do not let other species close to their habitat. There can be many reasons:

  • suitable food supply,
  • the spawning ground arrangement (the couple who carry out the treasure jealously guard the nest),
  • the presence of water turbulence with optimal temperature parameters, etc.

Differences in species manifested in modes and methods of feeding. For example, somobraznye eat food from the bottom, petsliiliformnye - from the surface. Some kind of fast and agile, and some - slow and unhurried. Fish require different food, and if you do not like it, it is better to choose pets with the same way of feeding. If you do not follow the feeding regime, then some species will be hungry and others will be overfed, which will lead to a reduction in the life span of all inhabitants.

Often, fish are acquired that have not reached puberty, which leads to incorrect judgments about their temperament. Therefore, in order to fully determine whether this fish suits you, it must grow and be in comfortable conditions. Of course, if any representative is unnaturally pugnacious, cuts off fins or clogs other fish, it should be isolated.

Fish, the most suitable for beginners

This topic is hot and is discussed in many forums. There are many types of fish that require minimal maintenance. This allows you to choose the most suitable pets for each novice aquarist both in a variety of colors and in size. The aquarium can be equipped with beautiful relief and plants, and originality will give a contrast to the color of the fish.

Very often, beginners choose viviparous fish such as swordtails, plazii, guppies, mollies, etc. And this is an excellent choice. They have a good survival rate, are easy to maintain, are active, have a long lifespan and do not require strict conditions of detention.

There are some types that are ideal for beginners.

Guppy - fishes of the Petsiliev family, with a peace-loving character, calm and unhurried in behavior. Coloring is very diverse and beautiful. To the composition of the water does not impose requirements. Periodically you need to change the water. Viviparous Easily distinguished by sex. Males are much smaller, more beautiful and brighter. Omnivores. Overfeeding is not recommended. Easily tolerate a decrease in water temperature to 15 ° C.

Swordtails - Family Peziliye. Have more than 25 decorative varieties. In the male, the tail fin has the shape of a sword. Very beautiful fish that does not require special conditions and specific size of the aquarium. Viviparous, easily reproduce. When the fry appear, the parents should be moved to a free container to avoid eating the children.

Gourami - mobile fish, differing in an interesting spotty color, are curious. To other species of fish and inhabitants are tolerant. They can breathe not only air dissolved in water, but also oxygen directly on the surface. Black out.

Somics different external originality. Unpretentious, peaceful, eat any food from the bottom. Clean up the remnants of food uneaten by other inhabitants. Orderlies aquarium. Prefer bottom-living and easy to get along with other species.

Neon - Representatives of the Kharatsin, there are more than 150 species of fish. The most common among beginners are red and blue. The content is simple, undemanding to water. They love the space, the length of the aquarium should be at least 50 cm. Excellent jumpers, so you need to cover the surface of the water with glass or a lid.

Danio - schooling, bright, beautiful fish. Aquarium is needed with a length of at least 55 cm. Very mobile and like space. Requires regular water changes and good aeration. Great jumpers, so you need an aquarium with a lid or glass. Prefer good lighting and clear, clean water.

Barbusses - schooling fish. There is a huge variety of species (more than 200). In the schooling content of peace. Very active. It is not recommended to keep them with fish, the tail of which has thread-like or voile forms. They love floating plants.

gold fish - representative of the carp family. It is very popular, but it requires a large volume of aquarium (per adult of at least 35 liters of water). Prefers clear, clean water and requires its regular substitution. Very voracious, so you need to be careful with feeding. Prone to overeating.

Antsitrus - somobrazny, herbivore. Very good orderly, nibbles small shoots from the glasses of the aquarium. The oral opening resembles a suction cup. Males are distinguished by a large number of whiskers. Peaceful. It is recommended to feed tabletized plant spirulina.

Presents the most common, unpretentious, do not require special care fish that are suitable for beginners. But this does not mean that they do not need to be watched, to know their preferences, the temperature of the water, etc.

Tips from personal experience

  • When buying, it is better to purchase young and healthy fish (active, without external signs of disease).
  • Before launching into the aquarium, it is better to stand for 3-5 days in a separate container.
  • Buy better for 5-10 pieces, it will avoid same-sex.
  • You need to choose 2-3 kinds of fish. 1-2 basic, third extra. For example, mollies and gourami as the main species, and ancytrus as an additional. The first two types are active, mobile, well contrasted, and ancytrusians will be orderlies.
  • It is best to buy aquarium, equipment and fish in a bird market from one seller. He will remember you, and you can take his phone number without any problems and consult on unclear questions.

What kind of fish is better to start a newbie?

New aquariums are very unstable due to the fact that they did not form the necessary microflora (beneficial bacteria that remove harmful substances). And even if you add bacterial preparations (they are sold in pet stores), conditions may not be suitable for delicate fish.

Discussions are very beautiful. And very complex.

Fish that are generally not worth starting for beginners, we reviewed here. Here is a list of fish that can be problematic:
Algae-eating catfish - antsistrusy, loricaria, otocyclones. They just will not have enough food.
Somiki digging in the ground - they need a solid feeding, which falls to the bottom, and it is alike to feed fish in a new aquarium.
Hybrids - fish obtained as a result of breeding, as a rule, have weakened immunity and are demanding of conditions. For example, discus, bright forms of guppy.
Large species of fish are usually aggressive, they should also be the first to get them.

Swordtails are a good choice.

What remains among the fish for beginners? Yes, many species. (And we also have an article: Top 10 aquarium fish for beginners) For example:

  • Guppies of simple breeds are an amazing example of unpretentiousness.
  • Mollies - coal black beauty and not demanding of conditions.
  • Gourami, such as marble. Can live almost without oxygen in the water.
  • Males are very beautiful and not demanding. Just do not plant them with their own kind! About roosters by reference
  • Sword bearers and petilia are active, vibrant and livable.
  • Danio - grace and small size.
  • Tetras are neons, ternuts are wonderful peaceful and beautiful fishes.

It is difficult to immediately understand which fish are suitable for you and will live. Advice - start with the simplest ones, guppies, for example. Let them live with you for a while. You will learn the tricks of aquarism, and go to the more complex types.

COMPATIBILITY OF GOLDEN FISHES



COMPATIBILITY OF GOLDEN FISHES
WITH OTHER FISH SPECIES

Compatibility issue Goldfish (Carassius) on the one hand, it is rather simple, but on the other it is complicated, and this is due to a number of specific nuances that are characteristic of this particular family of aquarium fish.

I think this topic should start with the fact that ALL BREEDS OF GOLDEN FISHES were obtained as a result of millennial selection. Therefore, the Voilehvost, Orandy, Telescopes, Shubunkins and others are artificially bred breeds, which, in fact, were obtained from one ancestor - silver carp.

Therefore, if we talk about the intraspecific compatibility of Goldfish, that is, the possibility of sharing, for example, telescopes and koi carps in an aquarium or a pond, then this coexistence takes place - all types of Goldfish are absolutely compatible with each other. But, HERE THERE ARE ONE BUT! Since all the Scrofula are from the same tribe, they are in the same reservoir, they will interbreed with each other, resulting in "bastards" or if you want mutants - outbred hybrids. Taking into account the experiments, such a joint residence leads to degeneration and the transformation of the fish back into a crucian.

Therefore, if you plan to get offspring and breed Goldfish, then their species content in the general body of water - PROHIBITED!

Before the discussion, the specific compatibility of Goldfish with other fish. It should be noted that Goldfish are large, slow, slow-moving fish. And this specifics should definitely be fat. For example, if you keep the Veiltails in a small aquarium with others, whether they are the most peaceful fish, all the same, over time, the fish will die, since the lack of free space - standards of maintenance, will do its job and the fish will simply “gnaw”.

In addition, when discussing the compatibility of any species of fish, it should be borne in mind that a single fish taken has its own character. In this connection, even observing all aquarium compatibility rules, you can get a negative result. In order to maximize this factor, it is always recommended to plant different fish with young and at the same time, rather than gradually add new ones to old ones.

Now let's look at the compatibility of Goldfish with specific species of other fish.

Goldfish and Cichlids: Astronotus, Angelfish, Discus, Akara, Apistograms, Parrots, Tsikhlazymy: diamond, black-striped, Severum and other cichlids.

Such a union, alas, is not possible. All the fish of the cichlid family are aggressive and will not give life to the golden fish. Astronotus generally perceives Gold as a good live snack.

Therefore, to keep them together is strictly contraindicated, even with small cilida.

Somehow, I tried to combine veil eyelids with Goldfish, but alas, they had to be planted in the future. Despite the fact that the veil scalars are slow and somewhat similar to gold, all the same, after a couple of days, races began throughout the aquarium.

So, I recommend not experimenting - this is wasted time and money!

Goldfish and Tetras: neons, minors, ternistus, pulcher, lanterns, glass tetras, congo and other characteristic fish.

Here the situation is fundamentally opposite.All tetras are so peaceful fish that their union with Goldfish will be a wonderful variety of fish in your aquarium. One, but !!! When Goldfish grow up, they may burst into small tetras, therefore it is better to take “large” Kharacin fishes, for example, ternets or Congo, to Zolotuha.

Goldfish and Labyrinth: all gourami, lyalius, macrapods dr.

I do not even know what to say to you. On the one hand, they are compatible, but on the other hand they are not. This is due to the fact that the labyrinth, in particular gourami, very unpredictable fish and each individual gourami has its own character.

So that it is clear, I will give an example from my experience. Once upon a time, when I started my first aquarium of 35 liters and stuffed a bunch of fish there, including two marble gouramies, the latter were like mice, did not touch anyone and coexisted peacefully in the “little hostel”. But when one day I planted another blue gourae into a large aquarium, he made such a riot that it was bad even for small cichlid. I had to take her back to the pet store.

At the same time, lyalius - these are scared fish, I have no experience, but I think that it will be bad for them with Goldfish.

In view of the above, the coexistence of Gold with Labyrinths is a confusion, so this neighborhood is not recommended.

Goldfish and Aquarium Catfish, other bottom fish: corridors (speckled catfish), antsistrusy (catfish sucker), fighting, akantoftalmusy, green catfish brochis, tarakatumy and others.

In general, there is 100% compatibility. I draw your attention, only that not all somas are very peaceful. For example, Botsia Modest or Bai are somiers who can bite. Or, for example, ancistrus at night can easily stick to sleeping Goldfish, from which the latter will look like plucked hens.

Otherwise, everything is OK! Moreover, all aquarium catfish are good helpers in the fight with poop from Goldfish. Provide an aquarium bottom to the catfish and the frequency of the aquarium floor siphon will decrease.

Goldfish and carp: barbusses, danios and others.

It should always be remembered that Goldfish are slow and any neighborhood with nimble fish, and even more so those who can pluck them is not desirable. I do not see anything criminal in the joint content of danios and goldfish, but I do not recommend barbs. Sumatrans easily bite Golden.

Goldfish and pezillium, viviparous fishes: guppies, swordtails, mollies and others.

I read somewhere that guppies can attack and bite off Goldfish! But, something I can not believe in these stories. I can’t even imagine how this gopeshka will be able to covet on a big Golden Fish, unless they attack the crowd))).

I admit honestly, I don’t have any experience in keeping live beetles and Goldfish. And in general, it is somehow not solid to keep golden aksakals of the aquarium world and unpretentious live-bearers together.

And I also want to offer you such a topic as Compatibility of Goldfish and aquarium plants.

Who started up Goldfish knows that this issue is acute, as the Golden family well just loves plant food. To avoid the disgustingly plucked aquarium plants, I give my Golden twice-weekly grown duckweed from another aquarium. It is also possible to recommend to keep Goldfish with aquarium plants that will be too tough for Goldfish: Anubiases, microsoriums, cryptocorynes, as well as mosses.

For more on this, see this article - FISHING EATING PLANTS WHAT TO DO?

Summing up, it should be said that, nevertheless, Goldfish are fish intended for a specific aquarium that require special, special attention. Moreover, the cost of these fish is quite high, they are long-lived compared to other inhabitants of the aquarium and therefore it would be a shame to lose such a fish due to the fact that some five-kopek antsistrus did not let her sleep at night.

Compatibility of aquarium fish with other fish

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.

Often this rule also works with relative compatibility of fish and even sometimes with non-compatibility. For example, zebrafish can get on with small and medium-sized cichlids, just because they are nimble and swim in the upper layers of the aquarium without interfering with the cichlids.

- 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 another 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;

- the size of the fish;

- The parameters of the aquarium water and the 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 scalars, are South American cichlids, who quietly get along with each other. 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 one can sometimes achieve 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 somas are not just predators, but "fierce killers." In their homeland, in Asia, they exterminate all the fish that are in their reservoir, and when no one is left, they crawl out onto dry land and crawl to the nearest new reservoir behind the “new victim”, while 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 innocuous 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 - this is the overgrowth of the aquarium !!! Every aquarium pet should live in a comfortable environment, and not in a "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 "beat 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 tables.

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 my attention 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 living plants, then I do not recommend buying goldfish, African cichlids, labo, metinnis, tetragonopterus, 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.

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.

Shiny neons

Danio - rerio

Striped aquarium danio inhabitants - rerio, another ideal option for a 20 liter reservoir. In addition to its cheerful multi-colored danio cheerful, lively and very active. That is why will become a real decoration of a small aquarium at 20 liters.

They are not picky, as they can live in water in the temperature from 16 to 30 degrees, they love vegetation and are satisfied with good natural light. Feed preferably live food, such as daphnia, cyclops or live moth. It is easy to spawn and feel best in flocks.

Friendly Guppy

The most common inhabitant of home aquariums, guppies, will not bring any trouble to their owners, which is why they are considered the best option for beginner aquarists. In addition, guppies, in addition to unpretentiousness, have many beautiful colors and are distinguished by their fecundity. After several weeks of dwelling in a 20 liter aquarium, you can find a huge number of fry, which is quite difficult to catch.

Guppis eat absolutely everything and can perfectly survive a week-long hunger strike, tolerate absolutely any temperature and can be content with natural light. But in order for the color of the fish to acquire a richer palette, it is worthwhile to install artificial lighting, pay attention to frequent feedings and periodically change the water, pouring approximately 1.5 liters of water into the 20-liter aquarium once a week.

Cardinals

A beautiful slender cardinal is considered one of the few fish that feel great in a small aquarium at 20 liters. The cardinals have a beautiful brown-olive color with a silvery sheen. The tail fin is bright red and has small yellow stripes. Cardinal fish in small spaces of the aquarium can reach approximately 4-5 cm.

Cardinals of friendly fish, which is why it is better to keep them in small flocks in the company of red neonchikami, danios or rhodostomusami. To make the cardinals feel at home, you need to decorate a 20-liter pond of small size with vegetation. And as the feed is perfect dry mixes and live food.

Norman Blue Eyes

A cute blue-eyed schooling fish is an ideal solution for a small aquarium. Experts believe that even in a vessel of 10 liters, these fish will be able to swim enough. A distinctive feature of the blue-eyed bird lies in the bright framing of the eye shell, which glows with neon light, thus making the atmosphere of the aquarium unusually charming.

Peaceful but a little shy blue-eyed bird will live in peaceful species of fish, but it’s better to keep large inhabitants away. Sineglazka loves various shelters, vegetation, dark ground and some free space. Eats almost all types of live food and does not disdain substitutes.

Luxurious cockerels

For beautiful cockerel fish, owners of luxurious fins and bright colors, also a reservoir of a small number of liters is also ideal. However, for the maintenance of these fish it is necessary to create certain conditions. For example, too low or high temperature can lead to diseases that will lead to the death of males. A prerequisite is the replacement of water, about a few liters per week,

The daily diet of fish is live food. You can use frozen food, or dilute their diet with flatworms or snails. They get along with swordtails, minors, catfish, gourami, etc. But active guppy fish, neons, barbs can inadvertently damage the rooster's fin fin, which will lead to fighting battles.

Aquarium fish and their homeland

This seemingly purely cognitive question has practical application. The climate and living conditions in different regions of the continent is very different, and therefore often some inhabitants of water bodies simply cannot exist together. Experienced aquarists are trying to settle in one tank wards, which fit almost the same temperature and rigidity of the aquatic environment.

The origin of popular aquarium fish
