FISH KNIFE—Name of aquarium fish

The role of the aquarium in the apartment is interesting: a piece of the water element, placed in the interior of the citizen’s dwelling, is an excellent element of decor, as well as a means for relaxation after a busy day full of stress. Aquarium fish, embodied in your apartment in miniature, will bring you a lot of joy.

But when starting an aquarium, it is important to understand what types of aquarium fish will live in it and how.

Leafing through the catalog, delving into the photo and names of aquarium fish, first of all, you should decide on the purpose of the upcoming purchase: do you want to engage in breeding or start an aquarium of aesthetic motives?

Breeding takes a lot of time and effort, as certain species of aquarium fish require special conditions for reproduction. You also need to find out under what conditions a particular species of aquarium fish will acquire the desired external parameters (the appearance and temperature of water, lighting, and the nature of food can significantly influence the appearance).

Creating an “underwater world” with an aesthetic goal is a somewhat different task from selection. Here you are primarily in the help of catalogs, in which various types of aquarium fish in pictures are presented.

However, here, studying photos and descriptions of aquarium fish, you should choose the inhabitants of the aquarium, which require similar conditions of detention and are not part of each other’s food chain. Failure to follow these principles will lead to disease and death of fish.

Many years of work of aquarists and breeders have led to the fact that all the names of aquarium fish can not be mentioned even in the volume brochure. Therefore, below we provide a table that includes a brief description of the most common individuals.

In order to have less discord in your tank, its inhabitants should not be cramped. For each fish up to 5 cm in size it is necessary to have 8-10 liters of aquarium volume, 10 cm in size – 15-20 liters, over 15 cm – 25-30 liters.

These figures are not “the truth of last resort” and are given with a certain margin, but they should not be exceeded. Do not forget that plants and soil in your tank also take up some space.

Remember that some species of aquarium fish can produce offspring only if there are no “alien” neighbors around at all. In other words, there is often a situation where a certain type of aquarium fish, capable of living in a common aquarium, breeds only in a “species” domestic pond.

No matter how much you like the photos and the names of the aquarium fish from the catalog, new pets cannot be moved into the general aquarium if they are incompatible with those that already live in your home pond.

You can create a set of fish for the aquarium yourself using the table below.

Also a good solution would be to use one of the time-tested sets of aquarium fish.

There are aquarian inhabitants who feel great and look great in pairs or even in one copy. And there are those who are better to keep in groups.

Packs can be simple, in which all the fish are equal and the leader, depending on the situation, can be any, or hierarchical with a permanent leader and participants who clearly know their place. The pack has its own advantages: the fish are better protected from enemies, it is more convenient for them to eat, they are less nervous and, finally, they look very advantageous.

Let’s briefly consider the main types of schooling aquarium fish, for convenience, arranged in alphabetical order.

Aquarium fish – DESCRIPTION

For many, aquarium fish are very often the favorite pets. Their names are very diverse and amazing.

Many of them speak for themselves, but the beginning amateur has not even heard about most types of aquarium fish. It is amazing to watch these bright multi-colored creatures. Psychologists say that after a short period of time observing aquarium fish, a person regains mental balance, stress passes, blood pressure returns to normal.

The carp fish family, among which such species of aquarium fish as the goldfish, barbus, danios, can rightly be considered the most common in modern aquarism. The next most popular family of fish – Persian. The sword-bearer, guppy, petilia

and mollies – these types of fish became the first experience for many aquarium lovers. Also, somiki success.

A lot of interest are the types of fighting and antsistrusy. The popularity of such a family of fish as the Cichlids-Predators is constantly growing. Many species of fish of this family, such as discus, astronotus, tsikhlazomy and chromis, are now very widespread.

Do not forget about other families of fish, for example, Labyrinths with their beautiful representatives – liliusi and macropods. Fish are representatives of the class of vertebrate animals, their habitat are fresh and saline waters. This ancient group, according to some scientists, exists on the planet for more than 430 million years.

There are practically no reservoirs on Earth in which certain species of fish would not live.

It affects not only their great diversity, but also the ability to adapt to different conditions. Exotic fish that are kept in aquariums often have a very interesting body shape, small size and beautiful color. As a rule, they are thermophilic and feel comfortable at a temperature of at least 19-21 degrees, but some species withstand even lower temperature.

Look often for the general condition of the inhabitants of the aquarium world. Look, whether aquarium fish are sick, whether their behavior is normal, whether there are different types of growths, bruises, wounds on them. All unnecessary items immediately need to be removed from the aquarium, suspicious fish should be deposited in a separate aquarium, especially carefully monitor them, try to find out the reasons for their abnormality and, if possible, identify any symptoms of diseases

.Under the aquarium fish refers to fish, the content of which is possible at home and for which there is a demand among aquarists. Aquarium fish in the shops sell a huge variety and it is not surprising that many novice aquarists are confused and take the wrong aquarium fish. This leads to problems.

And so to say the advice on the track – trust only trusted aquarium shops, read more yourself and listen to less sellers. Before you buy anything, find out whether the store has specialized in aquarium fish for a long time, and whether complex types of fish are on sale.

But if the place to buy fish is doubtful, just hold that purchased fish are 2-3 weeks in a separate aquarium to observe and clarify the issue of their health.


Aquarium fish – ornamental fish, which are kept in aquariums. The first mention of the artificial breeding of fish in China is dated 1500 BC. er For most of the aquarium fish is characterized by a bright decorative color, fancy body shape and small size.

Goldfish are considered the most popular aquarium fish.

The popular aquarium fish also include: danios, anscistrus, barbs, angelfish, catfish, neons, nanostomuses, labo, discus, guppy, etc.


Maintenance and nutrition of aquarium fish.

Usually in aquariums may contain several species of fish. Here you need to very competently approach the combination of various species in the aquarium.

It is necessary to take into account the compatibility of the color of aquarium fish, the proximity of the conditions of detention, the similarity of behavior.

Pay attention to the presence of oxygen in the aquarium (with its lack of fish rise to the surface and swallow bubbles of water).

Very important is the temperature of the water (if the water is too cold the fish will be lethargic, if too high – they will be thrown vertically around the aquarium).

Lighting is also very important for fish – the light day for fish should last 10-12 hours, so do not forget to take care of purchasing a lamp that corresponds to the volume of your tank.

To eat aquarium fish should be diverse, full and correct. Usually, fish are fed 2 or 1 time per day, usually 1 hour before and after switching on the light.

It is also useful to arrange a so-called hungry day 1 time a week – then the probability of obesity in fish is reduced.

It is very important not to overfeed the fish, as food remains, not eaten and trapped in the soil, rot, which leads to turbidity of water, and therefore the disease of fish.


There is a huge variety of species and subspecies, families, genera, orders and sub-orders of aquarium fish.

This information is mainly used by experienced breeders and razvodchiki fish. We will consider the families and types of fish that are most common in home aquariums.

The carp family is considered to be the most popular aquarium fish, among them such species of fish as the barbus, goldfish, danios.

The second most famous is the family of kartozubyh fishes. This includes such species of fish as the swordtails, guppies, mollies, petilia.

Various catfish are very famous, among them antsistrusy, fighting are especially known. Next in popularity are the cichlids family, for example, such fish species as scalar, chromis, discus and tsikhlazomy.

Also, a significant part of aquarists prefer labyrinth families of fish, such as cockerels, lyalius and macropads.

These are calving and viviparous fishes. Breeding aquarium fish are those fish that spawn in the ground or on plants, and then fry appear from it.

And viviparous aquarium fish are fish that immediately produce fry, which can do without the help of parents. It should also be noted that among the aquarium fish there are predatory fish that feed on smaller fish than themselves.

Aquarium Fish Decoration Aquarium

So, how to feed, we figured out … And what to feed aquarium fish?
All feed for aquarium fish can be divided into four groups – branded, frozen, live food and vegetable food.

If you want to keep a healthy fish with a beautiful color, it is better to feed all kinds of these feeds. Of course, some fish can eat only live food, others only vegetable.

But for ordinary fish, the ideal diet consists of branded feeds, regular feeding with live feeds, and not regular plant foods.

Branded feed – provided that you buy real ones, and not fake, can be the basis of the diet for most fish. Modern branded food for fish, contain all the necessary substances, vitamins and minerals, so that the fish was healthy. To buy such food is no longer a problem, and the choice is huge.
Separately, I will note the so-called dry food – dried gammarus, cyclops and daphnia. Extremely bad feeding option for any fish.

Does not contain nutrients, poorly digested, allergen for people.
But do not use dry food – dried daphnia, there are almost no nutrients in it, fish suffer from stomach diseases and grow poorly!

Aquarium fish Diseases

The most important step in the treatment of aquarium fish diseases is to establish the correct diagnosis.

Encyclopedic knowledge of diseases is not enough here, we need considerable experience for a long time already engaged in aquarium fish people.

When studying the history of the disease of fish, it is necessary to note the following factors:

– before the onset of the disease, whether new fish or plants appeared in the aquarium (infection is possible);

– there may have been a sharp drop in temperature or composition of the water (then colds can occur);

– what changes were in the behavior of aquarium fish (fish sluggish, move a little, or rub against stones, soil, refuse to eat, etc.).

After studying the history of the disease, changes in behavior, you should examine the body of the fish (whether the color has changed, the appearance of spots or tumors, the destruction of the fins, and the clouding of the eyes).

And only after that the verdict of one or another disease is rendered. Beautiful you aquarium fish.

Do not forget about the other families of fish, such as Labyrinth with their wonderful representatives – males, llyausami and macropods.

Mollies content feeding compatibility spawning care description

Here are the most popular types of mollies: black mollies (lira-molly), Velifer mollies, sailing mollies, sailing mollies. Silver mollies (also called snowflake mollies) is a selection form of sailing mollies.

Keep them better in groups or in pairs.

This fish lives mainly in the upper and middle layer of water, loves the water space and light.

The light day of mollies should be at least 12-13 hours. It is useful for fish, if at least a couple of hours a day lighting is natural, but if there is no possibility, then you can do without it.

Of course, she also needs natural shelters: thickets of plants, snags, decorative ornaments that can serve as a refuge.

Mollies feed on all types of dry and live food.

The only condition that helps to maintain the activity and health of these fish is that they definitely need plant fiber.

Therefore, along with others, use vegetarian feed, plant in the aquarium plants with soft leaves, which the fish can eat. You can also feed them in small portions of chopped boiled vegetables.

Another important point in the content of mollies: at home, they live where the river water mixes with the sea water, and therefore they like hard water. If you only have mollies and placilia in your indoor pond, you can even add some salt to the water on purpose.

If other fish also live with them, then of course you should not do this. But in the case of illness or quarantine, the fish can be deposited in an aquarium with salted water – so it will come back to normal faster.

The name “molliesia” originated from the genus name – Mollienesia. The natural range of these fish is fresh and slightly saline waters of Central America. Wide mop mollies live mainly in reservoirs with standing waters or small currents in southeastern North America.

The natural color of these fish is very colorful, mostly dominated by yellow-gray and spotted species.

For the first time these fish appeared in Europe more than 150 years ago, it was the spotted mollies that became the favorites of aquarists. Then, the popularity of the hybrid form, which acquired the name black mollies, gained popularity.

Black mollies were obtained as a result of breeding in the United States, and in the early forties of the last century they were bred in the territory of the Soviet Union.

In the sixties, it became fashionable to keep other mollies – the lira mollies. Which, in turn, were also bred by selection, as well as fish with a short disk-like body.

At first glance, domesticated mollies resemble swordtails. But mollies have wider tail fins and more dorsal fins.

The females of these fish are slightly larger than the males. With good care and favorable conditions, females grow up to 8 cm, and males up to 6 cm.

Wild representatives of this species and a half times more. In addition, the fish living in the wild have a somewhat oblong and more rounded body, they are somewhat reminiscent of the placium.

Even an inexperienced eye can distinguish females and males; the males have a long process at the anal fin – gonopodiums.


Mollies are viviparous fishes, they are loved for a magnificent and bright color. For example, in sailing fish of this species of extraordinary beauty, a gray body with an olive sheen, on which, like a brush, transverse stripes and nacre specks form dark points.

Aquarium species of mollies are the result of the cultivation of North American species, or their selection. Despite a number of differences, all the fish have common qualities.

  1. Females of all types of mollies are an order of magnitude larger than males: for example, Velifer’s mollies reach 18 cm in length, female Latipeny 12 cm, sphenops 8 cm. Sexual dimorphism is expressed: except for the difference in body size, the anal fin of a male cone-shaped (genopod) in females it is fan-like. All the mollies females are viviparous fishes that bear fry, bringing them to the light ready for full-fledged life activity.
  2. Pet shops sell different sphenops and latexes, how many of them are actually bred – only experienced ichthyologists know. Black mollies are common. Sometimes among their brood there are other forms — spotty, with light scales, or blue-green skin. New species – fork mollies, which has a “carved” tail fin, elongated in the upper and lower parts; scarf molly, in which the dorsal fin is long and elongated.
