Aquariums with fish are often found at home and in cafes, offices and shops. Aquariums are a great decoration of the room and an excellent way to communicate with animals.

The content of aquarium fish of different breeds is not significant, but different. Ground rule content of any aquarium fish is the use of specially prepared water. Most domestic fish feel most comfortable in water that has been settled for at least 7 days. In no case can not be used for an aquarium ordinary water from the tap - it can destroy all its inhabitants.

Goldfish Content

Goldfish is one of the most popular aquarium fish. Its bright colors and beautiful fins like both adults and children. The content of goldfish in an aquarium is considered simple and does not take much time. In order for goldfish to be healthy and feel good in an aquarium, they need the following conditions:

  • a large aquarium, at least 100 liters;
  • powerful filtration and aeration system;
  • regular replacement of water (in small parts);
  • small population density of goldfish.

In an aquarium with goldfish it is recommended to plant the plants. They contribute to a good ecological situation and are a kind of feeding for fish. The only disadvantage is that goldfish in a short time eat up all the vegetation in the aquarium. Therefore, it is necessary to plant new plants often enough.

Replacing the water in an aquarium with fish should be carried out once a week, and not to replace the entire volume, but a small part of it. Also, the owner should control the degree of contamination of the filters and clean them as needed.

The content of parrot fish

Parrot fish love warm water, up to 30 degrees. Like other species, they need aeration and regular filtration of water. An important rule of keeping parrot fish in an aquarium is regular partial replacement of water - 10% of the total volume 2 times a week. In the aquarium should be planted plants and make special caves, shelters, secluded places.

The remaining rules for the maintenance of a parrot aquarium fish do not differ from the general recommendations for the maintenance of aquarium fish.

Cockerel fish is popularly called "fighting fish". She received this nickname because of her frequent fights with other inhabitants of the aquarium. In this regard, many are afraid to move the cockerel fish in the aquarium with other fish. In fact, these concerns are completely groundless. The cockerel fish only fights with individuals of its own species, and is indifferent to other residents of the aquarium. Therefore, keeping these fish in an aquarium with other fish is safe. And stunningly bright large fins delight the eye of everyone who is near the aquarium.

Males feel comfortable in small aquariums with moderately warm water - no more than 25 degrees. For these fish it is important to ensure the proper situation in the aquarium - the presence of plants, soil. An aquarium with several individuals should be divided by partitions - the cockerel fish need "their own territory". As many plants as possible should be planted in the aquarium - they carry out natural water filtration and aeration. Also, create a more natural environment for fish in the aquarium.

Another important rule for keeping cockerel fish in an aquarium is to exclude any sharp objects from it. The sharp corner or the edge of the decorative aquarium figurine can cut off the luxurious fins of a fish.

Swordsmen know everything, even those who have never encountered the aquarium world. The Sword bearers gained such fame due to their wide distribution (one can say that they were part of the set of every young aquarist of the former USSR), as well as thanks to a special sign - the tail fin in the form of a sword. Actually, it was for this tail that the Swordtails got their name.

Maintenance and care of the swordtails

Contain Swordsmanin in aquariums it is easy enough because of their unpretentiousness to the composition and volume of water. One pair must be at least 6 liters of water. Aquarium needs a long, with a lid (can jump out of the water).

Optimum water parameters: temperature 22-24 ° С, dH 5-20 °, pH 7.0-8.0. Requires strong aeration and filtration. Once a week it is necessary to replace water by 1/3 of the volume. It is recommended to add sea or table salt to water: 1 tbsp. 10 liters of water.

Thick thickets of small-leaved plants (for example, notched elodea, cabomba, wallisneria) are perfect for an aquarium with swordtails. But free space for swimming fish must also be present. On the surface of the water, you can let ricci.

As neighbors fit any peaceful fish. There are conflicts in the group between males of swordtails, so it is necessary that there are more females than males. In this case, the males must be either one or more than three individuals - aggression is sprayed, and not directed directly at each other between the two males.

Breeding swordsmen

Swordtails belong to the family of viviparous. The female at a time is able to give life from 15 to 100 fry, and even more. The number of juveniles born into the world depends on the age and size of the mother, as well as on the conditions of her life. For successful breeding, the pregnant female is deposited in a separate aquarium before birth. So that the fry born to avoid the teeth of an adult female, small-leaved aquatic plants should also be placed there to create life-saving algae thickets in a small pond where it is so good to hide from danger. Breeding will not require any special care from the aquarist.


It will be enough only to isolate the female for the time of childbirth from the rest of the aquarium, and after the childbirth return it to its usual environment, leaving the swordtail children to develop independently. By the time of birth, fry are completely formed for the beginning of independent life. As soon as they were born, they immediately begin to tirelessly master the space of the aquarium and actively feed. Kids are almost omnivorous, but it is preferable to give them daphnia and cyclops. With proper feeding, the fry grow rapidly, by 3-4 months they already acquire a “sword”, and puberty occurs in 4-6 months.

and etc.

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.

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, however, 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

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.

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.

Aquarium fish CONTENT AND CARE

aquarium fish

For aquarium fish to be healthy, they need clean water, food, and, of course, attention. A variety of decorative little things, such as corals, sunken ships or shells are just an ornament, but not a necessity.

The most important thing in care and maintenance is the replacement of water in due time. The main cause of diseases aquarium fish - dirty or substandard water. When your pets have a bad appetite or they are pressed to the bottom, these are clear signals that it’s time to change the water. The water that you will add must be at the same temperature as the aquarium one. It is also necessary that the hardness of the topped-up water be the same as the aquarium one. The same applies to acidity.

For better water use aquarium filter. But also do not forget that the filter itself needs timely purification from contamination. To improve the quality of water and its chemical components, you can purchase additives or beneficial bacteria. But be sure to consult before buying a seller in the store.


The most important thing in feeding aquarium fish is that they should not be overfed. This will advise you in any store. Since the fish are cold-blooded, they need a lot less food than we do. Consequently, it is simply necessary to feed them regularly and in no case should one throw any excess food into the water, since nobody will eat it, and the remnants of food will only pollute the water. Fry feed twice a day, adult aquarium fish less often.

Having bought the fish for the aquarium, first hold them apart from the others, as they say "quarantined", in order to find out that they do not get sick and, therefore, are not a danger to the rest of the inhabitants of the aquarium.

No need to catch aquarium fish with your hands, use the landing net designed for this. Since your pets will be under severe stress, it’s also easy for them to damage the mucosa.


It is also necessary to have a temperature-controlled heater and aquarium lighting. For night time, choose a dim light for a comfortable and not abrupt transition to darkness so that aquarium fish can “go to bed”.

Do not forget about the necessary thing - the ground, it maintains the biological balance and many inhabitants of the aquarium simply adore it. Also, the soil is used for the reproduction of beneficial bacteria and is necessary for aquarium plants.

One of the important rules - the fish for the aquarium should be grouped only so that they can get along with each other. That is, predatory fish must be strictly with the same predatory, schooling flocks contain, and pair - in pairs.

I hope these tips will provide you with invaluable assistance in the care of these wonderful inhabitants, bringing us peace and tranquility.


How much to feed the fish?

I would say that the majority of aquarists feed their fish correctly, but too often they have to see how over-feeding turns the jar into a foul-smelling swamp or fish that is so overwhelmed that they forget how to swim.

And it is easy to understand why this is happening. There is no specific standard, and feeding fish may not be an easy task for a beginner. The fact is that with the fish, we most interact during feeding. And so you want to feed them a little bit more.

And a novice aquarist feeds the fish, every time he sees that they are lonely asking for feed from the front glass. And most of the fish will ask for food even when they are about to burst (this applies especially to cichlids), and it is so hard to understand when it is already enough.

And yet - how often do you need and how many times to feed aquarium fish? Fish should be fed 1-2 times a day (for adult fish, fry and adolescents should be fed much more often), and with the amount of food that they eat in 2-3 minutes. Ideally, no food would get to the bottom (but do not forget to feed catfish separately). We will immediately agree that we are not talking about herbivores, for example, ancistrus or brocade catfish. These eat almost around the clock, scraping algae. And do not worry, it is not necessary to carefully monitor each time if they ate, just a couple of times a week look.

Why is it so important not to overfeed the fish? The fact is that overfeeding negatively affects the state of the aquarium. Food falls to the bottom, gets into the ground, rots and starts to spoil the water, while serving as a nutrient base for harmful algae.
At the same time in the water accumulate nitrates and ammonia, which poison the fish and plants.
Dirty, algae-covered aquariums with sick fish are often the result of overfeeding and dirty water.


Aquarium fish What to feed?

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, the blurred eyes).

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