maintenance, care, compatibility

For a start, think carefully about where you put your home aquarium, where the fish will live. The choice of the shape and size of the tank depends on the location.

It is considered that the maintenance of a spacious aquarium does not take long to clean. Caring for him is much easier than small.

A large tank can contain a large number of different fish that are compatible with each other. Also do not forget about the devices, without which the functioning of a modern reservoir is impossible.

Compressors, filters, lighting devices, decorations will provide the highest quality care.

Another issue that bothers aquarists – the choice of pets. For beginners, small and unpretentious fish are suitable that can survive the host’s small errors.

Contrary to popular belief, goldfish and cockerels are not easy-to-keep fish. They will have to spend more time with them.

Goldfish leave behind a lot of waste, and you have to clean up more often in the aquarium. Males are sensitive to changes in water parameters and infections.

Guppies – one of the most unpretentious fish, belong to the family Petsiliye. They have a bright tail, like the whole color of the body.

The size of the females is 6 cm in length, the males are 3-4 cm. These are herbivorous aquarium fish, which need to be eaten more green. They love clean, oxygenated water.

Another unpretentious fish – it’s cichlids. There are African and South American species.

For the beginner, omnivorous and herbivorous tsikhlovye fish are suitable. Predatory species are incompatible with other fish, and are quite dangerous.

Other types are very friendly and quick-witted, they can live alone or in pairs.

Caring for an aquarium is like cleaning the house, the same simple rules for staying healthy and clean and regular. In this article you will learn how to properly care for a home aquarium, what important things there are and how often to do it. Why do you need to siphon the ground?

What cleaners can I use? How to wash the sponge filter? Why and how to change the water in the aquarium?

You will find answers to these and other questions.

None It is very important to wash the filter with water alone.

And it is also important that the water was from the aquarium. Tap water contains chlorine, which kills harmful bacteria in the water.

But he does not know how to understand and also kills the beneficial bacteria living in the internal filter.

Separated water can be used. But here again, another water with a different hardness, acidity and temperature, and it can affect the colony of bacteria.
So the best method is to draw water from the aquarium and rinse the filter and its contents in that water.

Ideally, even the container in which it is washed should be used only for the needs of the aquarium, if you wash floors from it, then the chance that the chemistry will remain in the container is quite substantial.
And it is important not to wash everything to shine, just rinse well.

Despite the fact that some aquarists do not substitute water for years and say that they have everything ok, regular water changes are vital for an aquarium.
The amount of water that is worth changing varies from the conditions in your tank, but on average 10-20% per week is a normal amount for any tropical aquarium. Herbal plants or densely planted aquariums need a 10-15% change every two weeks.

The main task of the substitution is the removal of nitrates and ammonia, and the recovery of mineral balance. Without a water change, your aquarium will look good for a while, but only due to the fact that negative factors gradually accumulate.

For a long time, nitrates will accumulate, and the water becomes more and more acidic. But once the balance is broken and the aquarium will turn into a swamp.

How to care for fish in an aquarium :: aquarium fish and care for them :: aquarium fish

The need for careful and systematic care of the aquarium and the fish living in it is obvious: feeding animals, periodically changing the water, cleaning the aquarium, inspecting it and checking the operation of the equipment necessary to keep the fish in the water. But that is not all!

The question “opened a pet store. Business is not going. What to do? “- 2 answers

1. Goldfish
One of the most popular aquarium fish are golden fish. At first glance it may seem that these fish are unpretentious in the care, but it is not.

If the care of them is inadequate, then they will live only 3-4 days. Since goldfish grow in length up to 15 cm, then the aquarium should be selected appropriate: its capacity should be at least 50 liters per fish. For the proper maintenance of these animals, an appropriate soil is needed: the fact is that these fish simply love to rummage in the soil.

Plants for such an aquarium need to pick up large-leaved, but you need to be prepared for the fact that exotic fish quickly spoil them with their feces. The aquarium itself should be spacious, bright. Do not forget about the appropriate coverage and filtering.

Goldfish are gentle creatures, so you should avoid shells with sharp sides.

2. Guppy
These fish will not cause much trouble in their content – they are not picky. Guppies live and breed at a water temperature of + 20-25 ° C, but they may feel fine even at + 18 ° C.

In order for the fish not to lose their color, you need to put the aquarium so that in the daytime and in the evening direct sunlight falls on it. It should be borne in mind that guppies do not like polluted water, preferring that its replacement be partial. Guppies easily get along with other non-predatory fish, preferring the top layer of water space.

These fishes swim in flocks one after another. The food for these cute creatures is dry daphnia, as they are not picky about food. For keeping guppies suitable aquarium in 50 liters.

3. Petushki
These fish, if necessary, can breathe atmospheric air, so care for them will not cause any special problems. The cockerel can grow up to 7 cm. Males have magnificent fins, while females are not developed.

For the maintenance of cockerels, you must purchase an aquarium from 60 liters. As the soil you need to use coarse sand, small and large pebbles. Soil must be decontaminated. The central part of the aquarium should be free from plants: the entire aquarium flora is located on the sides.

It is recommended to add a little decorative snags and pebbles to the bottom. Everything is pre-processed.

Food for cockerels plays a big role in the brightness of their color. For example, dry food, suitable for the same guppy, for males will be a real poison!

Therefore, the diet of these fish should include only live food, egg yolk, small pieces of meat.

The cockerel or betta fish (Latin Betta splendens) is one of the most popular aquarium fish.

Natural habitat – freshwater ditches, rivers, streams of Southeast Asia. Often found in paddy fields. For the first time the fish was noticed by residents of Siam at the beginning of the XIX century. The “stranger” was distinguished by aggressive behavior towards his relatives.

Later, the fighting fish was transferred to the imperial court, where it was examined by European scientists invited to the country. Residents of Siam used the cockerel in the “fish” battles: the males vehemently demonstrated their strength, but no deaths occurred.

The genus Betta charges more than 70 species, and the Betta splendens cockerel is one of them. There are 6 more types of betta, which are not related to a particular type. The genus Betta is divided into 2 groups: the representatives of the first build a foam nest, the second – incubate the eggs in the mouth.

Today, aquarium betta ordinary are full of a variety of shapes and colors, so it is important for them to provide constant care.


Cockerels are small aquarium fish; in captivity, their body length reaches 4-6 cm, males are a centimeter more than females. In Betta splendens (common cock), the body color is green-olive, with dark spots or stripes. The fish mimic the environment, so the color of scales may vary.

During spawning and aggression, the body becomes bright, at rest it is faded. In the wild cockerel, the fins are short and round.

Now there are many breeding forms of these fish, which differ in color scales and fins.

As a representative of the contract. Labyrinth fish, the cockerel is a double-breathing fish, can breathe like gills, and there is atmospheric air. It captures air into the labyrinth channel, where it dissolves.

This is a big plus, because in aquarium with cockerels aeration is not necessary, in this case it is much easier to care for a pet in an aquarium. They can be kept in “Spartan” conditions, although this is undesirable.

Caring for them will not cause any trouble even to a novice in aquarism. If the aquarium water temperature, acidity, purity are maintained at a normal level, the pet will live longer.

Watch the video story about the cockerel fish.

Cockerel content is available at home, it is possible even in a 3-liter jar. For two individuals and more will need more capacity. Like all fish, cramped – only to the detriment.

Fish will be very comfortable in a rectangular and spacious aquarium. It is not recommended to keep more than one male in the aquarium (except for the black cockerel species).

Between them there are often disputes that already speak – even between the female cockerels there were fights. The result – bodily injuries, dangling fins.

If you have nowhere to settle two males – choose a large aquarium of 50-100 liters or more. You can put a partition in it, so the territory will be divided.

Also, the fish have bursts of aggression, when there is a change of water or a female appears.

They are not easy to maintain with other types of fish – some are not averse to tear off the beautiful and long fins. The males themselves can attack peaceful fish with veil fins. Good aquarium neighbors – danios, speckled catfish, cardinals.

Compatibility with barbs is controversial, it is possible if you find a fish with D-shaped, short fins. The males quickly get used to the neighbors, and the eviction of one of them can lead to stress.

The Betta splendens fish is a tropical species, so it is recommended to settle in aquariums with infused and warm water: water temperature 24-27 ° C, ph 6.0-8.0, hardness 5-35 dGH. Once a week it is necessary to replace 25% of water with fresh.

Aeration is optional.

They can be kept in a nano aquarium, in glass containers. But think carefully, will it be convenient for a small fish in a crush? Indeed, in a limited space there is no possibility to plant the plants, install snags, decorations, shelters.

To provide the fish with proper care, you need swimming space, safety and cleanliness. So you can put a filter in the aquarium so that your pet does not get sick. Lighting is necessary, in the tank you can put an LB lamp of 0.4 W per 1 liter.

At night, the light is required to turn off.
