Temperature in the aquarium

maintenance, care, compatibility

In natural waters, fish are more accustomed to temperature changes, since this is their natural habitat. Yes, and the area of ​​water space is such that warming or cooling water occurs gradually.

So the fish here have time to adapt.

With aquariums, the situation is somewhat different: the smaller the volume, the more tangible the temperature jumps. And the more likely the development of “fish” diseases.

Novice aquarists should consider this feature and know what the normal water temperature in the aquarium is.

In one aquarium, it is desirable to keep the fish, accustomed to certain conditions of life, with the same features of the body. Despite the fact that all the fish – cold-storage, some of them live in cold waters, others – in the warm.

  • Fishes accustomed to warm waters can be divided into 2 species: consuming a small amount of O2 and those who need large reserves of oxygen.
  • A cold-water type of fish is only called that – they calmly withstand different temperatures, but they require a large amount of oxygen in the water.

For beginners aquarists can recommend small aquariums with low-breathing warm-water fish. In large tanks, it is better to initially contain the cold-water inhabitants of aquariums.

What should be the temperature of the water in the home aquarium

To the inhabitants of domestic ponds was comfortable, the temperature there must be at a certain level. And before you run the fish in your aquarium, you need to know what the natural conditions of its existence are (and most of the aquarium inhabitants come from the tropics).

The gradation of temperature parameters can be represented as follows:

  • The optimum temperature of the aquarium, which is suitable for most fish, ranges from 220 to 260C;
  • water temperature in the aquarium below the minimum optimum is no longer acceptable to warm-water fish;
  • a rise in temperature above 260 is permitted by 2-40 ° C if it is gradual.

Changes in temperature in a domestic pond to one side or the other from the optimal parameters are more easily tolerated by aquarium inhabitants if the water is sufficiently enriched with oxygen. The most difficult thing will be to fed fish – they need more air at any temperature drop.

But with a sharp cooling, the fish will suffer and hungry.

There are no specific numbers to suit each aquarium, as the temperature depends on factors such as its inhabitants, plants, and the chosen maintenance mode. The temperature range for most fish is from 20 to 30 ° C, however, for each individual species of fish should maintain an optimal temperature.

So the best constant temperature range in an aquarium for guppies varies between 24-26 ° C, but some deviations are allowed – 23-28 ° C. At the same time, if the temperature drops below 14 ° C or rises above 33 ° C, then the fish will not survive.

For catfish, the temperature in the aquarium is optimal in the range from 18 to 28 ° C. However, catfish – unpretentious fish, so easily withstand significant deviations from these limits, but for a short time.

The temperature in the aquarium for scalar basically has a large range. The optimum is 22-26 ° С, but they will easily transfer the temperature drop to 18 ° С, but it is necessary to lower gradually, without sharp drops.

The optimum temperature in the aquarium for swordtails is 24-26 ° C, but since these fish are not demanding enough, they will calmly endure a temporary decrease to 16 ° C.

The recommended temperature in the aquarium for cichlids should be in the range of 25-27 ° C. Sometimes it can be increased by 1-2 degrees, but no more, since for most fish of this species the temperature of 29 ° C is fatal. At the same time, a significant decrease in temperature even up to 14 ° С can be transferred by fish quite calmly (of course, not for a very long time).

The water temperature in the aquarium should be constant. Its fluctuations during the day are allowed within 2-4 ° С.

Sharper drops can have a devastating effect on the inhabitants of the aquarium.

Everyone knows that the temperature of the water in the aquarium corresponds to the temperature in the room. Therefore, when for some reason it becomes excessively hot or cold in the room, certain measures should be taken.

In the hot season you will need knowledge of how to lower the temperature in the aquarium. There are several ways to do this:

  • use of a special refrigerator for the aquarium;
  • installation of air conditioning in the room, which will maintain a certain temperature;
  • use of ice or cold accumulators.

In the case when it is too cold in your apartment during the cold season, you should know how to raise the temperature in the aquarium. The simplest version of the heater is a hot water heater.

It must be placed between the heater and the side wall of the aquarium. But this is an emergency way of heating water, as it will not work for a long time to maintain the temperature of the water.

Each of the ways to increase or decrease the temperature of the water is good in its own way, and you should choose a particular one based on your specific needs.

The life of all living organisms, including humans, is determined by a number of environmental factors. Among physical factors, temperature plays the greatest role, affecting the flow of all metabolic processes within an object.

That is why the observance of the correct temperature regime will provide your pet with comfort and long life.

The optimum temperature in an aquarium can vary within very wide limits for different organisms of even one family, therefore we cannot separate each one individually. But to discuss the temperature optimum for the most common inhabitants of aquariums, we are quite capable.

Temperature in a guppy aquarium

Guppies are not demanding fish and can easily live in a regular can, but for nurturing beautiful and healthy pets it is necessary to provide them with space and regular aeration of water. Regarding temperature, guppies are also labile, the range from 18 to 30 degrees is suitable for vital activity, but the optimum is 24-25 degrees.

The temperature of the water in the aquarium for the angelfish

Angelfish are warm-water fish, so the fact that for guppies is considered an extreme temperature for existence, for scalar still quite a pleasant atmosphere. Anyway, these cold-blooded fish are most active at 28 degrees, while at 24-25 their growth and development begins to slow.

Temperature in a cichlid aquarium

Cichlids are very sensitive to temperature fluctuations. As a result of hypothermia or overheating, they not only stop the development, but also lose the opportunity to develop their remarkable color, which is why the temperature in the aquarium for such fish should be a constantly adjustable parameter.

The optimum is 25-27 degrees, but for Tanganyik cichlids, this temperature should not exceed 26.

The temperature in the aquarium for barbs

Barbus – fish is simple to keep. Barbs are easy to feed, breed and maintain conditions optimal for their existence.

The optimum can be considered the temperature in the range from 21 to 26 degrees, while it is desirable that the water is well aerated and there was a slight flow.

Temperature in a catfish aquarium

More than 1000 species of fish from different families are called somami, therefore it is not easy to determine a single temperature range. Usually, catfish love temperatures closer to room temperature. in the range of 22-25 degrees.

For stimulation of reproduction, the temperature is usually increased by 2-3 degrees.

What temperature should be in the aquarium and how to maintain it

In order to provide aquarium inhabitants with comfortable conditions, it is necessary to strictly observe the temperature conditions that will be optimal for them. For each type of fish has its own comfortable temperature habitat.

The question “How does a little girl retrain to go to the tray (she is 4 months old)? “- 3 answers

Some fish need relatively cool water, others are more thermophilic. This must be taken into account when purchasing an aquarium, as well as when selecting different types of fish.

Beforehand, one should make sure that they can coexist at the same temperature.

Optimum temperature for different types of aquarium fish

For the vast majority of ornamental fish, the optimum water temperature in an aquarium is from 22 to 26 degrees. The first is to focus on this temperature. However, there are exceptions.

Some fish species prefer warmer water in the aquarium. These, above all, include some species of labyrinth fish and all discus.
For goldfish, lower water temperatures are more comfortable. The ideal temperature for them is from 18 to 23 degrees.

These fish for quite a long time can live at a higher temperature, but later it causes them to develop various skin diseases.
Sharp temperature fluctuations of more than 3-4 degrees should be avoided. A smooth change is quite acceptable, but jumps that occur within one day, or even several hours, are very undesirable.

This often happens in small aquariums – less than 50 liters. Such small volumes are very sensitive to changes in ambient temperature, they cool down quickly and heat up quickly.
A pane open for several hours during the cold season can cause a change in temperature in the aquarium by several degrees. In this case, the fish can catch a cold.

After which they will need special treatment. In the natural habitat of such temperature fluctuations do not exist, since large masses of water rather slowly cooled and heated.

Therefore, fish are not adapted to extreme temperature fluctuations, and apart from diseases, this can cause them stress.

To maintain a constant water temperature in the aquarium, heaters of various types are used. Temperature control is controlled by thermometers.

If the temperature fluctuations in the room exceed 4-5 degrees, it is advisable to use heaters with automatic temperature control, which allows you to maintain a constant preset temperature.
It is important to evenly distribute the heat from the heater to the aquarium. To do this, the heater must be washed with water or air bubbles coming from the filter and compressor, so that the heated water spreads throughout the tank.
