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.

For all living creatures, including fish, the most important condition for existence is the ambient temperature. It affects not only the environment, but also the chemical and biological processes that take place in animals and plants.

As for aquariums, there should be about the same temperature in all layers, otherwise both plants and fish can suffer. Since the top layer of water is always higher than the bottom, therefore, the temperature should be measured not only on the surface of the water, but also on the ground. The regulator of the temperature of the water in the aquarium can be purchased at the store, and you can make it yourself, but you cannot do without it when breeding fish.

Because some temperature changes for many fish species can be deadly.

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.

For all aquarium fish, the water temperature in the aquarium is important, so you need to monitor it periodically. For most of the inhabitants of the aquarium, a temperature range of between 22 and 26 degrees is suitable.

Discus and labyrinth fish need a temperature of 28-30 degrees, and goldfish – from 18 to 23. Of course, they can live at elevated temperatures, but over time not to avoid disease: most often in animals dysfunction of the swim bladder occurs.

Ensure that there are no sudden changes in temperature (more than 4 degrees) in the aquarium. A smooth change is acceptable, but by no means drastic.

However, jumps occur quite often, and especially for small aquariums, the capacity of which is less than 60 liters. This is due to the fact that a small amount of water heats up quickly, but cools down for a short time. So, for example, a window leaf that is open for a few minutes can cool the water very much, and aquarium fish will get chilodonellosis or a bacterial infection.

If there is no thermometer in the aquarium, the owner will not be able to find out about such jumps in temperature, and the symptoms of the disease may appear very late.

In order to maintain the optimum water temperature in the aquarium all the time, a thermometer and a heating pad are needed. A thermometer should be in every aquarist. It should be located in the aquarium so that you can clearly see the temperature.

This is important because the faster a person sees the changes and takes the necessary actions, the less the inhabitants of the aquarium will suffer. Recently, the choice of thermometers is huge, so everyone can choose a convenient one for themselves.

To maintain a constant temperature in the aquarium, you need a heating pad that heats the water to the desired temperature and then automatically turns off. If it has a high level of power, then residents of the aquarium are not afraid of drafts, temperature changes, or airing.

If you do not have the opportunity to constantly wonder what the temperature of the water in the aquarium, then you need a heating pad. The main thing is to choose a quality one, because otherwise it may not always respond to temperature drops, not turn on, or, on the contrary, warm water, not turn off, and your fish can boil.

To avoid this, the heating pad must be changed periodically.

If you really care about your fish, then purchase only proven products for them; Do not rush to choose, consult with experienced aquarists, read reviews about the product and only then make a purchase.

Water temperature is one of the defining indicators for the life and health of the inhabitants of the aquarium. What temperature should be in the aquarium depends, first of all, on the species that you plan to maintain and breed.

Each species of fish or amphibians has its own optimal conditions of detention. You should familiarize yourself with them before purchasing the first copies and placing them in a new aquarium.

Such a preliminary acquaintance with one type or another will allow you to choose fish that match the requirements of the conditions, which then get along well and seamlessly with each other.

Most of the most common and popular fish species will feel good in aquariums with a water temperature of 22–26 ° C. Therefore, setting the temperature of the water in the aquarium for guppies, the scalar and swordtails need to stay within these limits.

Some breeds of fish, but not too much, love the water warmer. Usually for labyrinth fish and dikus it is recommended to heat the water to 28–3 ° C. Goldfish is another matter.

The water temperature in the aquarium for goldfish is set in the range of 18–23 ° C. In warmer water, their life expectancy is significantly reduced, they can get sick.

We should also mention the temperature of the water in the aquarium for the red-eared turtle, since the content of these amphibians is becoming increasingly popular. Turtles love heat and feel best in water heated to 25–28 ° C.

Continuous monitoring of the fluctuations in the temperature of the water in the aquarium will allow you to notice strong changes in time and respond accordingly: heat the water to the required level or, conversely, cool it. Therefore, the acquisition of a thermometer for an aquarium is simply a must-have item for its arrangement. After all, water, especially in small aquariums, may cool down and heat up very quickly, and this will not be noticeable to the eye until the fish start to behave sluggishly or do not die at all.

Now you can also purchase special heaters for the aquarium, which not only heat the water, but can also maintain the same temperature during operation. If the aquarium is not equipped with a similar heater, then it can be purchased separately. When it is necessary to lower the temperature of the water, it is necessary to pour a small amount of it, and in its place to pour water at a lower temperature.

However, do not immediately replace too large amounts of water, as sudden changes in temperature will adversely affect the health of the fish. Better after a while to repeat the operation again.

Mollies is one of the most beautiful viviparous fish of the family. Breeders worked well and brought out different forms of fish with different fins. Black fishes are very popular.

The length of the female body is about 8-10 cm, the male – 6 cm. Often unscrupulous sellers persuade newbies to buy a fish, claiming that mollies are unpretentious and can live in any conditions, but this is not so.

These charming fish love space, bright lighting and warm clear water.

One fish needs at least three liters of water. Keep mollies desirable groups. These peaceful fish calmly relate to other inhabitants of the aquarium.

For the proper development of mollies constantly need fresh water.

Once a week, a quarter of the water is changed to fresh settled. The filter should always work.

It is worth mentioning that the water should be a bit hard. To do this, put a piece of marble in the aquarium.

What else does mollies love? Water temperature should not be lower than 26 ° C.

In hot summer, temperatures can rise to 34 ° C, but the fish are not afraid. Much harder they suffer lowering and temperature drops.

In nature, mollies live in brackish bodies of water. They can often be seen in aquariums, along with sea fish, but in fresh water, death awaits them.

Of course, the fish will not die immediately, but it will be bad to grow and hurt. Per 100 liters of water must be diluted with about 150 grams of sea or ordinary salt.

In no case can iodized Extra salt be used.

Often aquarists destroy their mollies, giving them only animal food. Young and adult fish need plant food.

They can be given scalded cabbage leaves and dandelion. Fishes enjoy eating filamentous algae and generally love aquariums planted with aquatic plants. Adult mollies are fed once a day.

With good care, these beautiful fish can live in an aquarium and please their owner for about eight years.
