The optimal temperature for fish in an aquarium and how to maintain it
Fish are cold-blooded animals, the full activity of which is ensured by the constancy of the water temperature in the habitat. The body temperature of the fish exceeds the water temperature by about 1o.
Changing the temperature of the habitat directly affects the health of cold-blooded organisms.
All holders of aquarium fish should understand that the life of their pets directly depends on the temperature conditions in the aquarium. What should be the optimal water temperature for different ornamental fish, and how many degrees should be reflected on the scale of the thermometer so that each fish feels healthy?
About temperature limits for warm and cold-water inhabitants of reservoirs
The fluctuation of aquarium temperatures is possible, it is even permissible within certain limits. A slow change of 2-4 degrees will not lead to tragic consequences. If the aquarium is placed on the window sill or near the window, then depending on the time of year, the temperature will change in it.
Aquariums should not be installed near batteries and other heating systems, even heat-loving fish will not survive strong heating.
What can be the water temperature for different fish? You can set the average range of oscillation for cold-water and warm-water fish, but these are not settled in one aquarium – this is prohibited. How many degrees should be acceptable temperature limit, which would be acceptable to all:
- 24-26 degrees Celsius
See how in the heat to lower the temperature in the aquarium.
Temperature fluctuations should not exceed three degrees! Before settling in the fish aquarium, find out what the average temperature range of their content.
It is also worth controlling to above water – this is important for labyrinth fish that breathe portions of air from the surface. As an example, you can explore the content of the labyrinth fish gourami, which, breathing the air 5o below the water, can suffocate and die.
Just for them, the cold air is critical.
It is recommended to install a thermometer and thermostat for water and air to keep the gourams. Water should evaporate in a minimum amount, and to water above water should be similar to that in a pond.
If gourami inhale too hot or cold air, the untreated oxygen enters the labyrinth channel, clogs it, and the fish suffocates.
Gourami are temperature sensitive because it affects the breeding cycle. Warm water is an incentive to spawn, in this period it is appropriate. If it is warm all the time, in the body of gourami the processes of vital activity slow down, the protective functions of the body are reduced.
At an incorrect temperature, sex cells are not produced, and gourami will not give offspring. Surviving fry in the wrong aquarium water conditions die.
Allowable temperature for gourami in water: 23-26o, to air on the surface – 26-28o.
Is it true that cichlids tolerate different temperature ranges?
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 in a fish tank – Frequently asked questions by aquarists
Does this mean that the temperature of the water directly affects the fish?
Water temperature affects the speed of physiological processes in the body of fish. For example, in winter, the fish of our water bodies is inactive, since the level of metabolism drops significantly in cold water.
At high temperatures, water retains less dissolved oxygen, and for fish it is very important. That is why in the summer we often see fish rise to the surface and breathe heavily.
Rapid changes in temperature aquarium fish suffer poorly, this is one of the reasons from which newly acquired fish die. In order for fish to get used, they need to be acclimatized.
Simply put, the higher the temperature of the water, the faster the fish grow, but they also age faster.
How sensitive are fish to temperature extremes?
As already mentioned, warm water retains less oxygen, and the fish begin to experience oxygen starvation. They begin to choke, and the first thing to do is turn on a powerful aeration or filtration to increase the movement of water and metabolic processes in it.
Next, you need to put in the aquarium a bottle of cold water (or ice, if you were preparing for this situation), or replace some of the water with fresh water with a lower temperature.
Well, the simplest and most expensive solution – air conditioning in the room. And in more detail about all this read in the material – hot summer, lower the temperature.
And the simplest and most inexpensive is to install 1-2 coolers so that they direct the air flow to the surface of the water. This is a proven cheap way to cool the temperature in an aquarium by 2-5 degrees.
And what tropical fish can you keep in cold water?
Do I need to change the water in the aquarium with water of the same temperature?
Yes, it is desirable that she was as close as possible. But at the same time, in many species of tropical fish, the addition of fresh water with a lower temperature is associated with the rainy season and the beginning of spawning.
If you breed fish in your tasks is not included, it is better not to risk and equalize the parameters.
For sea fish, it is definitely necessary to equalize the temperature of the water, since sea water does not have sharp changes.
You can read more about acclimatization by clicking on the link. But, in short, the fish actually needs a lot of time to get used to the new conditions.
Only water temperature is critical when landing in a new aquarium, and it is desirable to equalize it as much as possible.
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.
Angelfish require compliance with the rules of the content, and especially – the temperature. Hypothermia scalar leads to disease and death – as well as temperature jumps when changing water.
In order for the pet to be healthy and beautiful, you need to strictly monitor the temperature in the aquarium.
Angelfish came to us from their waters of South America, where there is warmth, so they also need a heater in the aquarium.
The temperature must be maintained at 24 ° -27 ° C. Some species of fish require a slightly higher temperature: for example, black scalars are cold at temperatures below 27 ° C.
The optimal temperature for scalar spawning is 30 ° C. Low temperatures will slow down the process and possibly ruin it.
Aquarium for scalar should be large. It is necessary to create a stream of water in it, since in nature the scalar lives in rivers.
A lot of plants and enough space – that’s what you need for an angelfish.
Be sure to saturate with oxygen! The aquarium should be well lit and stand in a quiet place, as loud noises cause fear and stress to the scalar, which can lead to loss of color.
It is not recommended to keep the angelfish with small fishes, just as with the territorial ones that are too large and too mobile.
The temperature for the scalar should be maintained at the same level. A short-term decrease in temperature these creatures can withstand, but it is better not to risk it, since over-cooling of scalar causes many diseases that can lead to the death of pets.
When changing water, it is necessary to monitor the persistence of the temperature level, since constant temperature drops are a serious stress for the scalar: they lose their color from this.
The ideal conditions for an angelfish would be a 25 ° aquarium with a constant temperature without hesitation. If you make the minimum effort, it is quite possible to achieve, and the scalar will be healthy and beautiful!
