How much should the temperature in the aquarium be?

Optimum temperature level for keeping fish in the aquarium

If the fish contained in the aquarium are of the same species, then there will be no problems in their maintenance. it is enough to maintain one constant water temperature. Some aquarists want to diversify the fauna of their aquarium. In this case, you need to pick up fish with one temperature regime. Knowing the following rules may help, especially for beginners:

  • it is necessary to populate the aquarium with fish with one common habitat temperature;
  • for pregnant fish and fry that have appeared, it is worth starting a separate aquarium with an increased water temperature;
  • per day, the temperature changes in the water in the aquarium cannot deviate from the established norm by more than 2-3 degrees;
  • know what the optimal temperature of the water in the aquarium should be: in cold water it is easier to get sick and in water of a higher temperature, the presence of oxygen decreases;
  • to control the temperature regime, the aquarium must be equipped with a thermometer and a heating system (best of all with an alert sensor).

The dependence of aquarium fish on water temperature

Body temperature in fish is not constant. It is very dependent on the environment. The higher the heat, the faster the metabolic rate and the faster the fish grows.

Each type of fish has its own temperature at which they feel most comfortable. Even exceeding the optimal temperature conditions has a significant effect on aquarium fish.

In an aquarium, especially if it is of a small volume, and there are many living organisms themselves, an increase in temperature leads to a decrease in oxygen in the water. Increased life processes in fish lead to an increase in oxygen consumption. All this affects the state of the water: it becomes cloudy, the smell of ammonia appears, and oxygen starvation occurs in living organisms. In this case, even an air aerator does not help.

Under natural conditions, aquarium fish live in tropical reservoirs, where it is always warm. The temperature drops are not as great as in our latitudes and are 2-3 degrees. Therefore, there is a lower and upper temperature limit for fish. To keep the fish comfortable, they are acclimatized in quarantine. In a couple of days at a high water temperature, if it does not differ from their usual environment, or one or two degrees higher, the fish gets used to a new place of residence. If the temperature regime is lower, then acclimatization may take longer, sometimes up to several weeks.

There is no specific temperature value for everyone, because fish are divided into warm water and cold water.

The warm-water type of fish lives in a temperature range of 18 to 20 degrees. But they can also exist at seventeen degrees of water in the aquarium. These fish require a large aquarium, if you have a pair, then they need at least 40 liters, for two pairs, respectively, there should be 80 liters. With all this, planting and supplying the aquarium with oxygen are needed.

The cold water type of fish also needs a good oxygen supply. But on the other hand, they can live at low temperature conditions (14 degrees), and at elevated water temperatures (25 degrees).

In fact, all this is not an unbreakable rule. Each species has its own specific water temperature, from which one should build on in order to know what temperature should be in the aquarium.

Water temperature value for aquarium animals

The temperature of the water in the aquarium is a vital condition for the existence of the inhabitants. The course of all processes of development of fish and plants depends on what the temperature environment is. To determine the temperature regime, there are special aquarium thermometers. They measure not only how much the water has warmed up, but also how many degrees it can differ in the lower and upper layers. There should be no difference in temperature difference.

If there is such a difference, it is necessary to take measures to restore the balance, since the differences can be detrimental to the fish.

What water temperature should be in a home aquarium

Water is not just the source of life. Which fish will live in the aquarium and how long will depend on its properties. Simple in composition, water is actually a very complex chemical element.

An aquarium owner does not need to know all the chemical properties, it is enough to understand some of them. For example, aquarists need such water characteristics as hardness, the presence of gases dissolved in it, temperature, salinity and the degree of concentration of waste products.

Ways to maintain the temperature in the aquarium

As already mentioned, special means are used for a constant temperature value. These products are primarily intended for heating the aquarium. Experienced aquarists know how much room temperature affects an aquarium. The rest should remember the ways to change the temperature balance of water at different times of the year:

  • not everyone knows that an aquarium refrigerator is used to lower the temperature;
  • if the apartment has an air conditioner, then it will maintain the desired mode;
  • some amateurs blow a fan over the water surface;
  • if there is neither one nor the other, then ice can be used for cooling;
  • heating is carried out by a special heater;
  • when there is no desire to spend money on the purchase of equipment, you can use a regular heating pad.

In any case, a person decides for himself what method he will use to heat or cool water in the aquarium. Using professional devices, there is a guarantee of correct temperature control.

Diversity in the world of viviparous fish

Guppies are widely recognized aquarium fish. Both novice aquarists and experienced specialists are engaged in their breeding. In such a case, it is important to know the nuances, for example, to understand what temperature in the aquarium for guppies should be, how many times and how to feed these fish, whether they need an aeration system, and so on. It is worth saying that guppies attract the attention of aquarists for many reasons:

  • These tiny fish are unpretentious in keeping. A beginner can handle them. Many people start them without heaters, because the temperature in a guppy aquarium can be close to room temperature.
  • Being viviparous individuals, they will not build special islets for spawning. They also do not need to be placed in a separate aquarium during spawning.
  • The sheer number of colors in scales and tail fins makes guppies attractive to aquarists.
  • Watch the bustling life of a small flock of guppies in your own aquarium. the ultimate pleasure for a real esthete.
  • Guppies are kind of aquarium cleaners. They are often advised for beginners to start, because in an unsettled and incompletely neglected aquarium, various unwanted inhabitants, such as white glassworms or nematodes, can appear. So, guppies can easily save an inexperienced aquarist from such a misfortune, simply by eating unnecessary animals.

Lighting

Lighting levels play a fundamental role in the aquarium hobby. Experts recommend using lamps with a power not exceeding 60 watts. In this case, daylight hours should last from 10 to 12 hours. Lighting also plays an important role in the proper development of the plants planted in the aquarium. Without it, the green oasis will simply perish. It is worth remembering that the use of even fluorescent lamps can slightly heat up an aquarium with fish.

Chemical indicators of water

I would like to note that not only lighting with the water temperature in an aquarium for guppy fish plays an important role in the health of little handsome men. The chemical composition of the water is also important. The acidity should be neutral and the hardness should be within 10.25 ° dH.

Optimum temperature in the aquarium for guppies, care and

Nature and everything that is her creation attracted and continues to attract man. Perhaps that is why most modern residents of megalopolises plant exotic flowers, aquariums in their homes, equip full-fledged ponds with living inhabitants on the plots of private houses: fish and waterfowl. Those who are not allowed to carry out large-scale projects opt for small home aquariums. Of course, this decision is due to the fact that lately aquarium hobby is incredibly popular. Anyone can purchase for themselves all the essentials for this hobby at affordable prices. And the selection of exotic fish on the market is so great that your eyes run wide. Here are the predatory giants Astronotus, who love cool things. and small guppies, for which the temperature in the aquarium is not so important, but still does. By the way, today’s material will be devoted specifically to these small unpretentious fish and the correct conditions for their maintenance.

Ideal temperature in a guppy aquarium

Experts recommend increasing or decreasing the temperature in a guppy aquarium, if necessary, on a gradual basis. A sharp drop can harm the health of the fish. During spawning, the temperature can be slightly increased, because at first the fry need more sparing conditions for correct and rapid development than adult adults.

Fry Care Facts

Sooner or later, the guppies will give birth. When this happens, the young should be taken care of. It is better to move the fry from adults. For these purposes, a container with a volume of 20 liters may be quite suitable. But there is another acceptable option: to divide the aquarium with a grid with a fine mesh. So the fry will be able to penetrate through its holes, floating away from the mother, who can eat them. The optimum temperature in the aquarium for young guppies does not differ at all from that recommended for adults. Of course, for the first days of life, it is better to stick to a temperature of 27 degrees Celsius, gradually reducing it to 24.

Reverse osmosis and deionization

The settling of water with its subsequent preparation for the aquarium is possible using the method of reverse osmosis and deionization. There are two ways in which the liquid can be purified and settled. Each of these processes helps remove impurities and any particles that may be in the water. Ionization neutralizes the pH while eliminating various ions that might remain in the water. However, the resulting water is clean, but potentially dangerous. it does not retain its biological properties, which is dangerous for fish. No matter how much praise her crystal purity is, she carries a risk, because she changed the pH level, alkalinity and hardness.

Deionized water removes beneficial salts and trace elements that fish and plants need. Such water is obtained as a result of deep purification by the method of reverse osmosis, or ion exchange. During the pressure process, water is passed through a semi-permeable shell from a more concentrated solution to a less concentrated solution. The casing allows the solution to pass through, but does not allow the components dissolved in it.

Sometimes this water is mixed with infused tap water, but you need to be careful.

Watch the video on the reverse osmosis system.

Aquarium water temperature

For all living things, 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 in animals and plants.

How to prepare an aquarium with tap water

The easiest and cheapest way to stock up on water is to draw tap water into a tank. It is available to almost everyone, suitable for any freshwater aquarium. It is not harmful to fish if properly defended. If a high-quality tap water purifier is not installed in your home, the collected liquid cannot be immediately poured into the tank. Chlorine compounds found in water must be vented within a few days. Why do this? To protect fish and plants from poisoning and premature death.

You can take water directly from the tap into glass jars, and leave it for 3-4 days, covered with gauze. All volatile compounds will evaporate and the liquid will become colorless and free of chemical compounds. It is necessary to check the collected water for smell and color. Chlorinated water smells harsh and has a milky white color.

See how to gently pour the settled water into the aquarium.

Aquarium water heater

If the aquarium is deep enough, the water at the bottom is somewhat colder than at the surface. It is believed that the temperature difference should not be more than 2 degrees, and ideally the aquatic environment should be homogeneous.

That is why a so-called rod heater is most often used when heating aqua. This simple device is structurally a hollow glass (or ceramic) rod, inside which a heating element is placed. nichrome wire.

How Temperature Affects Fish Behavior

With the help of suction cups, the aquarium heater is attached vertically to the tank wall. Most models have automatic heating control function.

Such devices are widely represented on the market. Here you can highlight the aquarium heater of the Polish company Aquael or the Chinese product of the XILong brand. Products from these manufacturers are available with or without thermostats (budget option).

What water temperature do scalars like?

Scalaria (lat.Pterophyllun scalare) is one of the most popular aquarium fish of the Cichlid family. Many species of this fish have been removed from South American waters, while others have been bred by breeding one or more forms. The common scalar is perhaps an example of a classic aquarium fish. a disc-shaped body, tall and slightly short, with lush sail-like fins. At first glance, keeping such a pet in an aquarium is not so easy, but this opinion is erroneous. They are peaceful and non-aggressive. They can accommodate different types of the same calm and medium-sized fish: discus, festivus, cancer, gourami.

It so happens that novice aquarists acquire a scalar without learning the main rules for caring for them. They are launched into a new aquarium where the biological balance of the environment has not been stabilized. Unsuitable temperature, high acidity, hard water will quickly destroy the health of the scalar. The presence of nitrates, nitrites, ammonia, non-evaporated chlorine in water also negatively affects the quality of life of pets. The scalars cannot cope with the fluctuations of such substances. This also applies to the water parameters in the spawning aquarium, where you have to follow the rules for keeping producers and their brood.

Watch the video story about the contents of the scalar.

Therefore, it is important for scalars to maintain the temperature regime. As endemic to tropical freshwater bodies, they are accustomed to warm water. Lowering the temperature of the aquatic environment leads to lethargy, illness, and, as a consequence, death. Hypothermia or too high a temperature is just as harmful as an abrupt change of water to a new one. To keep your pet’s full life, it is worth adjusting the temperature of the water in the aquarium constantly.

What is the maximum water temperature for aquarium fish?

Lighting and water temperature in the aquarium
How to properly illuminate an aquarium? When solving this issue, it is imperative to take into account the following points: the illumination of the aquarium with natural light, the power of the lamp, the depth of the aquarium, the need for specific species of fish and plants in one or another lighting intensity (for plants, the spectral composition is also important). lighting duration.

For example, if the aquarium is located near a window, its inhabitants need less artificial lighting (especially in summer). Fish, with the exception of the inhabitants of shaded reservoirs and those that are active at dusk, are not as whimsical to lighting the aquarium as plants. The life of the latter is highly dependent on the quality and quantity of light. In the vast majority of cases, the aquarium should be lit 12.14 hours a day.

What fluorescent lamps can be used to illuminate an aquarium? Aquarists use the following types of lamps: LB, LD, LTP, LHB, LBU, LDC and some others. Typically, lamps with a power of 20 to 40 watts are used. It must be remembered that the light output of fluorescent lamps is 2.5. 3 times higher than incandescent bulbs.

Approximate lighting power standards: 0.4. 0.5 watts per 1 liter of aquarium volume. for fluorescent lamps, 1.2. 1.5 watts per liter. for incandescent lamps. For fish and plants that cannot tolerate bright light, these rates are reduced. It should be remembered that the deeper the aquarium, the more lamp power should be.

What are the best lamps for lighting aquarium plants? When propagating aquarium plants, the best results are obtained with combined lighting: incandescent lamps plus fluorescent lamps such as LD, LDTs ​​(during flowering and fruiting, plants need blue rays, which give lamps with this marking). Power of incandescent lamps for lighting aquarium with plants. 25, 40, 60 watts.

If you are mainly interested in fish, then in the presence of widespread and unpretentious plants, you can use any fluorescent lamps, preferably warm daylight, with the letter B in the marking (LB, LTP, etc.). as well as incandescent lamps, preferably krypton. The latter differ from ordinary lamps in that their bulb is filled with krypton and they burn brighter, giving more orange rays.

In my room the temperature does not rise above 18.20’C. Will fish live at this temperature? The water temperature in an unheated aquarium is equal to or colder than in the room. This is not enough for warm-water fish. Most aquarium fish and plants live at 24.26 ‘and therefore need heating.

The most primitive heater. incandescent lamp placed outside the side wall of the aquarium below the surface of the water and covered with a metal reflector. The lamp should not be more powerful than 40 watts from strong and uneven heating, the glass may crack. This heater is not very convenient as a lot of heat is wasted. In addition, it has to be turned off at night. Plants stretch towards the lamp and bend, and the side window is quickly overgrown with algae.

Most often, heaters are used from nichrome wire wound on a glass tube, which is placed in a test tube with sand (they are produced by our industry). The power of such heaters is from 5 to 100 watts. They should be used in full accordance with the instructions. In particular, make sure that the upper end of the heater protrudes out of the water. if it gets inside the test tube, it will damage the device.

To maintain the water temperature in a 25-liter aquarium no higher than in a room, 0.2 watts is required for each liter of water, in a 50-liter one. 0.13, in a 100 liter. 0.1 watt. To keep the temperature constant, use a heater with a thermostat. The industry produces various thermostats. One of the most common PTA-Z.

maximum! maximum when I turned on the heater and cooked soup from my fish !! Until now, T was about 35-40 in shock. Minors are dead ((

so 32 is the maximum, but the fish are still alive))

Zhen, depending on what kind of fish. In general, in the summer at room temperature, almost all fish live normally. And in winter it is better to put a heater. I do not advise you to detect the maximum temperature empirically, I feel sorry for the fish)))

When treating most aquarium fish (except goldfish), some aquarists raise the temperature to 34 degrees. But for the content, of course, a lower temperature is needed. Discus stand separately. they need a temperature of about 30 degrees. and gold. they need colder water than others.

Reservoir with settled rainwater

Rainwater is also used in a fish tank. Previously, such water was used for food, but nowadays it is not particularly useful (except for the one that falls in ecologically clean regions). It contains impurities of toxic substances and parasites, so sedimentation and powerful filtration are necessary. Rainwater can contain substances that are not washed out of the air. It receives contamination from pipes, gutters, pipelines, roofs and other surfaces from which it flowed out.

For aquarium needs, rainwater is not always suitable. improper treatment of the liquid harms the fish. How long does it take for the rain to settle? After filling water in a clean glass container, install a powerful filter in it, treating the liquid for several hours. After cleaning, leave the water in a cool place for a few days. However, the risk from such water is great. its use is possible only after laboratory tests.

How to maintain the temperature in an aquarium?

The water temperature in the aquarium should be kept constant. Its fluctuations during the day are allowed within 2-4 ° С. Sharper changes can be detrimental to the inhabitants of the aquarium.

Everyone knows that the temperature of the water in the aquarium is the same as the temperature in the room. Therefore, when, for any reason, it becomes excessively hot or cold in the room, certain measures should be taken.

During hot seasons, you need to know how to lower the temperature in your aquarium. There are several ways to do this:

  • using a special refrigerator for an aquarium;
  • installation of an air conditioner in the room, which will maintain a certain temperature;
  • application 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 increase the temperature in the aquarium. The simplest heater option 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, since it will not be possible to maintain the water temperature for a long time.

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

The temperature in the aquarium, what it should be?

Experienced aquarists know that each type of fish has its own temperature requirements, violation of which will lead to overheating or colds, and maybe even death. For more information about what should be the water temperature in the aquarium for some species of fish, read the article.

All living organisms can exist under certain temperature conditions. For each type of animal, the temperature indicator is different. Fish are animals with variable body temperatures. It mainly depends on the temperature in the aquarium and, as a rule, practically coincides with it.

Every aquarist must know what temperature should be in the aquarium, because it significantly affects the sexual cycle of fish. Some fish species begin to spawn at relatively high temperatures. It is in such an environment that fry and caviar quickly ripen. The life cycle and lifespan of fish depend on the temperature of the water in the aquarium. Sometimes a temporary increase in the temperature in the aquarium is used to treat certain diseases, but this is only a short-term measure.

Experienced aquarists know that each type of fish has its own temperature requirements, violation of which will lead to overheating or colds, and maybe even death. It so happens that the temperature in the aquarium deviates sharply from the norm. What to do in this case? What should be the optimal water temperature in the aquarium?

For most types of aquarium fish, an average temperature of 22-26 degrees is suitable. Only a few labyrinth fish and discus fish prefer a little warmer water. 28-31 degrees. Goldfish, on the other hand, require a little cooler water. They will be satisfied with the water temperature in the aquarium 18-23 degrees. Although goldfish can live for a long time at temperatures of 25-27 degrees, sooner or later they will get sick, since swim bladder dysfunction may develop.

On the aquarium forum there is information that significant temperature fluctuations in the aquarium (more than 2-4 degrees) adversely affect the health of pets. If its changes are smooth, then this is permissible, but sharp changes throughout the day or even several hours are extremely undesirable. This happens quite often with small aquariums (less than 60-50 liters), since a small volume of water cools quickly and heats up quickly. If you open the window for a long time in the cold season, and there is no heater in the aquarium, then the water will cool down significantly in a few hours. Oddly enough, but the fish can also catch a cold, after which they have the opportunity to pick up chilodonellosis or some kind of bacterial infection. If there is no thermometer in the aquarium, then the owner will not even notice the temperature fluctuations.

It should be noted that it is important to control not only the water temperature in the aquarium, but also the air temperature above it. This is especially important when keeping labyrinth fish, which regularly capture air from the surface of the water. For example, lalius and Siamese fighting fish (cockerels), when they swallow air 5 degrees cooler than water, can not only get sick, but die. That is, when keeping these types of fish, you should be especially careful with airing the room in cold weather.

Aquarium Temperature Tip!

Overheating is also dangerous for fish. As you know, warm water contains much less oxygen, which is especially needed by well-fed fish. Overheating of the aquarium can occur as a result of prolonged exposure to sunlight, from the heat of a radiator or lamps. It should be noted that you can reduce the temperature in the aquarium of the upper layers of water by 1-3 degrees using a cooler.

Aquarium water temperature

For all living things, 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 in animals and plants.

Optimum aquarium temperature

There are no definite numbers that will satisfy every aquarium, as the temperature depends on factors such as its inhabitants, plants and the chosen maintenance regime. The temperature range for most fish is 20 to 30 ° C, however, the optimum temperature should be maintained for each individual type of fish.

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

For catfish, the optimum temperature in the aquarium is in the range from 18 to 28 ° C. However, catfish is an unpretentious fish, therefore it can easily withstand significant deviations from these limits, but for a short time.

The temperature in a scalar aquarium is, in principle, a wide range. The optimum is 22-26 ° C, but they can easily tolerate a drop in temperature and up to 18 ° C, but they need to be lowered gradually, without sudden changes.

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

The recommended temperature for a cichlid tank should be between 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 lethal. At the same time, a significant decrease in temperature even to 14 ° C can be tolerated by the fish quite calmly (of course, not for a very long time).

Water temperature for aquarium fish

Water temperature for aquarium fish

One of the most important parameters of aquarium water is its temperature.
For most aquarium fish, the optimal water temperature is 25 degrees. The fact is that for tropical regions, frequent changes in water and air parameters are uncommon. For example, the temperature range of air in Southeast Asia throughout the year fluctuates between 26-29 degrees Celsius. In South America, it is also always hot and humid, year-round air temperatures are in the range of 25-28 degrees.

That is why the temperature of the aquarium water must always be stable and for most fish it should be 25 ° C. But there are fish that prefer a lower or higher temperature.

For example, discus. these are thermophilic Amazonian fish, the comfortable temperature for which is 28-32 ° С. But the family of Goldfish, on the contrary, prefers cooler water 18-22 ° С.

Thus, when talking about the temperature regime in the aquarium, one should take into account the comfortable temperature parameters for a particular fish. It should also be noted that the temperature of the aquarium water directly affects the lifespan of the fish. For example, neons live 4 years at 18 ° C, 3 years at 22 ° C, and 1.5 years at 27 ° C. That is, with an increase in temperature, the life cycle is accelerated.

There is one more aspect. the effect of temperature directly on the aquarium itself as a whole. The fact is that temperature, as well as other water parameters, affect the biological processes of the aquarium. For example, the higher the temperature, the less oxygen will be contained in the aquarium water. And this can lead not only to oxygen starvation of aquatic organisms, but also to disruption of oxidation processes. It’s no secret that O2 is an excellent oxidizing agent. And if it is not enough, then the processes of oxidation of fish waste products will be hampered. The negative consequences are obvious: an unpleasant odor from the aquarium, dirty, muddy water, high concentrations of nitrogenous compounds. This is why you must always be sure that the temperature in the aquarium is stable.

Today, there are virtually no problems with maintaining the temperature in the aquarium.

Regarding the thermostat of the aquarium heater. it is chosen based on the volume of the aquarium (its power must be appropriate). It is usually attached to the back wall of the aquarium, near the aerated filter, so that it is completely submerged in the inlet. IMPORTANT: when setting the desired temperature on the thermostat scale, for the first time (6-12 hours), monitor the level of heating of the aquarium water. This is due to the fact that sometimes the scale of the thermostat does not always correspond to the real temperature of heating the water (especially in Chinese thermostats) or the thermostat does not quite fit the volume of the aquarium.

Well, the second thing you should pay attention to is that the aquarium heater must be completely submerged in water. Do not allow it to be in the switched on state in the air (in whole or in part). This will lead to its rapid overheating.

On a note, there are also flow-through heaters that are connected to an external filter.

About aquarium thermometers

Self-adhesive strip

(I do not recommend it. Creatively. yes, practical. no, especially since this strip “fades” over time);

Electronic thermometers for aquarium 12;

When buying a thermometer, you should pay attention to the quality of the suction cups. If they are weak, the thermometer will often fall to the ground. In addition, there are fish that pathologically may not like the thermometer and they will deliberately dump it.

Let’s now talk about what to do if the temperature goes off scale (from overheating or “summer in August”). Nowadays this is not a problem either. an air conditioner will not only cool the room, but also lower the temperature of the water in the aquarium.

Another question is what to do if it is not there? Or if you need to urgently lower the temperature? Ice from the refrigerator will come to the rescue. At one time, I filled 2-liter plastic bottles with water (after thoroughly cleaning the bottle from the label and glue) and frozen them in the refrigerator. Then he lowered them into the aquarium and thereby lowered the water temperature to the desired.

This method of lowering the temperature has two drawbacks: firstly, frozen bottles and ice heat up quickly enough. they often need to be frozen, and secondly: sharp, frequent temperature changes are poorly tolerated by aquarium fish. If the temperature is “tolerable” it is better not to add the ice bottle.

The best option for cooling aquarium water is still a cooler. see more here.

Pterygoplichts

These large catfish are native to the tropics. Therefore, it is optimal for catfish at a temperature of 25-28 °, you can briefly lower it to 22 °.

[attention type = green] Catfish can withstand an increase of up to 30 ° C with ease.

Synodontis

An unpretentious catfish family that lives well at room temperature. Optimum 21-25 °, minimum 19, maximum 29.

For swordsmen

Under natural conditions, swordsmen live in the waters of Central America, where the average water temperature ranges from 22-25 °. The sword-bearer can spend some time in cool water with temperatures up to 15 °. The upper threshold for the life of swordsmen is 29 °.

For scalars

In nature, they are found only in warm tropical waters. Optimum indicators for the life of scalar should be within 24-27 °. Lower limit 19 °, upper limit 33.

In warm water, scalar immunity rises, they grow faster and begin to multiply. However, an excessively warm environment reduces the lifespan of the scalar.

Agamixis

These peaceful small catfish also need warm water. The optimum temperature for catfish is 26-27, minimum 23, maximum 32 °.

Why the right water temperature is so important?

Fish are cold-blooded creatures, which means that their body temperature always depends on the ambient temperature. With an optimal indicator, the fish feel good, do not get sick and do not suffer from metabolic disorders.

If the water is too cold, all processes in the body slow down, immunity decreases sharply, the fish become inactive and susceptible to any infections. With strong water heating, metabolic processes accelerate, fish become very restless, begin to consume a lot of oxygen and experience a lack of it. In this case, they float to the surface, convulsively swallowing ordinary air. Death often occurs precisely because of oxygen deficiency.

Sharp shifts in one direction or another affect the health of aquarium inhabitants even more.

[attention type = red] Already at a drop of 3-4 °, the fish develops a shock state, which very often leads to death. [/ attention]

For aquatic turtles

Typically, tropical species enter aquariums, currently the most popular is the red-eared turtles. This is a thermophilic person who does not tolerate cool water. The optimum temperature for red-eared turtles ranges from 24 to 29 °. Derating for a short time is only possible up to 21 °. The maximum possible temperature for red-eared turtles is 34 °.

For African cichlids

In nature, they live in warm rivers, where the water can cool down to 20 ° or warm up to 30. The optimum temperature for African cichlids is 22-24 °.
