Aquarium water temperature

Water temperature for aquarium fish

One of the most important parameters of aquarium water is its temperature. Most aquarium fish feel comfortable at a temperature of 22-26 ° C.

But there are fish that prefer a lower or higher temperature.

For example, discus is a heat-loving fish, a comfortable temperature for their maintenance is 28-31 ° C. But the Goldfish family, on the contrary, prefers cooler water at 18-23 ° C.

Thus, speaking of the temperature regime in an aquarium, one should take into account the comfortable temperature parameters for a specific fish. It should also be noted that the temperature of aquarium water directly affects the lifespan of some species of fish.

For example, neons at a temperature of 18 ° C live 4 years, at 22 ° C – 3 years, 27 ° C – 1.5 years.

Perhaps the most important rule for an aquarist is to prevent sudden changes in temperature (2-4 degrees). Such vibrations are extremely harmful.
for fish.

Today, there are virtually no problems with maintaining the temperature regime in an aquarium. Therefore, when on the Internet you come across articles about the Soviet methods of “boiling with a kettle” involuntarily you are touched.

Only one thing is frustrating – after all, articles on this topic are usually looked for and viewed by novices or young aquarists who are so easily confused with unnecessary, unnecessary information.

The nuances covered in this article for an experienced aquarist will not inspire innovation, but beginners will be noticed.

So, to maintain the required temperature regime of aquarium water, you need to buy two things at the pet shop:

1. Thermostat heater.

2. Thermometer with suction cups.

Regarding the temperature control of the heater for the aquarium – it is chosen based on the volume of the aquarium (its power must be appropriate). They fix it, as a rule, on the back wall of the aquarium, near the filter with aeration, so that it is completely immersed in the input. IMPORTANT: when setting the desired temperature on the scale of the thermostat, the first time (6-12 hours) watch the level of heating of the aquarium water.

This is due to the fact that often the scale of the thermostat does not always correspond to the actual temperature of water heating (especially in Chinese thermostats) or the thermostat does not quite fit the volume of the aquarium. Failure to comply with this rule may lead to the fact that in the morning your aquarium may turn into “a pot with a good, elite ear.”

Well, the second thing to which you should pay attention – the heater for the aquarium should be completely immersed in water. Do not allow it to be in the on state in air (in whole or in part).

This will lead to its rapid overheating.

Regarding thermometers for aquarium – here everything is simple! They are:

glass (ordinary)

in the form of a self-adhesive strip thermometers for the aquarium

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

and electronic thermometers for aquarium $ 12;

When buying a thermometer should pay attention to the quality of suckers. 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 drop it (I have suffered from these gays blue).

I think that with the heating of aquarium water everything is clear: – set, adjusted and forgot.

Let’s now talk about what to do if the temperature goes over the top (from overheating or “summer in August”). Nowadays, this is also not a problem – the 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? Or if you need to urgently lower the temperature?

Ice from the refrigerator will come to the rescue. At one time, I poured water into plastic 2-liter bottles (carefully removing the bottle from the label and glue beforehand) and frozen them in the refrigerator.

After lowering them into the aquarium and thereby lowered the temperature of the water to the desired.

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

REMEMBER: PROVIDING A COMFORTABLE AND CONSTANT TEMPERATURE OF AQUARIUM WATER IS THE KEY TO THE HEALTH OF YOUR AQUARIUM FISH.

Water temperature in a fish tank – Frequently asked questions by aquarists

Have you ever thought about why different fish need different temperatures? And how does the discrepancy affect them?

And how sensitive are they to drops? 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. We collected a few frequent questions about the temperature for aquarium fish and tried to answer them in an accessible form.

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?

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?

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.

Danio pink: content, compatibility, breeding, photo-video review

This article depicts and describes the pink, artificial breed danio rerio! True danios pink looks like this:

Order, family: Carp.

Comfortable water temperature: 21-25 ° C

Ph: ph 6.5–7.5, water hardness: 5-15 °.

Aggressiveness: not aggressive.

Compatibility Danio Pink: compatible with all “peaceful fish”: danios, terence, minor, tetra, scalar, soma, etc.

Useful tips: In my opinion the most beautiful fish of the kind “danok.” Look great flock, on a dark (blue) background of the aquarium film. Fishes quick and gregarious.

They can coexist with many species of fish, even with fish of medium and increased aggression: scalar, goura and even with small cichlids.

In order that the pink color of the fish was juicy, I recommend to buy specialized food (for example, Tetra-color).

Description:

Danio pink lives in the slowly flowing waters of Southeast Asia.

A small fish with a body length of up to 4.5 cm. The body is elongated, flattened laterally. Body of fish beautiful pink, along which alternate white stripes pass.

Fins transparent, colorless.

Fish are kept in the aquarium flock (from 6 copies). Danio pink contain in general aquarium with a length of 60 cm and a volume of 20 liters. The decorations of the aquarium can act – thickets and floating plants, stones, snags.

Fishes also need free space for swimming.

Comfortable water parameters: temperature 21-25 ° С, dh 5-15 °, ph 6.5–7.5, regular weekly water changes (1/5) will have a positive effect on the health of the fish. Need filtering and aeration.

Feeding Danio Aquarium Fish must be correct: balanced, diverse. This fundamental rule is the key to successful keeping of any fish, be it guppies or astronotuses.

Article “How and how much to feed aquarium fish” talks in detail about this, it outlines the basic principles of the diet and feeding regime of fish.

In this article, we note the most important thing – feeding fish should not be monotonous; both dry and live food should be included in the diet. In addition, you need to take into account the gastronomic preferences of a particular fish and, depending on this, include in its diet ration either with the highest protein content or vice versa with vegetable ingredients.

Popular and popular feed for fish, of course, are dry food. For example, hourly and everywhere can be found on the aquarium shelves of food company “Tetra” – the leader of the Russian market, in fact, the range of feeds of this company is striking. In the “gastronomic arsenal” of Tetra are included as individual feeds for a certain type of fish: for goldfish, for cichlids, for loricarids, guppies, labyrinths, arovan, discus, etc.

Also, Tetra has developed specialized foods, for example, for enhancing color, fortified or for feeding fry. Detailed information on all Tetra feeds, you can find on the official website of the company – here.

It should be noted that when buying any dry food, you should pay attention to the date of its production and shelf life, try not to buy food by weight, and also keep the food in a closed state – this will help avoid the development of pathogenic flora in it.

Sword-bearer of aquarium fish: content, compatibility, reproduction, photo-video review

Swordsmen know everything, even those who have never encountered the aquarium world. The Sword bearers gained such fame due to their wide distribution (one can say that they were part of the set of every young aquarist of the former USSR), as well as thanks to a special sign – the tail fin in the form of a sword.

Actually, it was for this tail that the Swordtails got their name.

Homeland Sword – Central America (South Mexico and Guatemala). They live in reservoirs with stagnant and slowly running water, thickly overgrown with various aquatic plants.

Swordtails (Xiphophorus helleri) belong to the family of fish. Xiphophorus helleri is translated from Greek as “xiphos” – the sword, “phoros” – carry.

The prefix “Helleri” was assigned to the sword bearers by the name of the German naturalist Karl Bartholomeus Heller, who first caught these fish in the Mexican lakes and successfully transported to Europe.

In 1848, these fish were first described by Dr. Johann Jacob Heckel – preparator of the Museum of Natural Sciences at the Imperial Natural History Study of the Museum of Natural Sciences in Vienna.

The body of the fish is elongated and compressed from the sides. The swordtail’s mouth is turned up and adapted for taking food from the surface of the water.

Fish can reach a size of 10 cm (without a sword). Females are somewhat larger than males; they are similar in shape to all other petilium.

In addition to the presence of a “sword” on the lower edge of the caudal fin, the male has gonopodia, an anal fin transformed into the sexual organ.
