How many live aquarium fish?

Many novice aquarists, the question arises: how many live aquarium fish. It should be understood that the life expectancy of any living creature depends on its type, proper care, comfortable living environment.

In an aquarium, the life span of a fish is influenced by the degree of its population. If the fish will be many, respectively, and their life expectancy will be reduced. In addition, do not forget that only compatible fish species can live together for a long time. Remember that aquarium fish are cold-blooded: their body temperature is directly dependent on the temperature of the water in which they live. The warmer the water, the faster the life of the fish is due to the accelerated metabolic processes in their bodies.

The life expectancy of fish depends on their size: the life of small fish is short - from 1 year to 5 years, medium-sized fish can live up to 10-12 years, and large fish live 15 years or longer.

A rare change of water in the aquarium, as well as overfeeding leads to a decrease in the life expectancy of the fish. Moreover, overfeeding has a much worse effect on fish than underfeeding. The older they get, the more prone to stress and various diseases.

Life expectancy of some species of aquarium fish

Let's find out how many species of aquarium dwellers live: cockerel and guppy, swordtails and angelfish, telescopes, parrots, danios and others.

Experts disagree on how many years goldfish live. Some believe that these fish live for 3-4 years, others - that their life expectancy reaches 10-15 years. The longest lived goldfish in the UK, which died at the age of 43 years.

Aquarium fish telescope, as well as other goldfish, can live in the aquarium for about 15-17 years.

The zebrafish belongs to the carp and lives from 5 to 7 years.

Scalar, a species of Cichl, can live up to 10 years. In Germany, the long-lived angelfish lived 18 years. The parrot fish also belongs to the cichlor species, which, under appropriate conditions, can also live up to 10 years.

Sword-bearers and guppies are live-bearing carp fish and their life can last no more than 5 years.

Constantly fighting cockerel fish live in captivity for a short time - 3-4 years.

Labyrinth fish gourami can live in the aquarium for 4-5 years, glass catfish - up to 8 years, and piranha, referring to the characteristic haratsinovyh, lives in captivity up to 10 years.

Remember that the lifespan of your aquarium pets depends largely on your careful and caring attitude and proper care.

Which fish will live the longest in the aquarium?

Most people know that dogs live from 8 to 12 years old, cats live about 12-14 years. But how many live aquarium fish? When amateurs dare to get fish in their home, they rarely get interested in the issue of life expectancy, and then they wonder why the pet suddenly died. Although the life expectancy of wild fish is not fully investigated, what to speak about aquarium species. With proper care, many pets live from 2 to 20 years or more, depending on size, personal stamina and feeding. Even a fish with a short life expectancy will live longer than expected, if you create a "paradise" in the aquarium.

Freshwater species

Many freshwater fish species live from 1 to 6 years. The most popular small fish, characterized by a short lifespan: guppies, swordtails, mollies, iris, catfish corridor, some cichlids, rasbora, carnegiella, tiger barbs. There are also several species of fish that live more than 5-6 years with proper care and feeding. Among them: kissing gourami, zebrafish zebra, beta, fish Jack Dempsey.


If you are looking for fish with a lifespan of 10 years or more, then it is better to purchase blue neons, angelfish, Oscars or plecostomus. The famous long-lived aquarium is a goldfish. With proper feeding, clean and healthy aquatic environment, goldfish species live up to 15 years. The oldest aquarium goldfish has lived to 30 years, it is the only officially registered case.

Look at the 25 year old goldfish.

Species living in salt water

How many live aquarium fish who prefer salt water? Despite the narrow distribution in domestic nurseries and the complexity of the content, yet some lovers are trying to provide them with all possible living conditions. A balanced level of salt in the water, proper nutrition and an appropriate volume of the aquarium can prolong life. Most marine fish live in public aquariums, where they live in the best conditions. Many marine fish suffer from diseases at the beginning of life due to poor care.


Some species that live in brackish water live from 2 to 4 years. Among them: butterfly fish, mandarin duck, Moorish idol, bullheads, sea dogs, Napoleon, monodactylus (swallow fish), triggerfish, surgeon fish, degu. Most small tropical seahorses live in aquariums for 3-4 years. Larger seahorses can live longer, but are rarely available for a home aquarium.

More hardy marine species can live in captivity for 10 years or more: they are lion fish, clown fish, eels and sea bass. There are many varieties of angelfish that live long in brackish water. Sea fish angels can live more than 20 years, and grow to impressive size.

Fish families, life expectancy in years of some representatives

Large aquarium fish live longer than small ones, some are able to outlast a person. Since fish are cold-blooded animals, the temperature of the body corresponds to the temperature of the water. As it rises, processes in the body are accelerated, as a result of which the body wears out and ages. It also shortens the life of pets improper feeding or overfeeding. Aquarium cichlids have a sensitive gastrointestinal tract, and in case of an irregular dose or the addition of live larvae, they can easily get sick. Clean water is also important - scaleless species are sensitive to impurities of chlorine, nitrite, nitrate and organic matter. Fishes of the genus Polypterus and Labyrinth need access to atmospheric oxygen.

Representatives of the Haracin family live an average of 5-10 years: tetras, congos, neons, minors, piranhas, metinnis, pacus.

The life span of the Karpovs is from 5 to 30 years: danios, morulius, rasbor, barbs, labo, cardinals (5-10); goldfish, shark balls (10-30).

Cichlids live from 5 to 18 years: discus, frontozy, African and South American cichlids, nichbochromis, astronotus, severum, labidochromis, apistogram.

The representatives of the family Karpazubye, viviparous fishes live for 3-15 years: swordtails, Petsilia, Molly, Guppy and others.

Members of the family of the Viunovye live 10-15 years: the ordinary loach, combat.

Fish species of the Som family live from 5 to 15: glass catfish, otozinclus, plexostomus, pimelodus, synodontis, mystus, banjo, sturizoma, tarakatum.

Other aquarium fish, representatives of different families: apheosimions (1 year); tetraodons, sprinkler fish, clin-belly, iris, leporinus (5); panaki (10).

How many live aquarium fish?

Appearance of som

For almost all types, the specific feature is the specific shape of the head - slightly flattened from above, with a rather wide mouth. Food som is very diverse. Some species specialize in hunting from shelters, others - on eating the remains of meals of large fish and searching for benthic animals, there are also those who eat only algae.

Catfish do not have scales per se. Their body is either completely devoid of it, or the scales in the course of evolution took on the form of rigid plates that protect against predators. This is the scale of aquarium corridor fish. Most types of catfish have whiskers. This is an important tool for finding food and orientation. Many species are able to breathe atmospheric air and have the ability to skin breathing.

Conditions of detention

Somics are usually representatives of relatively small species. Most of them are quite unpretentious in content and easily reproduce in captivity. These fish from those that any experienced breeder will advise a novice aquarist. But when acquiring such a pet, it is worth remembering that catfish are fish that prefer twilight or dark time of the day.

Suitable conditions for keeping these fish in an aquarium are not difficult to create. They are quite suitable temperature from 22 to 27 degrees. But the short-term temperature jumps most species endure quite well. Acidity is neutral, and water hardness is 2 - 12 °.

Look at how a pair of white-spotted agamixis looks for remnants of food at the bottom of the aquarium.

Life expectancy of various catfish

Many novice aquarists are interested in how much their pets will live. Depending on the type of fish and the conditions of keeping the optimum, these aquarium fish can live up to 8 years. However, it should be noted that large catfish in the wild often live up to 100 years or more. Aquarium catfish are very diverse. If you do not take into account the hybrid forms bred by amateurs, then in captivity today there can be about 800 species of these fish.

Kolomuzhny catfish, known under the name loricarium - one of the most unusual representatives of the catfish. Their second name comes from the ancient Roman name for the armor of the legionnaires "Lori ka". The bodies of fish of this family are covered with bony plates, fused together. Their favorite food is algae. Lower mouth, often - sucker. The most popular aquarium fish loricarium: antsistrusy, ottsinklyusy, loricaria, sturisome. Representatives of this family live long enough. For example, Antsistrus may well live in suitable conditions for up to 8 years.

Representatives of armor-clad or calligate are very popular with aquarists. Their body is covered with two rows of bone plates. Hence the name, because this "shell" is a good protection against predators. Catfish of this family are able to breathe atmospheric air. Males are usually slightly smaller than females. How long can these fish live? For example, corridors that are popular among aquarists live an average of 6-7 years. For aquarium fish it is quite a lot. Common representatives of the family are dyanema and tarakatum.

Representatives of the armored family are also frequent inhabitants of aquariums. Bone plates cover their body and head, creating the impression of a cut. These fish have three pairs of rather long antennae. Popular fish: agamixis white-spotted, platydoras striped. A rather large fish Plateidoras, for example, lives in captivity up to 15 years. In nature, it can live for more than 20 years.


Of great interest to aquarists are representatives of the family of fringed - catfish synodontis. How much can they live in an aquarium? From 5 to 15 years. According to some data, individuals in nature live more than 23 years.

See how star synodontists play.

Prized for bright color and catfish flathead or pymelody. The appearance of these fish to a certain extent resembles the African killer whales. These are fairly large fish. Often, only young individuals that have not yet reached their full size are contained in aquariums, for example, the weight-bearing sorubium. The question of how much these fish can live in an aquarium is not easy to answer. From 5 years and more. In nature, their life expectancy is quite high.

These are representatives of not all families of catfish that can be contained in an aquarium. To determine how long a fish will live, it is important to know the length of life in the wild and what conditions it prefers. By creating them you can be sure that the pet will be as comfortable as possible, and his life will be healthy and long.

Breeding

Somiki easily breed even in aquarium conditions. They are all short-term. For successful spawning, it is worthwhile to choose a spawner suitable for the volume and equip it according to the preferences of a particular species of fish. The only common rule for all somobraznyh - increased atmospheric pressure can adversely affect this process. Care of fry, as a rule, is not difficult, and specially created feed for young stock is quite suitable for the first months of fish life.

How many years will the scalar live?

Scalaria is a popular aquarium fish, a representative of the Cichlidae family (Cichlids). The natural habitat is the freshwater bodies of South America (the Amazon and its tributaries). There, the water is saturated with a large amount of dissolved oxygen, which allows it to adapt to different conditions of life. She has a hardy body, body shape and diet allowed to adapt to captivity, transferring some changes in water parameters. Aquarists containing these fish often have the question: "How many scalar live?".

Like a fish belonging to the Tsikhlid family, its lifespan at home can be more than ten years. Under proper conditions of maintenance: proper feeding, clean water, a spacious aquarium, attentive care, the life span of this beautiful pet can be significantly extended. Instances of long-livers among scalar also met.


How much time can live in captivity?

The Amazon River has a slightly acidic pH and a mild level of hardness. Perhaps the most unusual hydrobionts live there, distinguished by their unique appearance and special structure of the organism. In the warm tropical waters of the scalar can live 20-25 years. However, in an aquarium where space is limited and the diet is not so diverse, their lifespan is halved. The built environment, which is completely dependent on the person, does not always provide the fish with a balanced environment.

With proper care, regular cleaning of the reservoir, aeration, scalar live 10 years or more. If she is provided with constant care, without ignoring all the content requirements, she will live an order of magnitude longer, even 20 years. It seems that 10 years is not a long time for joy, I would like more. But this figure is considered to be solid for not very big aquarium fish.

Watch a video on how best to care for scalars.

What to do to extend the life of the fish

The life expectancy of an angelfish in an aquarium can be 15-25 years, if you follow a number of requirements. First, be sure to launch these fish into a spacious tank of at least 100 liters per pair (female and male). Secondly, install the compressor and the aerator, the fish saturated with oxygen will only be delighted. The compressor must be turned on for 20-30 minutes twice a day.

As for the general cleaning in the aquarium, it does not need to be carried out too often. If you remove the remnants of food and rotted plants in time, the water can be changed less often, some people manage to keep the water in crystal purity for more than six months. Otherwise, water replacement should occur at least 3 times a month. Be sure to clean the soil, wash the walls of the tank and the filter from the accumulated dirt, green algae. Watch the water temperature - the new water should correspond to all the parameters of the “old” one.


Do not forget that the angelfish will live more years if the feed in the aquarium is not worse than they are fed in the wild. In the wild, they are omnivorous: they feed on insect larvae and insects, zooplankton, and plants. Therefore, they can be fed all appropriately feed: artificial for cichlids, dry, frozen and live. You can not give bloodworms and tubers, because they do not live in weakly acidic water. You can see how the fish form brownish blisters at the anus - these are the negative effects of feeding the bloodworm and the strawman.

What decorative angelfish eat: micro-worm, artemia, earthworms, snails, koretra, daphnia, cyclop, lettuce and spinach. It is not recommended to give meat to warm-blooded animals that are saturated with fats. Feed pelleted with spirulina can be additional feeding. You need to feed such portions so that the fish ate the food in 2-5 minutes. Overfeeding is also harmful and shortens the life of fish, food debris can oxidize water, spoiling its quality.

Scalar diseases

Because of the violation of metabolic processes, improper conditions of detention, untimely hygiene, fish can get sick, having lived in an aquarium for few years. With poor aeration, the fish have difficulty breathing, hold on to the surface of the water, gasping for air. The eyes become pale, the gills from the inside become covered with necrotic plaques. In this case, you can gradually increase the aeration by adjusting the temperature of the water and the supply of oxygen.

If it seemed to you that the angelfish in the aquarium is sluggish, swims slowly, the anus is inflamed on the body, this is a disturbing signal. Hexamitosis is a parasitic disease of the gastrointestinal tract. Late intervention with the use of drugs can lead to infection of other fish or death. It is possible to treat with erythrocycline baths with trichopol (50 grams and 10 grams, respectively, in proportions to one liter of water).


A scalar can form a fin rot, which is a consequence of infection with a rod-shaped bacterium. This is the result of heavily polluted water if it is rarely changed. On the body of a scalar appear white turbidity, also the eye corneas turn pale. Later the rays of the fins begin to exfoliate and fall off, ulcers form.The consequences of such a disease can be lethal - a fish will live for few years if it is infected from time to time. Treatment of fin rot: take malachite green, hydrochloride and bacillin-5 (in proportions of 0.1 mg, 100 mg, 4000 units per liter of water, respectively). The solution is added to a water tank. Be sure to process the decorations of the aquarium, plant plants bacillin.

Ringworm - a disease of fungal origin, which reduces the number of years of fish life. Late treatment will be fatal. Symptoms: white bloom on the body. Later, the fungus can spread to the internal organs. For treatment it is necessary to use streptotsid, bacillin-5, copper sulfate, potassium permanganate (in the proportions of 1 gram, 4000 units, 0.5 gram, 0.05 gram, respectively). Timely prevention of diseases, quarantine and quality treatment prolong the life of pets.

How long do catfish live in an aquarium?

Somiki are beautiful and unpretentious fish that even beginner aquarists can easily breed. Homeland aquarium catfish - this is South America. In their natural habitat, these fish prefer standing muddy ponds, where they can easily obtain food by digging worms and larvae from the ground. In aquariums, catfish serve as cleaners, eating food residues behind other inhabitants and cleaning the glass walls of the tank with water from muddy deposits.

Unlike other fish, aquarium catfish are completely unpretentious in content: they can eat almost any live food for fish, the hardness and acidity of the water for them is not an important criterion.

Even a sharp decrease in the temperature of the water in the aquarium by a few degrees will not cause any harm to their health. Due to the special structure of the respiratory system, these aquarium fish can live in very dirty and oozy water, where there is no aeration at all.

Almost all the time catfish are at the bottom of the aquarium, where they carefully examine the shallow soil in search of food. From time to time, the fish rise to the surface of the water to swallow an air bubble that is absorbed in the intestines of the fish. The behavior of animals is not affected by the quality, aeration and purity of water.

To the question "How long do catfish live in an aquarium?" no exact answer. It all depends on the conditions of the fish. If the aquarium is clean, well-aerated, with dense thickets of plants, with a water temperature of up to 25 degrees and an acidity of up to 8.2, then catfish in it can live for about 8 years.

The quality of the feed also affects the lifespan of the fish. Live food is the optimal diet for these bottom inhabitants of the aquarium. It is worth knowing that it is impossible to keep catfish in salted or salted water - this will lead to the death of fish.

Thus, catfish are beautiful schooling fishes that get along well with many non-aggressive inhabitants of the aquarium!

How many live aquarium fish !?

Anton Hromuh

First of all, life expectancy depends on the type of fish. There is an exemplary pattern associated with the size of the fish as a species: small fish do not live long, from one to five years; medium-sized fish (5-10 cm) up to 10-12 years; large fish from 15 years and more. So, for example, astronotus, tsikhlazomy, goldfish, piranhas are able to live 25-30 years, often the owners, wanting to redesign the aquarium, change the inhabitants. Very large fish, catfish, sturgeon, carp can survive a person. The life of many toothfish fish (for example, Notobranchus) is limited by the availability of water. These fish live in puddles, and the whole cycle takes place before the reservoir dries up, only caviar tolerates drought. The rainy season begins - the development of caviar begins. The life of such fish is limited to 2-6 months (depending on the species), good conditions of the aquarium do not help them.
The article mentioned that in an aquarium fish can live longer than the statistical natural age. It affects the absence of predators, the spontaneous course of diseases, stable environmental conditions, the constant availability of food (if, of course, all this is so). But much of the above has negative consequences. Each breeder tends to grow as many fry from the litter as possible. Of course, the most unviable die in the early stages of development (roe, larva, fry), but this percentage is not great compared to the natural one. Diseases and predators are known to destroy weakened, defective individuals, removing them from the gene pool of the population. These fish will not pass on their “defective” hereditary information to anyone. In aquaculture, these factors are absent (or almost absent), most of them survive, including those with hidden defects, which can appear later. For example, in an aquarium full order, the fish are young and healthy, but a corpse was found. In his study of parasitic organisms is not detected, most likely, this is a consequence of the absence of the above factors, in nature, such fish would have died much earlier. So, if a causeless corpse was found, it is worthwhile, of course, to alert, carefully examine other inhabitants (this may be the beginning of the disease), check the temperature, etc., but you shouldn’t get very upset; it happened because it had to happen. Corpses should be removed immediately, avoiding being eaten by other fish.
There is also a temperature dependence. Fish belong to animals with variable body temperature (usually they say “cold-blooded”), their temperature is approximately equal to the water temperature. The metabolic rate of fish depends on temperature, the higher it is, the more intense the metabolic processes. And this means that the longevity is shortened, the fish live as if faster. This, though insignificant, but still affects.
Reducing the life of the fish can be improper feeding. Harmful as underfeeding, the fish just do not have enough energy for growth and livelihoods, and overfeeding, but overfeeding is more harmful. As well as any unfavorable conditions of detention reduce the duration of this very content.
By old age, the fish are gaining maximum color saturation, they can still decorate the aquarium for a long time, but remember that they are more susceptible to diseases and sensitive to other adverse effects.

How many on average live guppies

Nina Bulgakova

I have about 40 pcs in the aquarium. Guppy, they actively breed. How many live Guppy I do not know. But if you need these fish, I can easily share, for free. When I didn’t have a water filter, I found dead fish, when I changed the water in the aquarium, now with a filter, I haven’t changed the water for 2 months, there are no dead fish. You can not keep fish on the window, you need in a remote place and a constant light. You can save lamp.

Dimka Beluev

In nature, guppy body length is usually less than 6 cm. Breeders have bred guppies with a body length of about 8 cm. Females and males are very different from each other in size, shape and color.
The females of the guppy are much larger than the males, the length of their body is on average 5.5-6 cm (maximum - 8 cm), the belly is rounded, nondescript colored, usually gray, brownish or olive in color, near the anus - a large dark spot. The fins of the females of the original (wild) form and most of the pedigree representatives are round and transparent. Breed groups, in which females have a brightly colored body, with ornaments on the fins in the form of specks of black, yellow and reddish color are derived. Males, on average, do not exceed 3 cm in length, they have a small, narrow, brightly colored body in the back part with a pattern of spots of various shapes and colors, passing on to the caudal fin.
In nature, several color variations of male guppies are known. In males from the Venezuelan population, body color is dominated by green; in Barbados, the color is red-black; in Trinidadis, golden-green, blue, and purple. Currently, the efforts of breeders have developed a wide variety of forms of male guppies. They vary greatly in size and shape of the caudal fin and coloration. From wild species of guppy, the males of which have a small rounded fin, breeds are derived that have a ribbon-like, fan-shaped, xiphoid, lyre-shaped, looped, styloid and other forms of the tail fin. The size of the tail fin of males of some breeds exceeds the length of the body of the fish itself. The dorsal fin is diverse in shape. It can be round, triangular, rectangular, ribbon-like.
One of the reasons for the great popularity of guppies is the ability of this South American fish to live in a variety of conditions. Guppy - the most unpretentious of aquarium fish. A pair of guppies can be content with an aquarium volume of 1.5–2 liters, a male needs only 0.5 liters of water, and a female about 1 liter. For large breeds of guppies and voile tails, aquariums should be two to three times larger. Usually, there is enough aquarium in their length, in which there is 1 - 1.5 liters of water for each male, and 2-3 liters for a female. The optimal water level for guppies is 35-40 cm. To keep the fish from jumping out of the water, the aquarium is not topped up to the brim, leaving 5-6 cm free, and the aquarium is covered with a cover glass on top. The length of the aquarium for breeding guppy forms must be at least 40 cm.
The temperature of the water at which guppies can live is in very wide limits - from 15 to 36 ° C. However, it should be borne in mind that the growth and development of guppies depends on the temperature. At very high temperatures (over 26 ° C), the development of fish occurs at an accelerated rate, they mature early and become sexually mature and quickly grow old. At the same time their breed qualities usually do not gain full strength and splendor. At low temperatures (less than 20 "C), the fish feel good, but their coloring becomes less intense. The optimum water temperature for guppies is 20-25 ° C. It is desirable to ensure a constant temperature
