Ordinary or redobheha piranha (Pygocentrus Nattereri) - the sadly famous inhabitant of freshwater South American mainland and perhaps the most famous representative of the genus.
The area of \u200b\u200bpropagation of the species includes water bodies located between the Orinoco river basin, in Venezuela, in the north and the Parran River, in Argentina, in the south.
Piranha - High-flue silver fish with a greenish blue back, a brown-orange throat and belly, at first glance it seems fairly harmless if it were not for a large head with a powerful alternating jaw in the jaw with a sharp as a razor, strong triangular teeth issuing a formidable predator.
Sharp as a razor triangular teeth - issue a terrible predator in Piranv
In the upper jaw, the teeth are slightly smaller than in the bottom. Moreover, in the usual condition, the teeth are covered with massive lips so that only their most tips are visible. Special location of the teeth and the movable lower jaw allow piranham. To tear up quite large pieces of flesh from your victim.
Predatory lifestyle pirates It was reflected in the size of the eye and the nostrils. W. pirates Very acute smell, they are able to find a potential victim even in complete darkness among thick vegetation.
In young individuals on a silver body, black spots are scattered. Gybel covers, chest and anal fins, including the belly itself - bright red. The tail is cut off with a wide black cat.
With age, black spots disappear, and the body acquires the color of old silver with small golden glitter small scraps. But the red shade on the belly and fins is saved. The fat fin is completely deprived of the rays, while the dorsal fin contains from 14 to 18 branched rays.
Its stretching from abdominal fins to anal keel, covered with biased sawtooth scales, because of this particular, in America, Piranhe is called fish-saw.
Thanks to numerous myths telling about their bloodthity, Piranha Pretty rarely contained in amateur aquariums, although care for these fish does not represent any difficulties.
Adults piranha - Pretty large fish, even in aquarium growing up to 20-25 cm.
In nature piranha It is kept by large flocks, so for the content in the aquarium it is better to immediately acquire at least 8-10 fish.
For a group consisting of ten pirates about 4 cm in size, at first there are enough aquarium with a volume of 100-150 liters, but it is better to immediately allocate them a more spacious tank, as for several adults pirates Aquarium and 500 liters will not seem too spacious.
Flock of adult piran in aquarium
To decorate aquarium with piranhami You can use various decor elements: stones, squals, lively or artificial plants.
But the best solution is densely planted with alive plants a reservoir with open sections for swimming, with muffled lighting corresponding to the needs of plants.
In such conditions, fish feel more confidently, they begin to move more actively, demonstrating natural behavior.
Adult Piranhas in Aquarium
Piranha - Predators, therefore, water vegetation, as food, they are not interested.
Piranham.But, however, as many other fish are peculiar to cannibalism, and he is inherent in not only adult individuals, but also a slightly grown fel. Therefore, it is better to acquire young belonging to one litter, thereby significantly reducing the risk, to be eaten by some of them in the near future.
The cause of cannibalism usually lies in the flange or disadvantage of feed. With a dense landing of fry, injury in the form of bites are inevitable, while some of the injured fish die, and the part, thanks to the high immunity survive. Moreover, the wounds are healing quite quickly, already after a few days they resemble only small recesses in the bite places.
Aggression causes the wrong, from the point of view of the pack, the behavior of the victim. This may be a patient or injured fish, and the representative is not important, this is another type or one of the members of its own flock.
Despite the reputation of bloodthirsty predators, in captivity, Piranha It is strongly susceptible to stress and sometimes there are very bugles. With the slightest danger, the pack is fully hidden in the thick of plants.
Falls just lie on the side, pretending to be dead.
Therefore, to be afraid that you will remain without your finger at one fine, when performing periodic work in the aquarium, it is not worth it. Piranha Always stay away from the same scraper or siphon.
But also forget about who we are dealing with, also not worth it, drove into the angle, when catching, a large part is quite capable of injury. But since most aquarists catches the fish with a porch, and not with their hands, they suffer from pirani in the first suture.
If the fish are full, then the first reaction, from the subject to the aquarium will be rapid escape.
If pirates Do not feed for a month and, by the end of such an experiment, do not eate each other, then any biological object that fell into the water can cause an attack.
Pirate diet
In nature piranha Basically feed on fish, which they are actively pursued, or attacking an ambush. In addition to fish, their diet includes insects, crustaceans, birds that are in water, as well as mammals, reptiles and amphibians. Speaking otherwise, prey pirates Any living organism can become in one way or another the attention of the hungry flock of predators and did not have time to leave water during. Some steits piratesat certain times of the year, concentrated under the trees on which birds nest. Patiently waiting the moment of chick dropping out of the nest.
Feeding pirates The aquarium does not cause any difficulty. Their casual diet can consist of fillets of almost any low-fat fish, pieces of squid, shrimp, beef heart, etc.). They will not be refused and alive aquarium fish. Thanks to a wide throat and mobile lower jaw, adult piranha Without much effort, it can wholely swallow ten centimeter fish.
Young felting every day, adult fish - every other day or also daily, but to prevent obesity, they arrange one or two unloading days a week.
Giving large pieces of food, you should hang them on the wire. When lowering such a piece in the aquarium, at the first moment the whole flock rushes into the loose. After a while, as a rule, the smallest individual is decided to swim to meals and bite a small piece from it. After all the other members of the flocks are convinced that with their relatives, nothing terrible happened, they quickly rush to prey and in a matter of seconds nothing remains.
Often in publications mentioning about piranyah, It is said about their abilities to snack almost steel wire. In fact, in the process of nutrition, piranha behave very carefully. Feeling any solid matter under the teeth, piranha It tries to bite the piece smaller, if it does not manage it completely refuses to attempt to bite anything.
His victim piranha Cut off with your sharp as a razor with teeth, all soft parts, a skeleton, as a rule, remains intact. Although in the excitement, even a large fish, thrown on food, it can easily be overlated in half.
PiranhaAs in other matters and other predators are eating quickly and inaccurately, trying to fill their stomach opportunities if possible. Small pieces of feed fallen on the bottom are usually ignored. Therefore, it is recommended to give fish to stern chunks that they can swallow completely without breaking.
To maintain the red color in the painting of piras, it is desirable that shrimps or pinkish meat are turned on in their diet.
Piranha - sexual dimorphism
Sexual dimorphism is expressed weakly: females are usually larger than males, but in order to judge this, fish should be of one age and be grown in the same conditions, which in practice is unlikely.
A more faithful sign is a keel abdomen, in the male, when looking at it in front, it has the shape of the letter V, and in females - the letter U.
Reproduction of pirands in the aquarium
Hawk piranha It turns out of size about 15 cm, usually this occurs at the age of one and a half years.
Piranham.Grounding in aquarium for reproduction is not required to create any special conditions. At least it is necessary for this, it is clean and warm water, sufficient volume, plus a variety of meals.
Spa is not depends on the time of year. After the first orcrometics, the following usually occur with periodicity one or twice a month. Reproductive ability u pirates Saved for quite a long time.
You can judge the upcoming spawning on the changed color of fish and some changes in the setting in the aquarium. In the spawning period piranha Darken, acquiring almost black color.
Snerest occurs in an open place. First, the male is building a nest, which is a hole with a diameter of about 20 cm. All the growing plants nearby are mercilessly dug under the root.
Icroids usually occur in the early morning. The female lays around one and a half thousand bright orange eggs having a diameter of about 2 mm. On this, its role ends. The rest of the care of Iquara takes on the male. He is selflessly throws his hand on the shelter glass. Any other items appearing within the nest boundaries are attacked.
The caviar of the male covers the soil. Periodically, it makes sharp circular movements around the nest and foaming the masonry by fin, creating the necessary current of water. For normal otloeva larvae, in spawning it is recommended to use a rather large soil, since the petty quickly flies, and the care of the male only aggravates this process. As a result, a part of the caviar is choking, and the larvae turned off simply lacks forces in order to get out.
The activity of the male, care for the nest, falls every day. And flooded larvae become fully granted by themselves.
Depending on the water temperature, the larvae appear on 2-4 days, and freely float only a week later.
The launch feed for them is the Naupliusi Artemia, but after a few days the fry can eat a cut tube, and a week later trying to collect worms entirely.
With abundant feeding, the fry grow very quickly. Having achieved monthly age, young already looks like small shiny coins with a dark spot at the base of the tail fin.
A month later, black spots appear on the body. At the age of three months, the fodder begins to perform ahead of the lower jaw and finish finish. Now they are already becoming similar to adults. pirates.
Young Piranha Ordinary Piranha
At this age, the felts can be added to food with robust fish and meat, as well as chopped shrimps. When moving to this feed, more attention should be paid to the quality of water in the resulting aquarium.
If the spawning occurred in the species aquarium, then the larvae and the fir times can be grown in it. Adults piranhaThe larvae do not pay any attention.
The danger of being eaten comes when the size of size 5-6 cm is achieved. In a separate inquarium, such problems may occur when it reaches half-capacity fish.

Piranha is a dangerous exotic fish that can be decorated with any aquarium. At the same time, it will be delighted with his own species and even some thrill of your friends and guests. But before starting this fish in the home aquarium, it should be carefully examined by its features.
Habitat in nature
Piranhas live in fresh reservoirs of South America. It is found in Amazon's pools, Orinoco, Essekibo, in Parana and Uruguay. Almost in all countries of the South American continent are known.
Did you know? If the South American shepherd needs to translate cattle across the river in which Piranhas are found, the only chance to do is to give« tribute» . One cow gives the owners of rivers. While predators tear the prey, the shepherds translate the rest of the herd.
Description
Family of Piranyev belongs to the leopard fishes of the Characin-shaped squad. Some species reach more than 1 m in length. Young individuals have a silver color, with black spots on the sides. Feds - red or yellow shade. Adult fish painted in silver-green with a reddish tint (maybe purple) tone. The tail fins bordered black.
Thanks to the special structure of the jaws, the fish can pull out pieces of flesh from his victim. Triangular teeth reaches 0.5 cm long and are located in such a way that, with closed jaws, the top falls exactly in the slots between the lower. Jaws are capable of working as in a vertical plane, cutting off pieces of meat, like guillotine, and in horizontal, pulling down denser and large pieces of production.
In the natural medium, Piranhas are a kind of sanitary panels. They eat the flesh of the drowned or dead animals to the bones (after the Amazon spills there are a huge amount). If not river predators, this flesh would quickly rotted at high temperature and humidity, becoming a source of infections.

Aquarium and scenery parameters
If you decide to make an exotic predator at home, you need to comply with some requirements for the aquarium arrangement. Piranhas in captivity love to be in niches and shelters, with the equipment of the aquarium it is worth taking care of it.
Did you know? The officially registered long-lived among pirands is a red paka, who has lived 28 years.
The volume of the aquarium should be calculated by such a rule:3 cm of the length of the body of fish - 10 liters of water, but at the same time the aquarium must contain at least 150 liters. Fish and so rather, in its dimensions, and the insufficient volume of housing adversely affects its character. Fish can live both, but it feels better in the company of themselves like.
These predators are voracious, leave behind a large number of life products. Accordingly, you should take care of a good powerful filter, you can use several.
Vegetation
Piranhas though are predators, but with pleasure eating various aquatic vegetation. So all your efforts on habitat landscaping can go to satisfy its gastronomic needs. Although no greens leave the aquarium too. The best solution will abundantly fill the aquarium with artificial plants. Especially willingly fish eat greens during spawning.
Priming
Sometimes piras prefer to keep inquariums without soil, it is more convenient to care for them. If you like the traditional decor more, it is quite suitable for the most ordinary sand or gravel.
Water
Water in the aquarium should be well aerated and comply with the following requirements:
- temperature - 24 ... 26 ° C;
- acidness - 6.0-7.0;
- hardness - 12-16 DH.
Lighting
The principal value does not have the lighting, although it is believed that preference should be given to the white light. Lighting rate - 0.5-0.7 W / l.
Feeding
In the wild, Piranha eat literally everything. Therefore, in captivity, their diet is quite extensive. You can feed predators with other fish, mollusks, invertebrates, amphibians, worms and fruits. The most popular diet for aquarium species:
- a fish;
- krill;
- cuttlefish;
- squid;
- worms;
- meat offal;
- crawls;
- small rodents.
Important!Mammalian meat, although it is permissible, but is not good food for Piranha - the fish is badly digested, and this can lead to obesity.
Meat or fish (do not recommend river) Cut in fine or twisted on mince. Machine stirred with vegetables, and feed predators with such a puree. It is impossible to use only beef for feeding, it may cause an endocrine system disorder (black of color).
You can feed fish in this way: to tie food to thread (fish, meat), and omit into the aquarium by 2.5-3 minutes, after the expiration of the specified time, get a thread and what remains on it.
The rate of nutrition for a predator is an approximate weight of his body. From time to time it is worth to arrange very nightlife, to avoid obesity.
Compatibility with other inhabitants
Subject to full feeding and sufficient volume of the Piranha aquarium, it is quite normal with and.
Character and behavior
Even in a flock of fellow, there are often clashes and cases of cannibalism. After watching the pack, you can find the leader in it. Often it is larger than the rest of the fish, the first eats and all his behavior shows that he is a leader.
Representatives of one species in groups of 8-10 individuals are best. In some external influences, the fish can start panicing:
- strong knock on the wall of the aquarium;
- bright flash of light;
- a strong splash of water;
- finding into the water of a foreign object of large size.
Did you know? Piranhas make a similarity of sounds. If you get fish out of the water, she publishes sounds similar to the dog Lai, when the fish share food, their exclamations become like the battle of the drum. If one fish breaks off the user's private space, Piranha begins to "caric".
Reproduction and sexual differences
Piranhas become capable of reproduction aged 16-18 months. The male distinguish from the female is quite difficult. It is best to watch the fish - before spawning, the males becomes brighter, and the characteristic sign of females is rounded by the abdomen.
The next step will be the choice of a secluded room for creating a spawning. To keep together those fish that live enough and well compatible. Sneshilla should be spacious, have a large volume, and water is clean, with an indicator of a rigidity of 6.0-7.5 and a temperature of 26 ... 29 ° C.
First, the couple will find a place for spawning. The fact that the place is chosen will be evidenced by the aggressive behavior of the fish. This is their normal reaction - thus predators show that the territory is occupied. Then you can see the darkening of the color, and the formation of a small deepening at the bottom. After throwing the caviar and fertilization of the male to fiercely protect fertilized eggs.
Icra is usually bright orange, after 2 days begins to cross. Then, after 2 days, Malek appears, it is necessary to take it gently with a sidet.
Important! Be careful - during the birth of the offspring of the male can attack everything that is moving.
Malks should immediately contain in the usual conditions for this type. They have excellent appetite from the smallest age. It is best for feeding the fry to use Artemia, Daphny and Moth. Finger the fools need twice a day. After 4 weeks, they will reach approximately 1 cm long. In a two-month-old age, the fins in the freshers acquire an orange shade.
In the conditions of crowding, the fry becomes aggressive. To eliminate cases of cannibalism, sorting every week should be sorted. It is necessary to leave about the same in size of the fry, sifting smaller.
- up to 1 month - 300-500 pcs.;
- up to 2 months - 200 pcs.;
- up to 3 months - 100 pcs.
Health
Piranhas live in captivity 10 years and more, in the content they are unpretentious. The health indicator of predators is their appetite. If the fish do not fight for food, when feeding does not show a supelness and some anger, it means that something is not in order with the conditions of detention. Piranhas are quite sensitive to temperature, water acidity and saturation with its oxygen. If the inhabitants of the aquarium have a bad appetite, pay attention to these indicators.
Individual characteristics
It is worth noting that rumors about the bloodthirstiness of pirands are greatly exaggerated. Almost half of the species are herbivores (about 40 out of 80), and only 4 varieties, the so-called "True Piranhas" generally represent a threat to mammals and a person.
Predators are distinguished by fast tissue regeneration. Injured leather and fins quickly restore their functions. Cases were recorded when the fish felt firmly, remaining without her eyes after the skirmish with the opponent.
In captivity, Piranhas are less aggressive than in a natural environment. Sometimes they even have a buggy, clogged into the gaps, holes and most of the time spend there. Activity is shown only when feeding. In general, feeding deserves special attention.
If the piranhas are normally feed on, they are completely peaceful with representatives of other species, but if the power is bad, or in the aquarium is not enough space, the fish can fight even with representatives of its kind. And the fights are cruel, predators often burst pieces of flesh and cause injury.
Stress among fish can cause moving to another aquarium, it happened that during this procedure, the piranhas threw a saccha mesh.
The smell of blood is able to cause rabies from a predator. There are cases when Piranhas came into fury when the water was added to the aquarium in which the meat washed.
Important! Piranhas eat their wounded, weak or sick female.
Precautions
You should not put an aquarium at a low surface, especially if you have a little baby or a pet. It is not necessary to carry out work in the aquarium bare hand if it has the slightest wounds. In other cases, working with a naked hand (for example, remove the residues of food), it is quite acceptable, just try not to drive the fish into the angle.
Piranhas are bright and notable inhabitants of aquariums, it is difficult for them to not pay attention. But contrary to reputation earned due to Hollywood films, the life of fish in the aquarium depends, above all, from man. Try to remember that, despite all the aggressiveness and strength, it is, first of all, aquarium fish requiring a corresponding relationship.
Among the fish, the horror of a person, the most terrible is the White Shark. But no less candy stories tell about the little fish-piran. In many legends, she is able to unbridling a large animal in just half an hour. Only a drop of blood falls into the water, turns into a distraught demon who throws on everything that he comes across.
Fish Piranha - Beach South America
Here it is - the famous and legendary. Little fish, just some 20 cm, with violet (in females) or blue-black (in males) by color. May be also olive-silver or bright red. Cute fish? Believe me, it's better not to deal with it. Piranhas are known for the reputation of bloodthirsty fish. It is enough to look at its highly developed jaw with a lot of sharp, pyramidal teeth. 
Already the name itself is a threat. The word "Piranha" is borrowed from the South American Indians and means "toothy demon". Indeed, they have scary teeth. The muscles of the jaw are so developed that Piranha can "cut" the smallest piece. She does not tear up production, but cuts it in parts like a scalpel surgeon. The teeth are very sharp, no thick skin is protected. Adult Piranha is able to eat a stick or human finger. Piranha can contact even steel. They are especially dangerous during spawning, when a couple of fish initially, and in the future one male, guard the masonry of caviar.
Fish Piranha: predator or not
The Piranian family includes several types of predatory, as well as a large number of herbivorous species. The most common is an ordinary or, as it is also called, red Piranha. It is common in fresh water bodies of South America, there are almost everywhere in the Amazon pools, Orinoco and La fees. It can also be found in the eastern foothills of the Andes and Colombia, around the Amazon basin, in Bolivia, Paraguay, Peru, Uruguay and Northeast Argentina. Multiple piral populations are also available in the United States and Mexico, in Europe, in Spain and other countries where they came from amateur aquariums.
Activities are characterized by young people, which is more often going to the packs. They are constantly growing in search of food. Adults are distinguished by solid behavior: they are the bulk of the time in the place in their favorite, sometimes hiding behind the cores or in algae, that is, they prefer not to chase prey, but to wait for her from shelter.
Although - Predator and has a reputation for "submarine wolves", these fish are very bugles and easily fall into shock during fright. With a sharp movement, the fish is pale and falls sideways to the bottom, after a while the fish will find, starts to swim as usual, and then beware, Piranha will defend and attack.
How the Piranha fish hunts
With huge flocks, they attack any prey, pulling out pieces of meat from the body of the victim, they are capable of cleaning a large animal in a minute. These fish attract water bursts and blood smell. Nursing predators - an unpleasant sight. Water literally boils from the fish driving there. And the victim surrounded by these predates literally disappears in his eyes.
Piranhas also show themselves as cannibals: can eat another piranha, caught on the hook. Young Piranhas can grab a piece of fin at their neighbor during feeding. That is why it is very difficult to meet not crumpled fish - almost all of them in wounds and scars.
It is not known a single case when Piranha would have a man. However, every year about 80 people suffers from this predator. Wounds that remain after her teeth are very serious and never stand up to the end. The best, if, after meeting with Piranhas, only the scar will remain. A lot of cases when, because of these cute fish, a man lost some of his parts of the body - a finger, and then the whole hand or leg.
In the media, there are reports of the presence of a legendary South American river predator for several years. Is there a reason to beat the alarm?
What is Piranha, everyone knows without exception. This is a river fish that lives mostly in the warm fresh waters of South America. Fish refers to predatory species, but there is a herbivore piranha.
From all over Russia, Russia is reported on the appearance of pirands in rivers, lakes and reservoirs. A few cases of attacks on people are known. The most interesting thing is that the official authorities recognize the fact that "some individuals" can be in Russian water bodies, but declare the full impossibility of their reproduction and rolling.
Piranha has extraordinary adaptability. There are cases when the herbal subspecies of this fish passed to a predatory lifestyle and vice versa. Officials declare that the reproduction of this type in Russia is impossible due to the cold climate (on off. These fish will spawn at water temperature from 28 o C).
However, scientists insist on the fact that the main factor for reproduction is the presence of a feed base. And since in the domestic reservoirs of the natural enemy, Piranha simply cannot be, it has every chance to turn into an invasive look.
How does this fish get into our reservoirs? It is difficult to build assumptions here. The most believable version is "released" from the aquariums fish. Once into the river, the individuals quickly adapt and begin to multiply. Since the increase in population is developing in geometric progression, the most interesting events are waiting for us ahead. Russian fishermen have every chance in a short time to enjoy this, quite tasty fish.
Fish Piranha inspires horror not only in native South America, but also residents of all other continents. In terms of the number of myths with a small river inhabitant, only a huge shark can be compared.
She is the only one who can compete with it in the bloodthirsty and sharpness of the teeth. And although Piranha is significantly inferior to sharks in size, it does not interfere with it unhindered to hosting in South American rivers and lakes from Venezuela in the north to Argentina in the south.
Biological diversity
In total, the ichthyologists are 9 genera, consisting of 58 piral species. Only 25 species are predators, and the rest are herbivores. However, in the opinion of scientists, several thousand unknown species of haracin fish can live in the waters of South America (including Piranheyeva) in the waters of South America.
The largest types of piran
The largest types of piras reach the length of the half-meter at a weight of 2.5 kg, and the smallest - only 25 cm with a weight of 0.5 kg, but, despite the size and color, all piranhas have the teeth of amazing sharpness. SerraSalminae (Latin name "Zubastikov") belongs to the detachment of carpets, the family of haracin, the subfamily of the piloskin.

Pirates teeth
Contrary to the classification, the teeth of the pirands are reminded not to the saw, but rather a razor or sharply ended scissors. They have a triangular shape (the upper triangle is included in the groove between the lower) and reaches 4-5 mm in length. These teeth are not just a "sharp, like a razor" metaphor: In the old days, the Indians really used them as a razor.
But some sharp teeth, Piranha is not limited. She has surprisingly powerful jaws. First, the jaws are closed and the teeth are cut off what is in the mouth, from all the rest. The closed jaws move in the horizontal direction (that is, Piranhah seems to be chewing), and her teeth, like knives of the electric shaver, snack solid materials, so before the jaw can not resist no residents with bones, nor even thick sticks!
Gastronomic delicacy
Residents of South America are catching and happy to eat piras, whose meat looks like a trout, although it's not so easy to catch it. For catching Piranhas, huge hooks are used, which are used for catching huge fish, weighing dozens and hundreds of kilograms (and Piranhas weigh only 0.5-2.5 kg) and a thick fishing line. However, even having breaking down from the hook, Piranha will again and again approach the bait, until it fell into dinner.

The origin of the name - Piranha
Piranha received his name fish from the word "Pirusiny". So it was called those who lived on the territory of Brazil the Indians of the Top Top. "Fir" means "fish", and "blue" - "teeth", that is, "Pirusigna" is a "toothy fish". The Portuguese arrived in Brazilly redested the name to the more familiar "Piranha" or "Piraya" for themselves, which means "pirate".
In Germany and Russia, this fish received at all the formidable names: the Germans call this fish, round like a coin, and covered with shallow shiny scales, "silver taler", and we got a nickname "coin" or, depending on the size of the ruble "," Grivennik "and so on. The Spaniards also call this fish "Cariba", that is, "cannibal", because, quite a cadence, Piranha attacks his smaller fellow comrades.
Unsurpassed vitality of pirands
In general, for piras to eat a piece of a friend - the usual thing. Already barely grown fish (1.5-2 centimeters in length) are already torn apart pieces of meat. At the same time, despite the acute teeth, it does not reach the murder. Hungry Pirana need quite some meat to quench the hunger, therefore, catching a piece of a neighbor, it usually calms down. And the victim soon recovers, because Piranhas have an amazing ability to regenerate, and they grow off the pieces of meat again.
