Predatory aquarium fish
Quote: “Who wants to live – he must fight. And who does not want to resist in this world
the eternal struggle, he has no right to life. “
Dear reader, this article is devoted to predators of the freshwater aquarium. On the Internet, there are a lot of tales about this issue, to the extent that the Angelfish are ferocious predators of the aquarium.
Therefore, before you lay out our selection of predatory fish, let’s determine with you in terms.
All animals can be divided into predators and herbivores:
Predatory – These are those who eat only meat.
HORROWAYS – These are those who eat only plants.
Now it is worth noting the fact that in nature it is very rare to find a PREGNANT ANIMAL, which feeds exclusively on meat. For example, cats!
Cats are predators, but all happy owners of Barsik and Murzikov know that their pets love to chew grass and home plants.
The same situation is with the fish. In the huge aquarium kingdom it is very difficult to find a meat-eating fish.
Perhaps this is not. I do not renounce, but the diet of all aquarium fish includes both vegetable and animal feed.
From the above we can conclude – Of predatory aquatic fish in the true sense of the word does not exist. Speaking of the predatory nature of fish, the word aggression is most likely appropriate.
But with aggression there is its own catchup – after all, even guppies show intraspecific aggression, although they don’t pull on predators at all.
Thus, it is possible to deduce a certain vector of understanding of the phrase: “PRIVACY AQUARIUM FISHES” – these are excessively aggressive, large, territorial aquarium fish, in the diet, which mainly includes meat food.
SELECTION OF PREDICTIVE AQUARIUM FISHES (with photo and description)
Many people know that the family of cichl fishes are for the most part aggressive, territorial fish, especially this statement applies to African cichlids. In some species of cichlids, there is even the most severe intraspecific aggression, which is manifested not only in males in relation to each other, but also between the male and female, for example, as in Labeotrofeus Arevavas.
Sometimes it comes to the fact that the joint maintenance of the female and the male becomes simply not possible, since the latter slaughters an individual of the opposite sex to death.
Astronotus – the most popular and common cichlid, having a predatory disposition. Large, aggressive fish, which is best kept in the species aquarium and a pair.
Astronotuses are perceived by all small neighbors as food. And with large species, clashes occur constantly.
For an adult couple, it’s almost unreal to plant someone.
Fish can reach 35 cm. Astoronthus is the birthplace of the Amazon, the system of the rivers Paraná, Paraguay, Rio Negro.
The volume of the aquarium for such tsikhlin need from 300 to 500 liters.
Water parameters: pH 6.0-8.0, temperature 22-28 ° C. Of course, aeration, filtration, and regular water changes (weekly 30%) are necessary. Particular attention should be paid to filtering – it should be powerful (the second filter will not be superfluous).
The aquarium can be decorated with large stones and snags, the decor should not be sharp.
CYCHLIDE KNIFE Haplochromis long-nosed
It has a territorial character and is jealous of those who come to its territory. Long-range cichlus rushes to various shiny objects. In clashes with other fish catches the eye, for which he received the nickname “eye eater”.
These fish in nature are fierce “killers.”
Comfortable parameters of water: temperature 25-27 ° C, dH 8-20 °, pH 7.5–8.5. aeration, filtration, weekly substitution? parts of fresh water with the same parameters.
Piranha predators are literally armed to the teeth. Teeth lamellar and sharp as a razor.
Piranha’s jaws are powerful, an adult can bite a wooden stick as thick as a human finger.
It should be noted that aquarium piranhas lose their natural aggressiveness, while maintaining their formidable appearance. But for some reason people’s fear of this does not disappear.
Piranhas are a great aquarium fish, therefore it is better to keep them with a school of 5-8 fish of the same size and age.
These somas are not just predators, but “fierce killers”. In their homeland, in Asia, they exterminate all the fish that are in their reservoir, and when there is no one left, they crawl out onto dry land and crawl to the nearest new reservoir for the “new victim”, while at the same time eating on land »Insects and small frogs.
We must pay tribute – in the aquarium, these somas behave much calmer.
The fish is not livable grumpy character, shows aggression. You can keep a tetradon with large mobile fish.
Some authors recommend keeping this fish only in a species aquarium.
For a flock of tetradons you need a large volume of aquarium from 150 liters. Fish leads a twilight lifestyle and is afraid of bright light.
Therefore, the aquarium is equipped with a variety of stones, caves, snags and floating plants.
Toward the close of the article, I will give an example that clearly shows the rapacity of any living creature, even the most innocent.
Akantoftalmus – a small loach wormfish. Peaceful harmless inhabitant of the aquarium bottom. But…. in nature, if an acantophthalmos is caught by a medium-sized predator, a sharp spike will cause it to immediately spit out and remember this striped fish.
Big birds or catfish often swallow Acantophthalmos completely. What, very much regret.
A small fish breaks through the stomach wall of the animal, and sometimes goes outside. The obscene predator dies.
The struggle for life, alas, many forces to be predators and cold-blooded killers. And the world of aquarium fish – this is just a small springboard for fighting for life and procreation.
We also recommend you to look at the colorful brochure “Popular types of aquarium fish”. This brochure contains all popular types of fish, with a description of their conditions of maintenance, compatibility, feeding + photos.

There are a lot of species of fish considered predatory. However, almost all carnivorous representatives of aquatic fauna consume at least a little and food of plant origin. With a few exceptions, this happens both in nature and in aquarium conditions.
That is why the definition of “predatory” most often means “fish that feed mainly on live food and are distinguished by a high degree of aggression”.
Most aquarists, especially beginners, prefer to keep small herbivorous fish at home. It is believed that they are less troubled, they rarely attack each other, and there are no special problems with food.
This is true. However, there are a considerable number of owners of predatory fish, for whom their exotic wards are subjects of particular pride.
To keep carnivorous big fish is not easy; they require special attention, but it is very interesting to observe their development and existence in the aquarium.
It should be noted that for most of the predators, the home aquarium environment is far from natural. It is no secret that in the conditions of a small artificial reservoir they do not grow to their natural size, their diet varies somewhat.
However, the predatory disposition remains unchanged, and if such a carnivorous hunter feels hungry, it does not cost him to attack his neighbor.
Feeding predatory fish should be made taking into account many factors. If you want to look at the process of hunting, then you can from time to time launch “feed” live fish purchased at the pet store into the aquarium.
The diet of predators can include raw meat or fish fillets, shrimps, large worm and other protein foods.
The frequency of feeding is also different. There are predators who swallow their prey entirely; they are usually fed 2-3 times a week.
In almost all other cases, twice a day feeding is organized without overfeeding.
The main feature of the content is, of course, the size of the living space.
In any case, before you get such a cute fish, you should study its habits and conditions of detention.
Exotic bloodthirsty inhabitants of South American rivers – this is what is usually known about the piranhas to the ordinary man in the street. However, these representatives of the Kharacin family also live in Mexico and the USA, they are also found in Europe (Spain), some species have acclimatized even in the south of the European part of Russia.
The ominous fame of piranhas in many ways created Hollywood with his horror films about the bloody attacks of these predators on the people. However, piranhas have long been firmly established in aquariums around the world; their popularity among Russian aquarists is growing.
Piranhas are exclusively schooling fish, in nature reaching solid sizes: 50–70 cm in length. However, in captivity, their growth is limited by the size of the aquarium and rarely exceeds 30 cm.
The body of these charicin is ellipsoidal, strongly compressed laterally.
- A “dwelling” for piranhas selects 100 liters of water for 1 individual. Therefore, a 500-liter aquarium is needed for a flock of 5-6 individuals.
- The purity of the water and its oxygenation is very important! Requires the installation of a powerful external filter and compressor.
- The temperature of the water should be maintained within 22–26 ° C above zero, its sharp fluctuations should not be allowed.
Piranhas are usually fed with earthworms, clams, raw meat, squid, and pipemaker. You can run small guppies and swordtails, and then watch the process of hunting.
Predators eat a lot, but do not overeat. After they are saturated, the remnants of the feast should be removed.
And do not be afraid to lower your hand in the aquarium: well-fed piranhas will not bite you!
Cichlides are becoming more and more popular every year. Carnivorous cichlids also require increased attention during maintenance, as they can engage in fights even with congeners.
An example of an aggressive African cichlid is the hawklochromis long-nosed or fish-knife. This predator of relatively small size (10–13 cm) furiously rushes at smaller fish.
- These cichlids live in small flocks, where there is a pronounced leader.
- Eat dry, frozen or live food for cichlids.
- The temperature of the aquarium water should be in the range from +25 to +28 degrees, the acidity is neutral, the hardness is from 10 to 20 degrees.
The predator, whose distribution area covers East Africa and Asia, is not very popular in domestic aquarism, although it deserves it.
Beautiful coloring (large black spots on a bright green background), bulging big eyes and the seeming slowness of this rounded fish seem to mask its predatory disposition.
- The skin of the tetradon is very thick, without scales, there are several thorns on it, which the predator raises in case of danger.
- The abdominal fin is absent, but very strong pectoral fins allow individuals to move quickly or hover in one place.
- The jaws are very strong, and instead of the teeth there are four plates that grind the prey that fell into the mouth.
- The size of the fish usually does not exceed 17 cm, the life span is about 10 years.
Another predatory species that lives in a vast territory from India to Indonesia. In English-speaking countries, he received the name “walking catfish” for its ability to crawl from the pond into the pond in search of food.
The oxygen content in the water is not so important, since this voracious predator can breathe for some time and atmospheric air, filling them with their side bags.
This catfish is almost omnivorous; with great pleasure he swallows the pipemaker, fish fillet, beef heart and liver, pieces of squid.
It is better to keep a pair of these predators in a species aquarium with a volume of at least 200 liters, since individuals can grow up to 0.5 m in length. Layer of soil should be poured thicker, as the naughty Clarius likes to dig into it.
It is clear that aquarium decorations must be firmly attached, but the aquarium itself must always be kept closed.
The predatory and aggressive catfish is not without intellect: it recognizes its owner and, being in a good mood, can afford to stroke. In general, quite a pretty creature.
Keeping flesh-eating aggressive fish is difficult and costly for the family budget. However, this is a very exciting experience, giving experienced aquarists a real pleasure.
Predatory fish aquarium make home aquarium exotic. There are many types of predators.
The larger the size of such fish, the more interesting it is to watch them.
These fish deliver much more trouble than the usual “peaceful” fish. Before buying predators, experts advise to carefully weigh the pros and cons.
Predatory fish in the aquarium require close attention. They constantly show their natural instincts.
The most popular are piranhas, cichlids, girinohaylusy and fish with the strange name “Indian Ocular Knife.” In very large aquariums often snakeheads are bred.
Under natural conditions, large individuals reach 1 meter in length and their weight can be 7 kg. Such fish look very colorful.
Together with snakeheads, you can only keep big fish, such as polypteruses, tarakatums and astronotus. Otherwise, the predator just swallow them.
Some species of fish may exhibit intraspecific aggression.
The frequency of feeding depends entirely on the type of predator. Environmental factors also matter. Many fish in nature eat food continuously.
In aquarium conditions, fish can be fed several times a day. At the same time it is necessary to give small portions of food.
Some predatory fish in the aquarium can swallow large prey entirely. In this case, they are fed no more than three times a week.
Sometimes they themselves refuse extra food. Below is a video of feeding predators aquarium fish.
Predatory aquarium fish need a large aquarium with an optimal water temperature. The composition of water also matters.
The larger the individual, the more space it needs. You can not keep in the same aquarium cold-water and warm-water fish.
In addition, home water should be equipped with a filter. There should be enough oxygen in the water.
Attention should be paid to landscape design. Algae, snags and pebbles can be placed in an aquarium.
The maintenance of predatory aquarium fish is a fascinating activity that brings a lot of pleasure.
These fish are sometimes called false discusses – they resemble the kings of an aquarium with body shape and gorgeous coloring, as well as aristocratic behavior. But the severum is much less demanding in conditions of detention, more resistant to pathogens and stress factors.
These reasons largely determine the interest that aquarists have had for them for many years.
Severums are a species (according to some authors, a group of species) of South American cichlids, which are fairly large in size (in aquariums usually 15–20, sometimes up to 30 cm), tall, flattened laterally and in many ways. Some of these color forms are derived by breeding, others are species found in nature in different localities, therefore they are named after these places.
