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.


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”.

To begin with, the aquarium should be positioned correctly, as this is important. It is best to place it in a well-lit and quiet place. Capacity dimensions also matter, the bigger the better.

Predatory aquarium dwellers require optimal water parameters, the joint keeping of cold-water with warm-water fish is not allowed. Water should be saturated with oxygen in sufficient quantities, as well as important filters and aeration.

As a decoration of the water landscape, you can use snags, stones, algae, pots. Plants are needed with large roots or planted in a pot, suitable broadleaf sagittariya and ekhinodorus.

Cichlasomes and Akaras are the easiest to keep, while smaller cichlids require skills and experience in keeping aquarium fish. In no case should you put a hand with fresh cuts into the aquarium, as predatory fish can attack and cause serious damage.

Basically aquarium predators are unpretentious in care and rarely get sick.

Blue discus

Many aquarists get their predators. In this case, the most common mistake – the selection of predatory fish, together with the peace-loving. Buying a certain set of fish, you must first of all be aware of their compatibility.

If there are goldfish in your tank, predators will simply eat them. It should also be remembered that acquiring for the aquarium very different in size fish, you are at great risk, even peace-loving fish can eat small individuals.

Let us consider in more detail the most common types of aquarium predatory fish.

These predatory fishes belong to the order of perciformes. Aquarists love them for a beautiful bright color and unusual behavior.

These fish have high intelligence and can recognize their owner, react to the movement of their hands and observe life outside the aquarium.

These fish are predators under natural conditions, they are as long as 20 cm, and in an aquarium they grow up to 15 cm. Their bodies are oblong, dark blue or bluish in color.

The presence of eight transverse bands is obligatory. The eight-band cychlasma is very aggressive, therefore it should be contained in a species aquarium that is not less than 90 cm long, large flat stones and sandy soil.

Plants in the aquarium, to withstand the attacks of fish, must have a strong root system. In a small amount they need to give finely chopped liver and beef meat.

These predatory aquarium fish have a long oblong body 20-25 cm. For their maintenance requires a large aquarium of 400 liters. A distinctive feature of the krenicichla is a dark longitudinal stripe, as well as black spots on the sides.

They feed on small herbivorous fish, amphibians and crustaceans. For normal digestion, a predator needs fiber.

Most often they attack from ambush at fish, which violated their territory, including their relatives. In the aquarium it is desirable to have snags, various caverns and aquarium plants – this will help to choose a shelter to your taste.

This fish is also called Oscar. Under natural conditions, the length of her body can reach 35 cm, and in an aquarium, 25 cm. Her oval body is slightly flattened at the sides, the forehead is large and convex, and at the base of the tail there is a black spot called the “false eye”.

These are the most common predatory fish for the aquarium, especially albinos and red individuals of astronotus with white fins. This predator is unpretentious in content, but it behaves rather aggressively with its neighbors.

The volume of the aquarium for them should be at least 200 liters. They feed on live food or its dry substitute.

This is a small fish with large eyes, bulging and up to 10 cm long. Its head smoothly flows into a short rounded body.

A distinctive feature of this individual is that, at the slightest danger, it can “inflate” its body. You can enrich the diet of these fish with finely chopped liver, heart or beef.

Be sure to select in the aquarium a place where the tetradion can lie low, otherwise it will become overly aggressive towards its congeners.

Of course, aquarium piranhas are not as bloodthirsty as their wild relatives. They have lost their aggressiveness and do not represent danger to humans. Matriarchal reigns inside the pack, where “extra” relatives are simply killed.

Aquarium for flocks must be at least 400 liters. The lack of space will immediately make these fish more aggressive towards each other or the rest of the fish.

Neons, guppies and other small fish are suitable as neighbors, piranhas do not pay any attention to them. You can feed them with earthworms, finely chopped meat, sea fish and shrimps.

Despite their reputation, aquarium piranhas are very shy, they can faint from a flash of light and loud sound, so it’s better to place the aquarium in a quiet place.

Aquarium fish – the most convenient type of pets. Such a living corner will decorate your room and does not take up much space.

There is a large variety of aquarium fish.

In size, small and large fish are divided. Big fish – decoration for the aquarium.

Watching such species as tiger oscar, Moorish idol, surgeon fish, clown triggerfish, cichlids is a great aesthetic pleasure. They live much longer than small fish, but also require special care.

By habitat emit fish for saltwater aquarium and freshwater. The marine aquarium is inhabited by such handsome men: Chinese perch, lion scorpion, fiery angel, zebrasome and others.

The maintenance of these fish has some difficulties, but with the current level of technical support, marine aquariums are gaining popularity. Fish for a freshwater aquarium are represented by such specimens as: discus, lion-headed cichlid, knifefish, goldfish, cichlase-severum.

They are no less beautiful than the sea. And their content is much simpler – just right for a beginner.

The temperament of the fish is divided into peaceful and predatory. Peaceful fish for an aquarium have a timid temperament, live collectively, it is better to acquire them in several pieces.

Such individuals include: guppies, blue, red or black neons, fiery tetras, honey gourami, phylomenes.

Among the predatory inhabitants of the aquarium are: tsikhlasoma, spinoper, astronotus, piranha. They have an aggressive nature, and can not get along with all the inhabitants of the aquarium. For example, piranhas do not strictly get along with the rest of the fish.

Predatory fish grow quickly, for living they need an aquarium of at least 300 liters.

There are fish that come to the aid of cleaning the home mini pond. These fish cleaners are useful inhabitants for an aquarium. These include soma, primarily antsistrus and herinokhaylus.

They eat plant food, have a suction-mouth, eat plaque and fouling on surfaces.

Before you get the fish you need to learn all their features and compatibility. Some individuals like to be at the bottom of the aquarium, others hide in the thickets. The best would be to combine fish that prefer different layers of water, so you can fill the entire space of the aquarium.

Breeding aquarium fish will allow you to have an island of wildlife in the apartment, which will give joy and peace.
