Predatory aquarium fish attract aquarists for their uniqueness, because most often people plant mainly herbivorous or omnivorous species. People have formed the image that predatory fish are aggressive species that are constantly trying to fight, to get into a skirmish.
They necessarily have territorial inclinations, and they carefully protect the chosen territory from any encroachment.
These qualities are present in some species, but they are not in all predators. Among them are peaceful fish.
And small viviparous fish like swordtails and guppies can also show aggression and pugnacious character.
It is impossible to attribute any species completely to herbivores or predatory fish. Most fish alternately consume meat and vegetation in their diets.
Any carnivorous fish needs vitamins and nutrients contained in plants. But among the predator fish, there are families of Tsikhlovs, Piranyevs, Somovs and Snakeheads.
These families include hundreds of species of fish that differ in size and character.

The aquarium for predatory fish is selected taking into account the length of their body. Most predators grow from 20 to 50 cm, which means that the size of the tank needs roomy.

For most aquarium predators, a powerful filter in an aquarium is needed, because high pollution is harmful for some species.
Together with predatory fish, the aquarium usually contains the same carnivorous. Herbivores are shared only under the condition that their body size is the same or larger than the body of predators, otherwise they will become food.
But the best choice would be to keep one predatory species apart in a separate tank.
When spawning approaches, predators in the aquarium become even more aggressive. To reduce nervousness and stress, be sure to set up a separate spawner for a pair of fish.
Feed fish with high protein foods.

The maintenance and care of aquarium predatory fish has its own difficulties and is usually not advised to beginners. But with careful care you get nimble pets with a great mind, who will delight in their coloring and behavior.
