Predatory aquarium fish

Quote: “Who wants to live must fight. And who doesn’t want to resist in this world
eternal struggle, he has no right to life”.
Dear reader, this article focuses on the predators freshwater aquarium. Online wanders a lot of tall tales on the subject, to the extent that Angelfish is fierce predators of the aquarium.
Therefore, before to lay out our selection of predatory fish, let us define the concepts.
All animals can be divided into carnivores and herbivores:
CARNIVOROUS – those who feed exclusively on meat.
HERBIVORES are those who eat only plants.
Now it is worth noting the fact that in nature is very rare to find a PREDATORY ANIMAL that eats only meat. For example, cats! Cats are predators, but all the happy owners of Barsik and Murzik know that their Pets love to chew grass and house plants.
Same situation is with fish. In a huge aquarium the Kingdom very hard to find “fish masueco”. Perhaps that would not. Do not renounce, but in the diet of all aquarium fishes includes both plant and animal food.
From the above we can conclude – PREDATORY AQUARIUM FISH in the true sense of the word does not exist. Speaking of chasnosti fish most likely appropriate the word aggression. But aggression has its own trick question – after all, even guppies exhibit intraspecific aggression, although predators they by no means pull.Thus, it is possible to deduce a vector of understanding the phrase: “PREDATORY AQUARIUM FISH” is overly aggressive, large, territorial aquarium fish, a diet which is predominantly meat diet.

Sometimes it comes to the fact that the joint content of female and male is simply not possible, as, the last to death scores individual of the opposite sex.

aquatic predators, piranha
Piranha predators are armed literally to the teeth. The plate and teeth sharp as a razor. The jaws of the piranha fish is powerful, the adult may chew on a wooden stick thick as a human finger.

aquarium predatory catfish
These catfish are not just predators, and “cruel killers”. In their homeland, in Asia they are destroying all the fish that is in the reservoir, and when no one remains, they crawl out onto land and crawl to the nearest new reservoir for the “new victim”, and at the same time, on land eating Popeye “arm” insects and small frogs. We must pay tribute – in the aquarium these catfish behave much calmer.

Akantoftalmus – small loaches fish-worm. Peace harmless inhabitant of the aquarium bottom. But…. in nature, if acanthophthalmus catch carnivore of medium size, a sharp spike will cause him to immediately spit it out and remember this striped fish. Large poultry or catfish often swallow acanthophthalmus entirely. What, then very sorry!!! Little fish breaks through the wall of the stomach of the animal, and sometimes goes out. Gourmand predator killing.
