Aquarium fish

Fish are the most ancient animals on Earth: they appeared more than half a million years ago. However, the first ocean fish was different from today, as they were deprived of jaws and scales. Then the fish moved with the help of the tail because the fins they had. But, as we know, time is not standing still. Everything in the world is improving. People learned to make clothes, build houses, domesticate animals and to grow. In this article I would like to tell you about the fish. There are different marine fishes, for example the well-known herring river, for example, carp or pike, and the aquarium, for example gourami …

Today, there are many ways of breeding fish. The most popular is the breeding of fish in aquaria. The aquarium can be different in shape, design, size. We can see it, as a piece of furniture: cafes, restaurants, country houses or just at home. You can sit for hours and look at him, plunging thoughts and fancies in water world. What fish are varied, some bright, colorful, large; others are small, delicate and a little cowardly.

Let’s talk about the varieties of aquarium fish. Scientists have come up with a classification that divides fish into families, types, species, subspecies. Sushestvenno the names of the fishes. Some live in fresh water (guppy, swordtails, barbs, angelfish), others – in the Maritime (clowns, gobies, angelfish, seahorses).

There are fishes which are viviparous, for example, striped Jenny for all nutrients between the fry and the mother the placenta is formed; and there are those that spawn (males, angelfish). Some fish are carrying eggs in the mouth (chocolate gourami). There are fish with teeth that are constantly updated (piranhas, catfish).

Fish also differ by sex: female swordtails are considerably larger than the males, but the males grow tail on the “arrow” that you can’t see the females. Guppy males – bright in color with beautiful colored tails.

You can tell a lot about these amazing creatures — fish. If you are stressed, you can just look at the fish that swim in the aquarium, and you calm down. But while the man himself does not see, does not know or feel the whole magic of the underwater world, he will not be able to understand how nature is related to us, how we are addicted to it!
