Many aspiring Amateur aquarists strive to keep in the aquarium more vibrant and beautiful fish, oblivious to the fact that you can not find them only in appearance. Survival, development and reproduction of fishes is a complex process. While much will need to be taken into account. For the settlement of the aquarium it is better to take young fish. They are best acclimatized to these or other conditions. When it is difficult to determine the sex, it is better to choose a few big fish and young the same for equal ratios of both sexes. You need to keep in mind that the aquarium can only contain fish of the same volume, the disposition and habits. You cannot put together the large with the small, predatory — with a peaceful, cold-water with warm-water.

In aquariums, if they are blowing off and water filtration, you can keep the fish 2-3 times more, depending on their age and type of aquarium. In low aquariums can contain fish of more than high as the enrichment of water with air, takes place largely on the water surface. The best effect still gives the settlement in a fish aquarium of any one or more types according to the similarity of living conditions and relationship. Widely known for all fish categorized on the basis of species characteristics, lifestyle and method of reproduction.
