The fauna of the Black sea is markedly poorer than the Mediterranean sea. In the Black sea is home to 2.5 million species of animals (including 500 single-celled species, 160 species of vertebrates — fish, mammals, 500 species of crustaceans, 200 species of mollusks, and the rest — invertebrates of different species). for comparison, in the Mediterranean — about 9 thousand species.
Among the main reasons for the relative poverty of fauna of the Black sea: a wide range of water salinities, moderately cold water, the presence of hydrogen sulfide at high depths. In this regard, the Black sea is suitable for habitation fairly undemanding species, at all stages of development which do not require great depths.
At the bottom of the Black sea inhabited by mussels, oysters, pecten, and the mollusc-predator Rapana included with vehicles from the Far East.

Often contain well-dressed inhabitants of tropical coral reefs. It is interesting to contain cold-water marine life. Such an aquarium should be in the summer especially cool.
Sea water is prepared artificially by division or from commercially available ready mixes for marine aquariums. It must have a salinity of 30-35‰, pH of 8.0 to 8.4, temperature depending on the content types. You need a constant control of temperature, pH, density (measured by hydrometer) and water salinity.

Underwater world: sea animals and fish Turkey
It is hardly possible to find a country like Turkey. Its shores washed by the water of four seas. The black sea in the North, Aegean in the West, the Marmara in the North-West, and the Mediterranean sea to the South. Each sea with their inhabitants and their character.
