The content of aquarium fish
In Zoological shop sells aquariums, varying in shape and size: rectangular, cylindrical, spherical. For keeping and breeding fish is considered to be a convenient rectangular all-glass aquarium. Many people make themselves decorative aquariums-pictures, aquariums-screens, etc.
To do this, take corner of sheet iron, glass, putty. Metal corner make a rectangular frame, insert the bottom and sides of glass. Then cover the cracks with special putty. Check the aquarium for leaks. Putty you can prepare yourself.
To do this, take two parts of dry sifted chalk, one part of red lead, mixed with hemp linseed oil to the consistency of thick putty, or 1 kg of drying oil oksol, heated to 60°C, adding 0.2 kg of bee wax, 2 kg red lead or gustotertoj paints. All components mix thoroughly and gradually add the chalk or tooth powder until the desired consistency. Set the aquarium on a well-lit area. If there is no such place, for artificial lighting, use fluorescent lamps or incandescent lamps. Lighting the aquarium should be from 8 to 21h. It is not recommended to set the aquarium on the windowsill, where frequently changing light conditions and temperature.
For aquarium maintenance preoperational:
— feeder fish;
— nets of various dimensions;
— a hose with a nozzle to remove the precipitate;
— lamp with reflector for highlighting;
— electric heater for heating water;
a spare aquarium;
— banks for depositing fish;
— magnifying glass to view the live feed.
As use of soil coarse sand or gravel 2-4 mm in diameter dark in color. The soil is used for fastening plants and serves as a good background for fish. Before you fill up, the soil must be washed and boiled. Looks spectacular aquarium with a terrace. For this purpose it is necessary to put more soil in one of the corners and hold the glass strip. In such an aquarium can be planted in clumps of several plant species. Often in the aquarium soil is poured with a slope to the front glass to make it easier to clean with a hose accumulating impurity.
In laid on the bottom of the aquarium ground planted plants. Before they can be disinfected by rinsing in a solution of potassium-aluminum alum (alum teaspoon on 1 l of boiled water), then rinse the plants in clean water. Rasasi planted directly in the ground or in ceramic pots with holes in the bottom. If the capacity of the tank does not exceed 10-20 L. it is best to plant plants in pots. In large aquariums plants are planted directly into the ground.
The bottom of the aquarium even decorated with rocks and driftwood. Driftwood is recommended to cut out dead willow trees. Their pre-digested 12 hours in salt, then in fresh water. After planting and installation of decorations aquariums filled pooled water. Water for the aquarium settles in enamel bucket or glass jars at least 3-4 days. During this time, the deposited impurities and smell of chlorine disappears. A water filled aquarium for a week to stand without fish.
Under the influence of biological processes between water and plants the water becomes cloudy immediately, but after a few days she becomes pure and transparent. If the plants have taken root and feel good, you can run fish. For different aquarium fish species require a specific aquatic environment: appropriate hardness, acidity, temperature. The stiffness depends on the content in water of salts of calcium and magnesium.
Distilled water can be replaced by rain or snow. Soften water in other ways: by long boiling and sedimentation, and by using the ion filter. To increase the hardness of the water should be boiled, to defend and to use the lower third of the sludge by adding a solution of chloride of calcium and magnesia. It is very important to maintain the aquarium desired level of acidity (pH). Distinguish a neutral — pH 7 acidic — pH below 7 and alkaline — pH above 7. The acidity is determined by the concentration of hydrogen ions in water pH scale:
strongly acidic water is from 1 to 3;
sour water from 3 to 5;
slightly acidic water is from 5 to 6;
very weakly acidic water is from 6 to 7;
neutral water is 7;
very slightly alkaline water — from 7 to 8;
alkaline water — from 8 to 9;
alkaline water — 9 to 10;
strong alkaline water — from 10 to 14.
Acidified water, infusion of alder cones, infusion or extract of peat, hydrochloric, phosphoric or phosphoric acid or finished drug “Tetra Toru Min”. The acidity (pH) in the aquarium is determined using indicator paper or more accurately electrical pH-meters.
You must carefully monitor the cleanliness in the aquarium. Promptly remove the rotten leaves of the plants, cleaned the bottom, to adjust the amount of feed consumed, given its quantity, to clean the filters and adjust the temperature. Depends on the oxygen content in the aquarium. Indicators that determine the lack of oxygen in the aquarium are live-bearing snails Melania and fish black mollies. Melania climbs from ground to glass and wood, and mollies are swimming at the water surface. The lack of oxygen in the aquarium aeration add artificially.
The most important condition for the maintenance of the fish in the aquarium is temperature.
For most exotic fish water temperature should be 22-25 °C. Heated water in aquariums of various heaters that are sold in pet stores. For water purification use filters of various designs — foam exterior and interior, plastic filled with nylon wool. Without plants, it is impossible to imagine the aquarium. Nothing adorns it, like plants. In addition to the fabulous beauty that is created in the aquarium, they reduce stiffness and enrich the water with oxygen, are spawning substrate for tossing caviar, serve as refuge for fish and a kind of filter for the purification of water.
Without plants the fish sick and often die.
Some plants serve as food for fish. Aquatic plants are divided into floating on the surface and in the water column, as well as rooting in the soil.
The first group includes:
— water hyacinth (eichornia),
