Fans of aquarium fish are special people. Not everyone is given the love of these representatives of an alien world. But I personally like to watch their life, perhaps, to all. In any case, the person who turned his gaze to the aquarium, will not remain indifferent to the hovering fish, like in weightlessness, behind the glass. They say that such contemplation is useful for mental and physical health, and the fish tank itself acts as a feng shui mascot, and as a fashionable and stylish piece of furniture. So if you for any reasons decided to put an aquarium at home and breed fish, then you will need an instruction, according to which you will have to look after the fish. And this is the case, we note the troublesome, but it's worth it. Unfortunately, the instruction for the care of fish is not attached to the aquarium and to the fish themselves. Therefore, learn to care for fish have, based on the experience of seasoned aquarists and special benefits. We offer you a set of rules that will facilitate your care of the aquarium and the fish. 
Choosing an aquarium and fish
You will have to look after not only the fish, but alsofor the aquarium itself. So think carefully about whether you need to immediately buy a too large aquarium or for starters it is necessary to do a little. In general, the size and arrangement of the aquarium directly depends on how much and what kind of fish you are going to contain in it. And, on the contrary, if you already have an aquarium of a certain size, then you need to purchase fish of the same size. In addition, it must be remembered that for the maintenance of some species of fish you need an aquarium equipped with grottos and all kinds of shelter. This is especially important for fish, leading the bottom life. And if you already have an aquarium, then you need to choose fish, primarily based on its size. If the aquarium is small, then the fish in it should live small. But a large and spacious aquarium can accommodate not small aquarium fish, or a large number of small fish. Buying aquarium fish, consult about the necessary conditions for them: water temperature, its hardness and acidity, the need for aeration, filtration and the frequency of water changes in the aquarium, and also about how and how often to feed the fish. Important information will be information about how peacefully can coexist in your aquarium fish you like. Find out if there is a risk of predatory attacks on one type of fish on another, and whether any fish needs special care. Together with the aquarium and fish, you will need to purchase algae and additional equipment that will help maintain the microclimate in the aquarium and make it easier for you to care for them and for the aquarium. 
What is the care of fish?
By and large, any instruction for the care of aquarium fish would contain a list of necessary measures and actions on your part, namely:
- creation of comfortable living conditions;
- support of microclimate parameters in the aquarium;
- feeding;
- inspection;
- cleaning the aquarium.
Additional measures include treatment of fish. Such withdrawal, of course, is a compulsory measure, but quite possible: aquarium fish (like all living things) are susceptible to various diseases. Therefore, your diseases do not exclude such ailments as all kinds of infections, infestations (parasite infestation), ulcers, tuberculosis, as well as specific diseases of aquarium fish. Treatment, as a rule, reduces to isolation of the sick individual and addition of medicines to the water. However, with good care and proper maintenance, most aquarium fish remain healthy all their life. And what kind of care should be, we will consider a little more.
Habitat
Your aquarium is a closed ecological system,habitat of fish. If you maintain the necessary parameters for this fish environment, they will feel comfortable, can avoid many diseases and will not give you additional trouble. How to care for fish from this point of view? What you need to do to maintain comfortable conditions for the existence of your aquarium fish?
- Every day you need to check the temperature of the water and maintain exactly the temperature that is required for a particular type of fish.
- The water must be aerated and filtered. For this, there is a special equipment.
- The state of water is affected not only by its purity, butand the composition, which largely depends on the living aquarium plants. For full-fledged growth and photosynthesis, aquatic plants need light, which, however, is necessary for fish. Therefore, from time to time and depending on the duration of daylight, you need to turn on the illumination of the aquarium.
- "Bad" can make water substandardaccessories for the aquarium, made of plastic and tobacco smoke. So do not skimp on cheap embellishments and do not smoke (do not let it others) near the aquarium.
- Periodically pour fresh water into the aquarium and periodically clean the aquarium itself.
As experienced aquarists advise, completelyTo replace water in the aquarium should not be. If you need to change the water, you just need to remove dirt and debris from the bottom of the aquarium, merge two-thirds of the old water and pour fresh water, which should be the same temperature, stiffness and acidity as the previous one. 
Feeding
This is the second important point from the general rules,determining the daily care of fish. Usually adult aquarium fish are fed once or twice a day, and fry is fed four to six times. Which kind of food - dry, live or frozen - fits your fish, depends on their kind. But, as a rule, they feed the fish with different feeds and choose the one that they eat more readily. It is important to determine the volume of feed, because you can not overfeed the fish, but you do not need to be hungry too. The exact amount of fish food depends on the size and number of inhabitants of your aquarium, so you will have to determine it yourself. To calculate the optimum volume of feed, the first time you need to observe the fish. A suitable "portion" will be the amount of food that fish can eat in five to ten minutes. If, at the end of this time, the fish stopped eating, and the food is still left, then you have poured more. These surpluses must be removed from the aquarium. If the fish ate all the food in five minutes and continue to look for what else to profit, it means that the portion you poured was too small.
Preventative inspection
Strangely enough, but to take care of the fish inThe aquarium is also needed by conventional observation. In addition to monitoring the state of water, you need to inspect the fish and plants every day. Decaying aquarium plants must necessarily and immediately remove, and fish with signs of disease must necessarily be isolated. Here's what you should be alerted to in appearance and behavior of fish:
- wounds, ulcers and outgrowths on the body;
- standing on end of scales;
- plaque and noticeable spots on fins and tail;
- excessively bulging eyes;
- cysts (white translucent grains) on the scales;
- Depressed state and depleted species of fish.
Such fish should necessarily be planted in anotheraquarium, quarantining them. How to treat fish, it is necessary to consult a specialist, as it is quite difficult to diagnose a novice aquarist independently. And isolation is necessary so that the disease is not transmitted to other fish. General cleaning in the aquarium (if care for fish and for the aquarium itself is correct) is quite rare. However, if such a need arises, the fish are transplanted into another aquarium, drain the water, clean the walls, the bottom and the water filter. Then in the aquarium pour clean water and run fish there. Of course, different types of aquarium fish require different conditions of detention. However, the novice aquarists will come in handy with our brief instructions with a set of general rules for caring for fish. Remember that fish are living creatures and need your attention and care, and let this care for you is not burdensome. Good luck! We advise you to read:
