Not all fish tanks can be used to raise fish. If the tank is not properly opened, there will be all kinds of harmful bacteria in the tank, and it is often difficult to raise fish. In view of this situation, we must re-open the cylinder, soak it with disinfectant solution for a period of time, and re-clean it several times after emptying, so that the cylinder will not have problems.
If the water is not well kept, the fish can not be kept alive. There are generally three aspects of water problems, first of all, there is no trapped water, because fish at home mostly use tap water, water contains residual chlorine, without trapped water treatment, residual chlorine will cause harm to fish. Secondly, the water temperature, the temperature must be appropriate, too high or too low will affect the health of fish. Finally is the water quality, the tank needs to be filtered, otherwise the water quality is muddy, the fish is also very easy to die.
If the fish is sick at the beginning, it will naturally not be able to keep alive. Therefore, when buying fish, you must choose healthy ones to ensure that there are no rotten places on their bodies. At the same time, they will not float or lie in the tank. Such fish are unhealthy. If they are not treated in time, they will basically not be able to keep alive.
The water quality and temperature of fish raised in fish shops are often very suitable, but it may not be possible to raise fish at home, and because of changes in the environment, it is not a small fluctuation for the fish, which may cause some stress reactions, and if not well cared for, they will die, so we must choose some adaptable fish at the beginning. Keep it well and then change it for another one.
