For people who are raising fish for the first time, it is very necessary to open the tank. If the tank is not treated and water is added directly to raise fish, it will generally be raised soon. The first thing to do is to disinfect, the purpose of which is to kill some potential harmful bacteria. The method of disinfection is very simple, as long as the fish tank is soaked in potassium permanganate solution for 3-4 hours, and then washed several times.
Fish need to raise water, water is not well raised will also lead to fish can not live. The first step in raising water is to trap the water, except for the residual chlorine inside, although the content is not high, but it is still a threat to the health of fish. Secondly, attention should be paid to the cultivation of bacteria and the establishment of a good nitrification system, so as to avoid the absorption of ammonia nitrogen poisoning by fish, leading to their death.
If the quality of the fish has problems, no matter how good the water is, it will not survive. When buying fish, we must pay attention to the selection, buy more dynamic fish, do not choose those who do not like to swim, like to lie in the tank or body surface disease fish, these fish are not good to raise. In addition, we should pay attention to the species, some fish are difficult to raise, for novices, it is easy to die.
If you raise tropical fish, you must pay attention to keeping the water temperature. If the temperature is too low, it will cause them to die. Usually, the temperature should be controlled between 20 and 30 degrees Celsius, and the heating rod can be used to maintain a constant temperature to avoid too large changes in temperature.
