In addition, feed should be used in combination, and single feed can easily lead to inadequate nutrition of fish.
The size of the fish is also related to the fish tank, if the fish tank is relatively small, the fish can not open, will also lead to it become an old fish. Therefore, it is necessary to choose a suitable fish tank according to the size of the fish, so that it has sufficient swimming space. In addition, the breeding density in the tank can not be too large, on the one hand, this will affect its activities, on the other hand, it is easy to cause fish hypoxia.
If a fish suffers from a disease during its growth and cannot be cured for a long time, it will delay its development and become an old fish. Therefore, when the fish is found to be uncomfortable, it needs to be treated in time. The common treatment is the old three, that is, changing water, warming up and adding salt. Water can be changed every other day, as long as the temperature is increased by 1-2 C, the salinity of salt is generally three thousandths.
