. Mary fish itself belongs to a tropical fish. The most suitable temperature for their growth and development is between 22 and 28 degrees. They will develop faster in waters with relatively high temperatures. When Mary fish are sexually mature and enter the breeding period, the temperature of their waters should be raised again, preferably above 25 degrees. Spawning in this environment can increase the hatching rate of their young fish. Moreover, the relatively high water temperature is more suitable for the growth and development of young fish, which can make them adapt to the external environment better and faster.
is the lowest water temperature of Mary fish? Generally, the lowest water temperature of Mary fish should not be lower than 18 degrees. In the case of a heating rod, it is better to adjust the water temperature to more than 22 degrees. Because Mary fish are more afraid of cold, they are very vulnerable to disease in the environment of low water temperature. There may be loss of appetite, not very fond of swimming, if not adjusted in time, it is also very easy for them to suffer from white spot disease, Saprolegniasis and other diseases. Therefore, when raising them, we should pay more attention to the temperature of the water to avoid the occurrence of illness of Mary fish.
