Zebrafish will die if the water temperature is lower than 10 ℃. Although they are tropical fish, they have certain cold tolerance and can survive even in the water temperature between 11-15 ℃. Although they can grow in water temperature between 11-15 ℃, if they grow in low temperature environment for a long time, their growth state will be affected, their growth speed will slow down, and they will be prone to illness. If the breeder wants to make the zebrafish grow better, it is best to install a heating rod to keep the water temperature constant.

Zebrafish are tropical fish and prefer warm environments. However, the acceptable water temperature should not be too high. If the water temperature is higher than 35 ℃, they will also die.

As mentioned above, zebrafish can grow in the water temperature between 11-30 ℃, and breeders can grow normally as long as the water temperature is within this range. But if breeders want them to grow better, it is best to keep the water temperature between 24-26 ℃. Because in this temperature range, their growth state is the best, their food intake and activity are also the highest, and their growth speed will naturally be faster. If conditions permit, a heating rod can be installed to keep the water temperature between 24-26 ℃.

Zebrafish is mild in character and has low requirements for the environment, so it is more suitable for breeding as an ornamental fish. Breeders usually only need to ensure that their living environment is comfortable and stable, and there is enough food and oxygen, so they can grow well.
