The suitable water temperature for Luohan fish is 28-30 degrees, but if the temperature is lower than this temperature, it will not be life-threatening for Luohan fish, but the appearance will become ugly; if the water temperature is higher than this, the fish will speed up. Metabolic speed is not conducive to extending life. Therefore, to breed a Luohan fish well, insulation measures are essential. The best water temperature in the fry stage (within 7CM) is around 32 degrees, the water temperature in the sub-adult stage (7-15CM) is best kept between 29-30 degrees, and the water temperature in the adult stage (above 15CM) is best kept at 27-28 degrees. should not be too high to slow down the metabolic rate and help adult fish extend their lifespan.

How Luohan fish controls water temperature:

Luohan fish is a tropical fish. It has relatively high requirements for water temperature and its adaptability to water temperature is relatively small. When the water temperature is below 25 degrees, it is easy to get sick. Our country generally has low temperatures in winter, so the water temperature must be strictly controlled when raising Luohan fish in winter.

1. When the outside temperature is relatively low, use the heating rod immediately. The heating rod can increase the temperature of the water and raise the water temperature to the suitable temperature for Luohan fish. If Luohan fish is raised indoors, you can turn on the air conditioner or heating and cover it with insulation film.

2. When changing the water, you must also control the water temperature. The temperature of the new water is generally low. Immediately pour it into the fish tank. The strong temperature difference will stimulate the Luohan fish. At this time, it is best to use hot water to blend so that the temperature of the new water is consistent with the temperature of the original tank water.
