1. The lowest temperature of grass goldfish grass goldfish can grow in water temperature above 0 ℃, because they are cold water fish, and the acceptable temperature range is relatively wide. As long as the water temperature in which they are raised is kept above 0 ℃, they can survive. Although they can survive in low temperature environment, it is best for breeders not to grow them in low temperature environment for a long time. Because the water temperature is too low, their appetite and activity will be affected, and even if they can survive, their growth status will also be affected. Under normal feeding conditions, it is best to install a heating rod to keep the water temperature in a stable range.
2. Cultivation method of grass goldfish1. Fish tank: grass goldfish is too large, and its body length is 30 cm after adulthood. Breeders need to prepare a larger fish tank for them, so as to ensure that they have enough living space.
2. Water temperature: Grass goldfish does not require high water temperature, and breeders can keep the water temperature in a stable range. If conditions permit, it is best to install a heating rod to keep the water temperature between 18-25 ℃.
3. Water quality: Grass goldfish can grow in weak acid, weak base and neutral water. When rearing artificially, they can grow well as long as the water quality is kept clean. When changing water at ordinary times, we should pay attention to the temperature difference between new water and old water, and pay attention to the fact that the amount of water should not be too large, and it can be controlled at one third of the total amount of water.
3. Feeding: Grass goldfish can eat more food, and breeders can choose to feed with animal feed and plant feed. This can not only ensure that they have enough food, but also ensure balanced nutrition.
