1. The water temperature is constant: Betta fish has just hatched and has poor adaptability to the environment. It is best for breeders to keep the water temperature in which they live between 26-27 ℃ and minimize the temperature difference. If conditions permit, it is recommended to install a heating rod, so as to avoid the death of betta fish caused by temperature difference.

2. Clean water quality: Betta fish does not have strict requirements on water quality, but newly hatched betta fish need clean and refreshing water to grow better. Breeders need to ensure that the water quality they live in is clean, and try not to change the water one week before the hatching of betta fish, so as to avoid too much fluctuation of water quality affecting their growth and development.

3. Static water flow: Betta fish don't like to live in a fast-flowing environment, especially newly hatched small fish, which can't adapt to the fast-flowing water flow, so it is best for breeders to keep the water environment where they live still. Usually, the use of filters should be reduced, and the power of oxygen pumps can also be reduced.

1. Food selection: The newly hatched betta does not need to be fed for the first 3 days. After 3 days, the breeder can feed them some paramecium, shrimp eggs in good years, cooked egg yolk, green algae powder and other foods.

2. Feeding frequency: Newly hatched betta fish need to be fed a small amount of times, preferably 3-4 times a day, and the amount of each feeding can be eaten within 3 minutes.

3. Feeding method: Because betta fish has just hatched successfully, its swimming ability is not strong. When feeding, it is best for breeders to keep food close to them, which is more beneficial for them to eat.
