1. Density: Arhat fry are not very big, but they grow rapidly and have a high demand for oxygen. When breeding artificially, it is necessary to control the breeding density and not let them suffer from hypoxia.

2. Water temperature: Arhat fry is just born, which is not suitable for the external environment. It is best for breeders to raise the water temperature to above 30 ℃. In the high temperature environment, their appetite and activity are the highest, and their growth speed will be accelerated.

3. Water quality: Siraitia grosvenorii does not require very high water quality, and they can live in neutral or weakly alkaline water. Breeders only need to keep the PH value between 6.5 and 7.2. Usually, it takes 3-5 days to change water, and the amount of water change each time is controlled at one third of the total water volume.

4. Feeding: Lohan fry can not eat much food, so breeders can choose some simple and digestible food to feed them. When feeding, we should ensure the diversity of food and avoid the situation of single feeding habits.

If arhats fry grow fast, they should be fed more nutritious food. Such as small fish, shrimp, loach, red worm, Tenebrio molitor, bread worm, lean meat, animal viscera and so on. Arhat fry have a great demand for food, so breeders need to feed them 3-4 times a day, and the amount of each feed can be eaten within 5 minutes.
