Fertilized eggs need to be attached to the fish nest to hatch, so the breeding tank should be put into golden grass or brown silk handle, can also be laid at the bottom of the box. The water quality should be acidic, the concentration of hydrogen ion is 158.5 μ mol / L ~ 251.2 μ mol / L (pH value 5.6 ~ 6.8), the water temperature is 25 ℃ ~ 26 ℃, and the fish tank is placed in the place without strong light.

How to choose to kiss eel
If we want to choose the seedlings with more eggs, high fertilization rate, emergence rate and good quality, we must choose the rice field eel with a certain age, weight, strong physique, no serious disease and trauma as the parent eel. In the non-breeding season, it is difficult to distinguish between female and male eel in appearance, and usually stay on the basis of body length. Most of the ricefield eels are female when their body length is 20 cm-35 cm, and most of them are male when their body length is more than 45 cm. Under normal circumstances, you can choose to stay at 3:1 according to the above two body length groups.
