There are several reasons why chicken hearts do not eat.

1. The environment changes suddenly. If the environment suddenly changes, the fish will not be able to adapt to it for a while, and they will not like to eat. They maintain a good and stable water quality and eat after a period of adaptation. For example, long-distance transportation, sudden cylinder change.

2. Water temperature and water quality. The water temperature is too high or too low. If the water quality is too old or too new, although it does not necessarily affect the life of the fish, it definitely affects the appetite of the fish. The solution is to adjust the water temperature and water quality as required to achieve a certain standard.
