It takes about half a month for female cichlids in Sanhu to hatch and spit out their own small fish. During the incubation period, special attention should be paid to protecting parent fish and providing them with a safe, stable and comfortable environment for hatching fish eggs. Don't change the environment suddenly, so as not to frighten the mother fish and lead to egg abandonment or swallowing. If you have some experience, you can dig the eggs out of the mother fish's mouth and raise them separately after the mother fish contains eggs.
