The red-bellied phoenix fish can breed, pay attention to the breeding water temperature and the feeding water temperature are basically the same, to ensure sufficient oxygen, and some aquatic plants can be planted in the tank for the fish to breed.

The female fish lays 60~80 eggs each time. The fertilized eggs hatch after 60 hours, and after 80 hours, they can be fed to brine shrimp or water fleas. There is no need to fish out the small fish, because the big red-bellied phoenix fish will take care of the growth of the small fish.
