1, reason: betta spits foam may be due to lack of oxygen. There are many reasons for hypoxia, such as low feeding density, poor water quality or low air pressure caused by weather. Betta fish swim to the surface to breathe when they lack oxygen, because they belong to the climbing perch family, and their auxiliary respiratory organs can directly breathe oxygen on the surface. When breathing on the surface of the water, the exchange of gases with the surface of the water will produce foam.
2. Solution: The breeder needs to change the water in time to ensure that the water in the fish tank is clean. And timely oxygenation to ensure that the dissolved oxygen in the fish tank is sufficient. Later, water should be changed regularly to avoid the reduction of dissolved oxygen caused by poor water quality. Filtration systems or oxygen pumps can be installed if conditions permit, which can effectively avoid hypoxia.
1. Reason: The betta spits out a lot of bubbles, which may be about to breed. The male betta will spit out a lot of bubbles before breeding. These bubbles can prevent other fish from eating the eggs, and also have a certain protective effect.
2. Solution: The breeder needs to give them a separate container. The water temperature should be 1-2 ℃ higher than the original tank. Put aquatic plants or spawning tubes in the container. After waiting for the betta to spawn, fish out the female fish. The male fish can be left in the tank, because the male fish will protect the eggs.
