Courtship Habits of Betta Fish

During the reproductive period of betta fish, the male fish is very colorful and has a process of courtship and nest building. Before spawning, the male fish first chooses a place with calm water and shelter from the wind. It sucks air from the mouth and spits out mucus to form small bubbles. Countless small bubbles stick together to form a floating nest with a raised or slightly flat surface.

When the nest is built, the male fish begins to propose to the female fish. The beautiful male fish keeps swimming around the female fish, spreading his beautiful fins as much as possible, opening his mouth wide, and protruding gill membranes. Bright red gills can be seen inside the gill membrane. During the courtship process, the body color becomes particularly vivid, and the body and fins appear iridescent. The male fish trembles with extreme excitement. If the female does not respond to the male's advances, the male will become angry and chase the female until she is forced to jump out of the water and escape. After a complicated courtship, the female accepts the male's advances, approaches the male, and then suddenly lies down on her side. The male immediately clings to the female and turns the female's body upside down so that her belly is facing up. , the male fish sticks to the bottom of the female fish. At this time, the male and female fish each release eggs and sperm. Since the eggs are heavier than water, the eggs sink in the water. At this time, the male fish waiting below catches them with his mouth, coats the eggs with a layer of mucus, and then swims upward to stick the eggs under the floating nest.
