Do fighting fish spit bubbles before courtship?

Generally, male betta fishes are in estrus from March to June, 10. During this period, the male betta will keep spitting bubbles until the female betta is pregnant with eggs, and will stop spitting bubbles for mating.

During the breeding period of fighting fish, the males are very colorful and have a set of processes of proposing marriage and nesting. Before laying eggs, the male fish first chooses a calm and sheltered place on the water surface, and sucks air and spits mucus through his mouth to form bubbles. Numerous bubbles stick together to form a floating nest with a raised or slightly flat surface. When the nest was built, the male fish began to propose to the female fish. The beautiful male fish swims around the female fish, with beautiful fins open, mouth wide open, gill membrane protruding, and bright red gills can be seen in the gill membrane. In the process of courtship, the body color becomes particularly bright, and the body and fins appear iridescent. The male fish trembled with excitement. If the female fish does not respond to the male fish's courtship, the male fish will become angry and chase the female fish until it is forced to jump out of the water and escape. After complicated courtship, the female fish accepted the courtship of the male fish, approached the male fish, and then suddenly lay down. The male fish immediately clings to the female fish, turns the female fish over and lets the male fish get stuck under the female fish. At this time, the male fish and the female fish excrete eggs and sperm respectively.
