How do you know when and how often betta fish breed

The omen of betta breeding is obvious. First of all, the abdomen of female fish will become bigger when breeding, and its temper will be abnormally irritable. And their appetite and activity will decrease, and some will hide in the corner without moving. The omen of male fish is even more obvious. When breeding, they will wrap the air inhaled from the water surface with mucus in their mouths and spit it out with their mouths. Bubbles made of mucus can easily be adsorbed together, thus building bubble nests.

1. How to know when betta fish breed

The signs of betta fish breeding are obvious, and breeders can observe them carefully at ordinary times. Under normal circumstances, the belly of the female fish entering the breeding period will become bigger and bulging. They will also become grumpy and often attack fish close to them. Food intake and activity will decrease, and others will hide in the corner without moving.

When male fish want to reproduce, the signs are obvious. They will first use mucus in their mouths to create bubbles. Because of mucus, bubbles are not fragile and can stick together well. After the male fish builds the bubble nest, they will chase each other with the female fish. In the process of chasing, the female fish will discharge their eggs and the male fish will be inseminated forward.

2. How often do betta fish reproduce

Betta fish reproduce frequently, and they can reproduce again 4-5 days after successful hatching of small fish under normal circumstances. They can reproduce more than a dozen times a year, and both the frequency and speed of reproduction are relatively fast. When raising betta fish artificially, it is not recommended to let them produce too frequently. Because frequent production will not only harm the body and shorten the life span, but also affect the quality of offspring. Therefore, it is recommended that they reproduce once a month and not more than four times a year.
