? Bettas give birth to small fish, but they reproduce by laying eggs, so they don't give birth to small fish directly. When they breed, the male and female pair up and become entwined, with the male squeezing the female with his fins to spawn. After the female fish lays eggs, the male fish will go to inseminate immediately, and the betta fish can lay more than ten eggs at a time. After fertilization, the
male fish will put the eggs into the nest one by one. During the incubation of the eggs, the male fish will always guard by the side and use its fins to fan the water flow to ensure that the oxygen in the nest is sufficient. After 1-2 days, the eggs will hatch into small fish, but at this time the small fish will not swim, the male fish will still guard the side, and will regularly repair the nest to prevent the small fish from falling out of the nest.
2. Water quality: The newly born fry does not need to change the water within 15 days. When the fry is 15-20 days old, the water can be changed once, but the amount of water does not need to be too much. It can be controlled at a quarter of the total amount of water.
3. Feeding: Small betta can be fed with paramecium. After 2-3 days, they can be fed with shrimp. After about 10 days, they can be fed with some cut red worms or mealworms. After a month or so, it can be fed like a big fish.
