The breeding period of betta fish usually lasts for nine days. The breeding process includes steps such as setting up the environment, selecting fish, removing the female fish, and removing the male fish. The whole process takes about nine days.
Specific Steps and Environmental Requirements for Breeding
Environment Setup: The breeding tank requires simple filtering equipment, like a sponge filter. Turn off the filtering system during the breeding period and turn it on again when it's time to feed later. Place floating leaves in the tank for the male fish to build nests, and also place aquatic plants for the female fish to hide.
Selecting Fish: Choose healthy male and female fish and observe whether they are willing to pair up. If the female fish is willing to swim under the male fish's nest, it means the pairing is successful.
Removing the Female Fish: On the second day, if the female fish swims away and the male fish stays at the nest, it indicates that the eggs have been laid and fertilized. At this time, remove the female fish, and the male fish will protect the baby fish without eating or drinking.
Removing the Male Fish: Three to four days later, the baby fish hatch. The male fish will continue to take care of the baby fish for another two to three days until they learn to swim and start to eat.
Breeding Characteristics of Different Kinds of Betta Fish
Siamese Fighting Fish: Siamese fighting fish are easy to raise and breed. The number of eggs laid usually ranges from 50 to 500. The fertilized eggs can hatch into fry two days after being fertilized.
Fantail Betta Fish: A pair of parent fish can lay 200 fertilized eggs each time, which will hatch in about 36 hours. The fry can swim freely three days after hatching.
Chinese Betta Fish: The breeding season is from April to August, and it is more common in May and June. Under suitable water temperature conditions, they can also breed throughout the year.
