in groups? Different species of bettas have different personalities. Like Chinese bettas, they are not particularly fond of fighting. As long as the feeding density is well controlled, they can generally be raised in groups. Although Chinese betta can be raised in groups, the number of groups should be controlled at more than 10, because if the number is too small, it is easy to fight with each other.
Thai bettas are not recommended to be raised in groups, because Thai bettas are very aggressive, especially during the breeding season, the fighting between males will be extremely fierce, so Thai bettas are not recommended to be raised in groups. If breeders want to breed Thai bettas, they can install transparent partitions in the tank to allow the male and female fish to adapt first, and then remove the partitions after they are fully adapted, so that they can breed.
? Bettas can be polycultured. They are irascible. Breeders should choose mild fish to be polycultured together. But gentle personality is far from enough, but also choose some flexible fish to mix together, so that the fighting fish is difficult to attack them, but also can reduce the frequency of fighting. You can also choose some benthic fish polyculture, these fish generally live in the bottom, and the area of fighting fish activities is different, in general, there will be no conflict.
