Can Male and Female Betta Fish Live Together?
Male and female Betta fish can be kept together, although they are known for their strong territorial nature. However, most of the fighting typically occurs between male Betta fish. If you have one male and one female, fighting usually won’t happen. However, when keeping Betta fish together, it’s important to provide them with plenty of space to reduce the chances of fighting. Additionally, if the male Betta fish enters the breeding period and the female does not have eggs, the female should be removed to prevent the male from continuously chasing her, which could lead to injury.
