When pairing Betta fish, it is important to keep them in separate tanks or divided tanks to prevent aggression and fighting. Male Betta fish should never be housed together, as they are territorial and will likely fight. If you want to pair a male and female Betta for breeding purposes, it is best to introduce them in a controlled environment and monitor their behavior closely. It is important to provide plenty of hiding spots and plants to create separate territories within the tank. **
