Can you place both a male and female beta in one tank?

Yes, you can place both a male and female beta in one tank, but it's generally not recommended due to aggressive behavior exhibited by male bettas. Male bettas are territorial and may attack females, especially if they feel threatened or if there are breeding conditions present. If you decide to house them together, ensure the tank is spacious and has plenty of hiding spots to reduce stress and aggression. Always monitor their behavior closely for any signs of conflict.
