Why do male and female betta fish fight in the same tank?
I'm curious about something. Why do male and female betta fish fight in the same tank?
That's a great question! Betta fish are known for their aggression towards other fish and even their own kind. Male bettas in particular can be very territorial and will fight other males, females or even their reflections. When you put a male and female betta fish in the same tank, it can trigger their instincts to mate, but it can also cause aggression and fighting.
