How do you tell if your betta fish is a girl or boy?

1. Look at the body shape. Male betta fish have longer, more streamlined bodies, while female betta fish have shorter, rounder bodies.

2. Look at the fins. Male betta fish have longer, more elaborate fins than female betta fish. The fins of male betta fish are also often brighter in color.

3. Look at the egg spot. Female betta fish have a small, white egg spot on their bellies. Male betta fish do not have an egg spot.

4. Observe the behavior. Male betta fish are more aggressive and territorial than female betta fish. Male betta fish will often flare their fins and charge at each other. Female betta fish are more peaceful and will usually avoid conflict.

If you are still not sure if your betta fish is a girl or boy, you can take it to a pet store or veterinarian for identification.
