Look at the fish's fins and tails. A male betta’s fins are long and flow beautifully in the water. Their fins can grow to be quite large, as this is what they use to fend off unwanted fish. They “flare” when they see another male fish, even if it is their reflection in a mirror. Male bettas are famous for this defensive posture.
Female bettas will have shorter fins and tails than male bettas. Most females are less vibrant than their male counterparts.

Observe their behavior. Male bettas are more aggressive than females and do not enjoy the company of many other types of fish.
Females have more personality and are spunkier than males. They can move around quicker than males because of their shorter fins. Females can also live with other females, but males must be kept alone.

Tips & Warnings
If you want to keep multiple bettas in a tank, one male with a few females is the way to go. Give the females plenty of hiding spaces in the tank, as they generally establish a pecking order in the tank.
Buy your betta from a pet store you know to be reputable. Ensure they keep their tanks clean and their fish healthy by visiting the store a few times before making a purchase.
Do not keep more than one male betta in a tank. If two males are in the same tank, they will fight until one dies.
