Betta fish are known for their long, flowing fins and vibrant colors, but did you know that there are differences between male and female bettas? For starters, female bettas tend to be smaller than their male counterparts and have shorter fins. They also lack the bright colors and patterns that males are known for.

Despite these differences, female bettas are just as beautiful as males and make great additions to any aquarium. If you’re thinking about adding a betta to your home, be sure to research both sexes to see which one is right for you.

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

Male bettas will have a more pointed belly, while female bettas will have a rounder belly.
