How do I know if my female betta is happy?

You know your female betta is happy if she is energetic and active, especially during mealtimes and play sessions. And while a female betta looks plainer than its male counterpart, if she is happy, her colors will be vibrant and not faded. A happy female betta is usually responsive to a male’s mating efforts as well.

If your betta has a poor appetite, looks tired, or constantly hides from you, she may be unhappy or sick. She needs a lot of stimuli and enrichment to stay happy. Give her a clean tank, a nutritious diet, and a variety of toys to make her happy.
