The Betta Light Requirements: How to Choose the Right Betta Light for Your Tank

Betta fish need at least two sources of natural light to thrive. This is because Bettas are nocturnal, or active during the night when it’s dark. They spend their days hiding in hiding places or floating on the top of your tank so they can see what’s going on below. Bettas do not have the ability to see color like us humans and therefore need a source of white light to stimulate their secondary (or third) eyes so they can see color. In order for your black betta fish for sale to be healthy, it needs two sources of light: one that lights up its tank so you can see it at night and another that illuminates its tank during the day so it can hide in dark places during the day.
