Can betta fish aquariums have lights?

Betta fish aquariums can have lights. In fact, lighting is important for the well-being of betta fish. Bettas are tropical fish that require a water temperature of between 75 and 82 degrees Fahrenheit, and lighting is necessary to heat the water. Additionally, lighting is important for regulating the betta's sleep cycle and stimulating food-searching behavior. However, it is important to choose the right type of lighting for a betta fish aquarium. Bettas are sensitive to bright lights, so it is best to use a dim light that won't stress the fish. It is also important to provide the betta with hiding places where it can retreat if it needs to get away from the light.
