Do Betta Fish Need Light?

A prevalent question among Betta owners is whether or not a light is necessary for the needs of their Betta fish. The obvious answer is – “Yes”. Without a doubt some sort of lighting is necessary for the health and well-being of your Betta fish. Light signals to the fish when it’s morning, noon, and night. Keeping your Betta bowl or tank close to a window is just not enough for those people living in temperate climates. Remember that Bettas are tropical fish that live close to the equator where the sun shines every day and where there is no winter.

Betta’s Biological Clock

Betta fish just like humans have a biological clock and prefer a stable sleep schedule. In the wild they normally sleep as soon as night sets in and wake up right before sunrise. But since Bettas are kept indoors their natural sleep cycles can become easily disrupted. Any interruptions will cause physical stress to the fish which leads to a comprised immune system and later disease. Having an aquarium light providing adequate lighting for your Betta’s bowl or tank is the best investment in your fish’s health. In addition, equipping the light with an automatic timer will ensure uninterrupted and quality sleep patterns for your fish. (dt/ba)
