It defines the hues and unique beauty of the betta fish precisely and provides an excellent aesthetic to the background.

However, even though betta fish feel great being in the blue spotlight, they will still require you to turn the light off when it is their bedtime. They need to rest and relax to be in good health.

Go for a light with a switch-in timer to make your life easier. As long as you set the timer, it will switch on and off per your settings.

Choosing and Using Blue Light in a Betta Tank 

Once you opt for an artificial blue light system for your betta tank, be consistent with the cycle. Keep the lights on during the day, and turn them off at night.

Most lighting systems these days are equipped to provide the fish with light and nutrients like required vitamins. You will also have zero worries about algae growth in the tank.

If the artificial lighting option bothers you, you can always switch to natural lighting. However, never exposing the fish to direct sunlight would be best. The heat from the sunlight rapidly increases the fish’s temperature levels and leads to death.

If you consider natural light, please place your betta tank with enough sunlight during the day. But not direct sunlight. More the dimness, much the better.

Nevertheless, there is a potential risk of using natural sunlight. Natural light can easily heat the tank and make an ideal environment for algae growth.

Algae in betta tanks are a pain in the neck for you and the fish. It can be harmful to the health of the fish.

So when choosing the right light and color for your betta fish, please consider all the factors and opt for an option that will keep the fish safe and work conveniently for you.
