How to choose aquarium light for Betta fish?
Betta fish in a low-tech planted tank
The first thing you should consider is a light that mimics the light/dark cycle of the sun, which has a huge impact on the circadian rhythm and sleeping habits of your fish. Most aquarium light products with timers can be programmed so that the intensity and color of the light adjust automatically to mimic the pattern of the sun.
If you are keeping your Betta fish in a planted tank, your main aim should be to find an aquarium plant light that will first and foremost promote the health of your aquarium plants.
How bright your light should be will largely depend on the size of your tank, and whether you have a planted tank or not. Plants like Anubias, ferns, and crypts don’t require high-intensity lighting. On the other hand, you should get medium to high-intensity lighting if you keep stem plants and demanding carpeting plants.
Bettas are not very picky when it comes to aquarium lighting. If you have lighting that can keep your plants happy, it should be enough for your Betta fish too. That said, there is no point in getting a too-bright light when you have a bare tank with only one Betta fish.
The size and shape of your fish tank is another factor you should consider. If you’re keeping your Betta in a specially-shaped tank or bowl, then you should stay away from a mounting fixture and opt for a lamp with a stand instead.
How large your aquarium is will also determine what type of light you should get for your Betta fish. There are aquarium lights designed only for tanks 5 gallons and below, and there are models that can accommodate aquariums as large as 60 gallons.

What is the best light schedule for Betta fish?
Betta fish hides under aquarium plants
Bettas hail from tropical Asian regions, which means they receive a good amount of sunlight every day. Even in rainy seasons, regions where you will find these beautiful fish get an average of 10-12 hours of sunlight.
When keeping Bettas as pets, you would want to provide them with this amount of light too. They can do well between 8 and 12 hours of light. Give them more than that, and they may become overly stimulated and may weaken due to stress.
A good way to keep your Bettas happy and healthy is to either add plants or decorations inside the tank that will help mimic their natural habitat. This way, even if you choose to keep the lights on for 12 hours for high-maintenance plants, your Bettas will be okay as they have enough shade and places to hide, away from direct light.
As for the lighting schedule, it’s good to mimic sunrise and sunset times. This shouldn’t be a problem since most aquarium lights today come with such a feature.
Frequently Asked Questions
Do Betta fish need a light?
Bettas do need aquarium light. Not only does it help their beautiful colors to pop, but it also helps them maintain a regular day/night cycle. Most aquarium lights today can mimic how the sun’s intensity changes throughout the day. This will help your Betta follow a schedule where they can be active during the day and rest or sleep at night.
Should I turn my Betta fish tank light off at night?
You should. Bettas only need between 8 and 12 hours of light. Once you turn off the light at night, you will notice them become less active. That is because, like other fish, Bettas do sleep and will benefit from the dark to be able to rest well.
Do Betta fish need darkness to sleep?
Not necessarily. Bettas have unique personalities. You will find some to be hyperactive while others tend to be shy and less energetic. Even healthy Bettas would spend a few minutes during the day to lay on a leaf or hide behind an aquarium decor or hardscape to rest or take a nap. However, as mentioned, they do benefit from the darkness and will be able to sleep properly when the lights are turned off.
Does too bright a light stress Betta fish?
Too much brightness is not good for Betta fish, just as it is not good for any type of fish or animal for that matter. When the aquarium light is too bright, it can cause an excessive algae breakout, harmful to both fish and plants.
Too bright a light can also overstimulate them. When they become too active due to constant bright light, they won’t be able to get enough rest, especially when there aren’t a lot of hiding places inside the tank. It could then stress them out and make them less immune to illness. Not to mention that some Bettas can be shy and will not come out if the aquarium light is too bright.
