Do Betta Fish Need Light?
A betta fish needs light. In fact, it needs plenty of it. But it only requires light during the daytime. A betta likes to sleep in a pitch-black dark area.
Bettas are very similar to humans. It needs to sleep in darkness, and it needs light during the daytime. So, the answer to your question is, a betta needs light, but only during the daytime. The lights should be turned off when it is sleeping.
If you are keeping your betta in a fish tank, then you should allow it to sleep in complete darkness so it can rest properly.
Why Do Bettas Need Light?
The reason bettas need light is that their sleeping cycle is very similar to ours. A healthy betta requires 8-12 hours of light and 12-16 hours of darkness for it to rest.
In the wild, a betta lives in the shaded area of the water. It never lives directly under the sun. This is why it does not require sunlight to survive properly.
However, due to living this way in the wild, bettas are used to waking up in the morning and going to sleep when the sun goes down and the area is completely dark.
So, if you can’t recreate this for your betta at home, your betta will most likely suffer.
What Kind Of Lights Should You Use For Your Betta?
The great thing about bettas is that it does not require sunlight to survive. As I have mentioned in the previous paragraph, a betta needs lighting to maintain a regular routine just like it does in the wild.
If you are keeping your betta in a fish tank, or an aquarium, using artificial lights will do. You can set lights in the tank and control it according to your betta’s needs.
You should use regular artificial lighting for your betta.
A lot of the time people opt for LED lights for their betta. The reason behind this is due to different lights, the coloring of your betta looks more gorgeous and majestic to the eyes.
The thing about using LED lights is that bettas can see color just like us. In fact, their eyes are very similar to ours. There are no scientifically proven studies that show, LED lights can irritate your betta.
If you are using blue lights to enhance the hues of your betta, then do not leave it on. you can keep the blue light on for an hour and then turn it off again.
A lot of the time, people ask whether they can leave the blue light on in the fish tank at night. The answer is, no. You cannot do that. I have said this over and over, a betta likes to sleep in darkness. Leaving the blue light on will irritate the betta and disrupt its sleep.
However, using regular lights is better because it is safer. And when it comes to pets, better be safe than sorry!
How To Find The Best Lighting For Your Betta?
While lighting is important for your betta, you can also overwhelm it by providing too much light for it. In simpler words, your usage of artificial lights might be too much and it might become too bright for the betta to handle.
You do not need a very powerful and bright light for your fish tank. The proper measurement of light for LED lights is 1 watt per gallon. It can be below 1 watt per gallon as well but it should not cross the 1-watt limit.
For fluorescent lights, you should not go over 3 watts per gallon.
Things To Be Careful Of When You Are Using Artificial Lighting For Your Betta
As much as we have been emphasizing on the importance of darkness and light in a betta’s life, there are things you should be cautious of. You can’t just set up lights on your fish tank and forget about it. Here are some things you need to be careful about:
- Due to the usage of artificial lights in the tank, the light might reflect on the sides of the tank. Your betta will most likely notice it. This is a very common phenomenon amongst pets where they see their own reflection and think of it as a threat.
If your betta is starting to act aggressively after turning on the lights in the tank, then it is taking its own reflection as a threat.
If your betta is living alone in the tank, then it might act more aggressive and erratic.
Here is how you can solve this problem:
- This problem can be solved quite easily. When you are turning on the lights of the tank, be sure to turn on the lights of your room or the room the tank is in, as well.
- Introducing your betta to the light slowly, and getting it used to the lights is a great idea as well. However, this might seem very complicated to some people.
- You can try to darken the outer area of the tank by using paper.
If all these remedies do not work, then you should go back to the pet store and find a weaker and softer light.
Why Should You Use Artificial Lights Instead Of Sunlight For Your Betta?
I have been saying that bettas do not require sunlight to survive at all. I have also recommended using artificial lights over leaving the tank in sunlight.
This might make you wonder why you should do that. You can think of it as extra spending. However, leaving the tank in sunlight is not safe for your betta at all. Here is why;
- Leaving the tank in sunlight may cause algae blooming in the tank. This will cause the water to get dirtier often and reduce the visibility inside as well. But this does not stop there.
- With more production of algae in the water, there will be more bacteria trapped in the water. This will physically hurt your betta by causing various diseases.
- Leaving the tank in sunlight will cause the temperature in the water to go up rapidly. With warmer water, your betta will feel more uncomfortable and will become very stressed.
The solution to all these problems? Use artificial lights for your betta. You will be able to control when to give your betta rest by providing it darkness and when to give it light.
What Can Go Wrong If Your Betta Gets Too Much Light?
A lighting routine is an absolute necessity for a betta. Without a proper lighting routine, a betta’s natural living cycle will be disrupted.
As a betta is a tropical fish, it has a very similar sleeping routine as us, humans. This means, your betta will not be able to sleep with the lights on, just like you.
When you will be unable to provide your betta with the darkness it requires, here is what can go wrong.

- Without proper sleep, your betta will be very stressed. It will start to act very jumpily, nervous, and will swim around very erratically in weird motions and directions.
- With their sleep cycles getting disrupted, a betta will slowly start to lose its vigor and strength. It will most likely start lying down at the bottom of the tank at odd hours.
- As a human, you will agree that when you do not get proper sleep, you do not feel good. Now, bettas are very similar to humans. Without proper sleep, your betta too, will not feel great. It will not live happily at all.
- Without proper sleep, a stressed betta can start jumping around. Bettas can jump quite high as in the wild, this is how it transports from one place to another. Your betta might start jumping out of the tank.
Now, this might not sound bad, but a betta is a fish. A fish cannot survive without water. If your stressed betta spends 10 minutes out of the water, it will die.
So, without a lighting routine, you might end up killing your betta. Now you understand, why a lighting routine is essential for your betta.
