However, this does not mean that they do not like light. In fact, bettas love to swim in well-lit areas and often congregate near the water’s surface, where the light is the brightest.

As we already know, Bettas like natural white light. Therefore, white light is usually used as an accent color in aquariums as it helps make your Betta’s colors appear more vibrant.

However, some aquarists keep blue or red lights on in their betta tank at night. Does that bother Betta fish? Keeping colored lights on in the daytime may not bother bettas; however, at night definitely disturb them.

What Happens If Your Betta Gets Too Much (Or Too Little) Light?

Now that we know what type of light is best for Bettas, let’s discuss the effects of too much or too little light.

Too Little Lights

  • If your Betta does not get enough light, it can result in them becoming lethargic and depressed. That may force them to lay at the bottom and lose interest in exploring the tank.
  • If betta fish don’t get enough light, they may lose their vibrant color. Instead, they may look dull and weak. However, betta fish may become pale for other reasons, including pH fluctuation, algae bloom, cold water, etc.

Too Much Light

  • Overstimulation may occur when your Betta is exposed to excessive light. Your Betta will be hyperactive if it doesn’t know when to relax. They need to rest for their body to function properly! Otherwise, they may get agitated and stressed as a consequence of this.
  • Overexposure may lead to other problems as Betta may stop eating. This can happen for stress; however, it can also occur if bettas find it hard to understand the feeding time.

In extreme cases, Bettas may die if they do not get enough light or are exposed to too much light. So, to sum it up, it is crucial to find a balance when it comes to lighting for your betta fish. Of course, they need some light, but too much or too little can be harmful.

The best way to determine how much light your betta needs is to observe their behavior. If they are swimming near the water’s surface and seem to be enjoying the light, they are getting the right amount.

Some people may think that Bettas need direct sunlight in order to thrive. However, that’s not the case! In fact, too much direct sunlight can actually be harmful to your Betta.

  • The water in the tank can overheat quickly if placed in direct sunlight, which can be very dangerous for your fish.
  • In addition, the sunlight can also cause algae to grow in the tank. Bettas do not like being in tanks with a lot of algae, so it’s best to avoid direct sunlight.

If you want to place your betta tank in a sunny spot, make sure to use a tank cover to filter the sunlight.

Use An Artificial Light

LED lights: Led lights are becoming increasingly popular in aquariums because they are energy efficient and last a long time. They also emit very little heat, so you don’t have to worry about the water in your tank getting too hot.

There are many different types of LED lights available on the market, so you can choose the one that best fits your needs.

Incandescent bulbs: Incandescent bulbs are not recommended because they are not very energy efficient. They also emit a lot of heat, so you’ll need to be careful about using them in your betta tank.

Fluorescent bulbs: Fluorescent bulbs are a good option for lighting your betta tank. It’s the second best choice after LEDs.

Use A Timed Light

Use a timer to turn on and off the light. With this setup, you can be certain that your Betta is getting the proper amount of light. Since Betta fish need 8 to 12 hours of light each day, you’ll want to adjust the timer to account for this requirement.

You can use a separate timer to connect with your aquarium light. On the other hand, you can buy an aquarium light with a built-in timer. Some aquarium light even has the 24/7 functionality to mimick the day & night in an automatic cycle.

Hence powerful lighting is unnecessary in most cases. After installing the light watch your Betta behavior. If you notice your Betta flaring up, the light probably reflects too much. It turns the aquarium glass into the mirror for Betta. That’s making him think about rivals in the tank.
