Betta fish, also known as Siamese fighting fish or Betta splendens, is a popular freshwater tropical fish. It belongs to the larger family of Characidae and is native to Southeast Asia.
Betta fish like light. Bettas are tropical fish, so they prefer brighter environments. A well-lit aquarium will give your betta the perfect environment to swim and breed. However, you should still know the limitations of providing light for your betta fish’s survival and long lifespan.
While many betta fish enjoy being in a brightly lit area, there are some that don’t do well in bright light. If you have a fish that seems to shy away from light, try adding some plants or artificial objects near its aquarium to create shade and offer it a refuge.

Why Is Light Important for Betta Fish?
The purpose of light for fish is generally to provide an environment in which they can grow and thrive. Bettas are tropical fish, so they need bright environments to survive. The combination of natural lighting and traditional aquarium fixtures creates the perfect environment for betta fish growth and reproduction.
Low light levels can make it difficult for the fish to see and swim, making them quite unhappy. Providing enough light for your betta is important not just because it will make them happy, but also because they need sunlight to grow healthy. A properly lit tank provides your Betta with the appropriate amount of Vitamin D, which is important for his physical health.
Do Betta Fish Like Sunlight?
Yes, betta fish do like sunlight. However, they should not be kept in direct sunlight for long periods of time or their skin will become burned. When kept in an aquarium with other fish that get plenty of natural light, a betta can live quite comfortably without any supplemental lighting at all.
Betta fish are tropical fish and as such, they do best in environments with lots of light. However, not all betta fish like bright lights. Some bettas prefer shadier areas or those that shy away from direct sunlight may benefit from having less light in their tank. If you have a betta fish who doesn’t seem to enjoy the brightness of your tank try adding aquarium decorations such as plants or wood to create shade and offer your fish cover from the light.
In addition, a betta fish that is kept in a tank with plenty of natural light will not be bothered by the lack of sunlight. It will not become stressed or ill, and it will remain healthy and happy.
Do Betta Fish Like Light at Night?
Most betta fish will be active during the day, but some may choose to sleep during the night. If your betta fish sleeps during the day, you can keep a light on at night to stimulate their activity. However, do not leave a light on all night long – this will become too bright and stress your betta out. Instead, turn off the light partway through the evening and let them begin their sleeping hours. If your betta fish sleeps peacefully during the night, it will be easier to make them active during the day by turning on a light in the morning. Just be sure to turn off the light at night so that your betta can get some rest!
Do Betta Fish Like Light Bulbs?
Yes, betta fish like light bulbs. They are actually quite adaptable to different types of lighting as long as it is not too bright or too dim. Bettas can even thrive in a completely dark environment if they have access to a few bright light sources.
A general rule is that the higher the wattage of the bulb, the brighter your fish will like their environment.
How Many Watts of Light Do Betta Fish Need?
Betta fish generally need around 1.5 to 4 watts of light per gallon. This means that a 20-watt bulb will be enough for most betta fish tanks. However, if your tank is larger or has an extended reach from the light source, you may want to consider using a higher wattage bulb.
In addition, if you are using a fluorescent bulb, the higher the wattage of the bulb, the better. Fluorescent bulbs produce a whiter light than incandescent bulbs and will help your betta fish to thrive.
How Long Should Betta Fish Get Light?
Betta fish need light for around 8-12 hours a day. However, the length of time that they need light depends on their activity level. Bettas that are active during the day will require more light than those who are less active. At night, betta fish can handle darkness for 12-16 hours as they will most likely sleep. However, they will enjoy access to live plants or a few bright light sources in their tank so that they have something to look at during the night if they are still active.
What Are the Impacts of Too Much Light?
Betta fish need a certain amount of light in order for them to live and reproduce and too much light can be harmful to them. As mentioned earlier, they need around 1.5 to 4 watts of light per gallon, and over-lighting a tank can cause your fish to become stressed and unhealthy. In addition, too much light will also make it difficult for your fish to see their food and tend to encourage territorial behavior in the tank. Continuous exposure to too much light will stress your betta out and may even cause them to die.
How Can I Reduce the Amount of Light My Betta Fish Get?
There are a few ways that you can reduce the amount of light your betta fish receive. One way is to use a lower wattage bulb or simply turn off the light when you are not using it. You can also install dimmer switches in areas where there is a high amount of light, such as near the tank’s surface. Finally, adding a few bright light sources, such as an LED bulb or a full-spectrum fluorescent light will help to enrich your fish’s environment and ensure that they receive the appropriate amount of light.
What Are the Impacts of Insufficient Light?
If your tank doesn’t receive enough light, your betta fish will start to exhibit signs of darkness such as sluggishness and spawn prematurely. They may also start to eat their own scales or swim around in circles obsessively. Lack of light can also lead to the growth of algae and other types of plant life that are not good for your fish. In addition, your betta fish may become lethargic, infertile, may experience stunted growth, and maybe uninterested in eating.
How Do I Increase the Lighting for My Betta Fish?
The best way to increase the lighting for your betta fish is to add more light sources or fixtures in their tank. You can also add a second light fixture if you have one already. You can find fluorescent fixtures at most pet stores or online. Some options include compact fluorescents (CFLs) or tubes that can be placed under the water. HPS bulbs are also available and are a good choice for larger tanks. They emit more light than traditional lamps, but they do require electricity to operate. Finally, you can add an LED fixture to your tank if you have the space. These lamps produce a consistent level of light and don’t use any electricity at all.
