Do Betta Fish Like Light? The Advantages Of Aquarium Light For Bettas
Betta fish, like any other fish, do not have the capacity to “like” or “dislike” light in the same way that humans do. However, light is an essential factor in their environment, and it can have a significant impact on their behavior and health.
Bettas, like many other animals, have an internal clock known as the circadian rhythm that helps regulate their sleep and wake cycles. Light is one of the most important environmental cues that helps regulate this internal clock.
In bettas, exposure to light stimulates the production of the hormone melatonin in the brain. Melatonin is known to play a key role in regulating sleep cycle and wake cycle in many animals, including humans. When melatonin levels are high, bettas tend to become drowsy and sleep, while low levels of melatonin are associated with increased wakefulness and activity.
In natural environments, bettas are exposed to changes in light and dark cycles throughout the day and night. In captivity, Betta fish need light to regulate their sleep and wake cycles, as well as support their overall health and wellbeing. Exposure to a consistent and appropriate amount of light helps maintain their circadian rhythm, which is essential for their physical and mental health.
Moreover, light plays a crucial role in the growth of live plants in Betta fish tanks. Plants require light for photosynthesis, the process by which they produce energy and oxygen from carbon dioxide and water. In addition to providing oxygen and removing carbon dioxide from the water, live plants also provide natural shelter and hiding places for bettas, and can help improve water quality.
Which Kind Of Light Do Betta Fish Prefer: Natural Or Artificial Light?
Betta fish are not particularly choosy when it comes to the type of light they prefer, as they can adapt to both natural and artificial light. However, there are some differences between the two that you should be aware of.
Natural light, or sunlight, provides a full spectrum of light that is beneficial for both the growth of plants and the overall health of your betta fish. Sunlight can also provide a more natural and aesthetically pleasing look to your aquarium. However, it’s important to be aware that direct sunlight can cause fluctuations in temperature and can also lead to excessive algae growth.
Artificial light, on the other hand, can provide a more consistent and controlled environment for your betta fish. You can choose the intensity and duration of the light to suit the needs of your aquarium, and you can also use different colors to create a specific aesthetic or to enhance plant growth. One potential drawback of artificial light is that it doesn’t provide the full spectrum of light that sunlight does, so you may need to supplement with other types of lighting if you want to promote plant growth.
Ultimately, the type of light you choose will depend on your personal preferences and the needs of your betta fish and plants. Some aquarium enthusiasts prefer the more natural look and benefits of sunlight, while others opt for the consistency and control of artificial light.
Recommended Lighting For A Betta Tank

Do Betta Fish Need Light At Night?
Betta fish do not need light at night, and in fact, it is recommended that they have a period of darkness. Like all animals, Betta fish require a natural day and night cycle to maintain a healthy and balanced circadian rhythm.
In their natural habitat, Betta fish experience natural light cycles that follow the rise and fall of the sun. This means they receive periods of darkness at night. Providing your Betta fish with a consistent and appropriate light schedule can help regulate their natural biological rhythms and promote a healthy lifestyle.
Excessive light during the night can disrupt their natural circadian rhythm, which can lead to stress and health problems. In the wild, Betta fish are nocturnal and do most of their activities at night, so exposing them to constant light can cause them to become disoriented and stressed.
Can Betta Fish See In The Dark?
Although Betta fish are renowned for their excellent vision, they are diurnal animals and unable to perceive their surroundings in complete darkness. Being diurnal means that Betta fish are active during the day and sleep at night. In the wild, Betta fish follow the natural light cycle and are most active during the day when there is ample light. Betta fish possess specialized photoreceptor cells in their eyes, including both rods and cones, which allow them to detect colors and movement. However, these cells are not as sensitive as those found in nocturnal animals, such as owls or cats.
While Betta fish can navigate through low-light conditions, they cannot see in total darkness. In a dimly lit environment, they may be able to move around, but their vision will not be clear. Therefore, providing Betta fish with an appropriate light schedule that includes a period of darkness is crucial for their overall well-being.
It is essential to understand that Betta fish require light to see their surroundings and maintain their biological functions. Nevertheless, it is also important to acknowledge that excessive light exposure can harm their health, leading to stress and fatigue. By providing an ideal light schedule, Betta fish will thrive, and their natural behaviors will be enhanced. Therefore, ensuring that Betta fish are provided with an appropriate light schedule is crucial for their physical and mental health.
