Do Betta Fish Need Light? As a betta fish owner, you may wonder whether your pet enjoys living in the dark or needs light. After all, betta fish are indigenous to Southeast Asia’s tropical, shallow seas, where they regularly expose to daylight.

But can Betta fish survive in an environment with little to no light, or do they require light to thrive?

Short response: The fact is that betta fish require some light to sustain their normal behavior and general well-being. Betta fish exposes to various lighting situations in their native habitat, from direct sunlight to filtered shade.

Artificial lighting can assist in simulating these circumstances in a home aquarium, enabling betta fish to exhibit their brilliant colors and engage in natural behaviors like swimming and investigating their environment.

Betta fish require light to survive, just like most other species. Thanks to sunlight, fish can better control their energy levels and sleep, feeding, and eating behaviors.

You can find betta fish in rice fields, streams, canals, and other murky waterways. Due to sunlight’s poor ability to penetrate the water, these habitats don’t offer much natural light. The sun may not be able to properly illuminate the fish due to a lot of material, such as falling leaves. Because of this, Bettas may thrive in low-light environments.

However, even though betta fish don’t require a lot of light, they still need some light to keep healthy. They make use of light to recognize food and fend off predators. Birds are their natural predators, and they swoop down to consume them. Bettas can detect predators approaching from a distance and have time to hide by being able to see the light bouncing off the water’s surface.

Betta fish in a tank doesn’t have to be concerned about predators, but they still require light to find food. Since most foods for Bettas locate atop the water, they must be able to see it to consume it.

Light also encourages Betta activity. Bettas in the wild are always swimming around in their native environments. They maintain their health and fitness through this activity.

Although captive Bettas may not get as much exercise because they don’t have as much room to swim around in, natural or artificial light still helps to increase their activity levels. According to one study, fish exposed to more excellent light were more active and had lower melatonin levels.

First things first: Betta fish have no sensitivities whatsoever toward light. They require light in their life, but unlike us, they cannot appreciate or recognize it.

In other words, light and Betta fish only interact in ways that benefit their bodies and everyday activities.

Light regulates the biological operations of Betta fish and keeps their color vivid and healthy. Like other fish, Bettas rely on sunlight to give them a sense of day and night, impacting how they eat and sleep. Bettas can grow lethargic and confused without light.

However, exposure to artificial solid lighting or direct sunshine can also cause stress or illness in some people. It means that giving Bettas enough light each day is essential to their well-being, but it’s crucial to understand how much light they require in the first place.

The bad idea is to keep your tank in direct sunlight. Direct sunshine may also heat the water in your tank, which could cause your Betta to become ill or practically cook, depending on where you reside.

Additionally, excessive algae development brought on by direct sunlight can result in unclean water in your tank, necessitating more frequent cleaning.

The most important thing to remember is that your Betta will thrive in a stable environment. It involves maintaining a consistent cycle of light and darkness for your fish. Living in a home like this for many years is in his best interest if you want your new little companion to be a happy and healthy betta fish.

Helps Bettas Stay Healthy

Light also has some significant health advantages for Bettas. According to one study, melatonin levels were lower in fish exposed to more light. A hormone called melatonin connects to both stress and sleep. Fish can maintain their activity levels and stay healthy by lowering the quantity of melatonin in their bodies.

Betta fish are accustomds to sleeping in total darkness in their native home. Intense illumination, frequently made up of the white and blue spectrums, can affect evening species like Bettas.

It makes sense if you want to admire your Betta’s beauty at all hours of the day. Therefore, it recommends using a low light if you’re going to study your Betta more closely at night so that you can do so without upsetting them. It can be a tiny nightlight or an aquarium light with a dimmer. 

A dim light should be on at night to assist the Betta in acclimatizing to a regular day/night cycle, which can support good behavior and a robust immune system.

Don’t worry if you’re concerned that your dogs won’t be able to see; while they may not have excellent night vision, they are susceptible to even the slightest variations in water pressure, which lets them “see” their surroundings.
