Betta Fish Need Light
In general, Bettas environment is dark, because of the thick aquatic vegetation that grows in the rivers, and due to this dense vegetation water gets stagnated and muddy. However, Betta fish eat from the surface of the water and they can easily breathe air when they are on the surface as they also use their labyrinth organ along with gills to breathe. That is why they are normally found on the surface of the water so that they can also live in bright natural sunlight. Wild Betta fish are very active during the daytime, but during the nighttime, Betta fish sleep throughout the night.
Aquarium Light In Captivity:
However, unlike wild bettas, captive bettas are normally kept in the best fish tanks for bettas, with bright aquarium light as fish keepers like to see the beautiful colors and form of the Betta fish. The captive betta fish can easily adjust to these lights also as they can see the offered food and they can avoid the light by hiding under the aquarium plants or caves.
Like wild bettas, captive bettas also sleep at night in their betta fish tank setup, which means you need to turn off the aquarium lights at night. During the daytime, you can turn on the lights in the fish tank and during the night turn them off when you go to sleep.
