Fish's preferences for light vary depending on the species of fish and their living habits. Here’s a closer look at fish’s preferences for light:
Day and night rhythm:
Most freshwater and saltwater fish have a diurnal rhythm, which means they are active during the day and rest at night. Therefore, daytime light is very important for these fish, and they have certain requirements for the presence and intensity of natural light.
Ecological adaptation:
Some fish have adapted to ecological environments that require relatively weak light, such as deep-sea fish. These fish usually live in the deep sea and are rarely exposed to natural light, so they are not sensitive to strong light.
Sink and light:
For fish keepers, it is very important to provide proper lighting in a home fish tank. Light can affect fish behavior, color and overall health.
The light provided in the fish tank must be moderate. Too strong or too weak light may have adverse effects on the fish.
Color and Vision:
Some fish species are very sensitive to changes in color and light, which plays an important role in their courtship, reproduction and foraging.
Too strong or too weak light may affect the vision and color recognition of fish, thereby affecting their behavior.
In general, fish’s preferences for light vary depending on their ecological adaptations and living habits. Providing proper lighting is important for fish behavior, health and quality of life. When raising fish, understanding the light needs and preferences of different types of fish and providing a suitable lighting environment will have an important impact on their growth and health.
