What does blue light do for fish tank?

One of the most common concerns of fish owners is the health of their fish. One of the things that can impact fish health is the level of light exposure they receive.

In general, blue light is known to be less harmful to fish than other colors of light. This is because blue light has a shorter wavelength than other colors, and is absorbed by the skin and eyes more slowly.

When blue light is absorbed by fish, it can cause them to release histamine. Histamine is a chemical that can cause a wide variety of problems for fish, including making them swim in an erratic or frenzied manner, making them more susceptible to disease, and making them more prone to dying.

Therefore, it is important to make sure that your fish tank receives a consistent level of blue light exposure. This can be done by using a blue light filter, or by simply being aware of the light that is coming into your tank and choosing light fixtures that emit blue light.
