Do LED lights bother fish?

Fish are not as reliant on light as plants. In general, aquarium owners can use incandescent, fluorescent, or LED lights for fish but should be aware of the heat issues that incandescent lights cause.

Can lights be too bright for fish?

What Colour light stops algae growth?

Our results show that algae grows the best under white light and more in blue light than red light. Therefore, our hypothesis is partially supported because the growth rate was higher under the blue light in comparison to the red group; however, the algae under the control condition experienced the most growth.
