Blue LED lighting creates a calming ambiance in your aquarium. Many fish enthusiasts say the blue light serves best as a transition light between light and darkness. So, you can use the light in the evenings to help your less curious fish to come out of the hiding spots as blue light mimics the moonlight.

Is blue lighting good for fish?

Blue light can affect fish reproductive cycles and damage their eyesight, but most fishkeepers have no blue light issues. Blue light is essential if you have live plants in your tank as without it, they will be unable to photosynthesize. However, too much light will fuel algal growth, which is hard to get rid of.

What color lighting is best for fish?

Red, blue and green LEDs are in popular use for standard aquarium lighting since these light temperatures greatly enhance the colors of the objects inside the aquarium. The colors of aquatic plants appear much more rich and vibrant, red fish, shrimp and of course red-leaved stem plants look much flashier.
