Tip of the Day – 6/13/2013


Want to view your aquarium life at night, after the lights are off, but don’t want to disturb everything with the bright white light from a huge flashlight? Well, try a different color light. Due to the nature of light beams, certain colors don’t penetrate into the depths very well. While our aquariums will never be deep enough to filter the light out, the marine life have evolved over time to only be able to see certain colors. Low frequency light, like red light in the visible spectrum, doesn’t have the energy to penetrate deep down. So, many animals cannot see the color red. Because of this, red lights are ideal when viewing your aquarium at night. Sure, that color saturates everything and you don’t get to see the true color of your aquarium life, but the behavior of the fish and corals rarely change.
