Coral Fish tank under blue LEDs and normal lighting. - YouTube
Just added some new blue lights to my 4 ft fish tank for when the main light is switched off.
I have in fact tried a blue light lifted from a saltie tank and the nocturnal fish took much longer to emerge from hiding (perhaps as a result of the fish not blending in as well from a distance as they do with red light?)
Whole tank red lighting does not seem to illicit the same response as a point source light a small torch and the fish can be seen to emerge from their caves and move and feed quite readily (so its a pity I blew the transformer and am now back to only white/blue options)

White aquarium lights tend to be used as natural moonlights. Blue lights also can be used as moonlights but white is thought to be more natural. Moonlighting is a term given to lighting that simulates the glow a moon gives off at night. It can help stimulate reproduction in some corals and other invertebrates, even a few select fish and creates a more natural environment. Blue lighting can also be used as purely decoration purposes. Red lighting can be used to view nocturnal creatures without disturbing then since it seems that most can not see red light. You also can use the lights during the day to create different types of features in your tank. An example is putting one by a air stone and shining the light upwards creating blue, green, or red bubbles.I know your not supposed to believe everything you read, so can someone please discredit this since I love the look of a cool-white led over a tank and my moonlights. Although, if my fish will be blinded by 12 hrs of cool-white daylight followed by 12 hrs of blue moonlight, might have to make some changes.The benefits of using LED lights are many. They take less energy to run, in fact quite a bit less. LED aquarium lighting uses up to 80% less electricity than other aquarium lights. They also do not generate the heat that fluorescent light bulbs do. Another very popular plus is the fact that they last far longer than .
LED lights can be dimmed, and programmed, allowing for a natural dimming at sunset and the reverse at sunrise. This is particularly good for nocturnal fish, as a dim blue light can be left on the tank to simulate moonlight, and allow for feeding and viewing purposes. Last, but not least, they come in a variety of colors, which can be used to accent the tank in interesting ways.please need help Blue light is detrimental to you and lightly to your fish. Like you and other diurnal lifeforms plants also need a period of complete darkness. It does so by altering the natural patterns of light and dark in ecosystems. Your tank is an ecosystem
