Are guppies attracted to light?
Much research has been conducted on how female guppies choose their mates. Our results supported our hypothesis; male guppies were more attracted to females that reflected long wavelengths of light.
Does light pollution affect fish?
Now researchers in Germany have shown that light pollution at night can even disrupt important survival behaviors during the day. “We suspect that the nocturnal light causes a stress response in the fish, and fish generally increase their risk taking when experiencing stress,” says Kurvers.
Is blue light at night bad for fish?
Blue lights are good for fish at night. Because they mimic the moonlight, you can use them to create a transition from dusk to dawn and dawn to dusk.

Does light affect fish at night?
The answer is a big YES. You should turn off the light in your aquarium at night. Most fish require a period of light and darkness each day to thrive.

Do LED lights cause brown algae?
Member. Nope: doesn’t work that way. The wrong LEDs or the wrong fluorescents will create algae problems and direct sunlight is almost begging for algae. Even the right LEDs or the right fluorescents will create algae if the light is too strong without nutrient sufficiency (particularly CO2).
Are blue LED lights bad for fish?
Low heat output: LED lights do not generate the heat that fluorescent light bulbs do, and so they won’t heat up your aquarium water. 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.
Do blue LED lights cause algae?
Blue lighting can cause excess algae in freshwater and low Kelvin lighting, peaking in the red, can encourage algae in marine aquaria. Bulbs and tubes degrade over time, lowering their Kelvin rating, possibly causing more algae and producing light less useable by plants or corals.
What does the blue light do in a fish tank?
Blue light illuminates the aquarium and mimics the moonlight. It is used to mark the transition between dawn and dusk. Besides, blue light is calm, and it allows the edgy fish to venture out at night to search for food. Nocturnal fish prefer dim blue light at night when they are awake.
