Aquarium lights can illuminate fish colors, make it easier to spot tank problems and regulate your fish's sleeping and eating. All fish need periods of darkness, and turning the lights off at night will help you mimic your pet's natural environment.
Nocturnal fish particularly prefer dim blue lighting at night. The blue lights not only mimic moonlight and, thus, encourage more physical activity, but these also provide them with illumination. There's also the fact that blue light allows you, their human parent, to view them well.
Too much light causes more algae growth. Reduce the time the aquarium lights are on to eight hours, or a bit less if necessary, to help reduce the algae growth. ... But remember, you do not want to have too little light on for the aquarium plants, Direct sunlight tends to create more algae than does artificial light.
As for food, freshwater fish are quite capable of going for several days without a meal. Healthy adult fish can go for a week or two without feeding. ... That doesn't mean you should routinely skip feedings, but your fish can safely be left without food over a long holiday weekend.
The fish do not need light and it is best that your turn it off during the night. Leaving the light on can cause stress to fish as they need a period of darkness to sleep. Too much light will cause algae to rapidly grow and make your tank look dirty. So the short answer is no, do not leave your lights on.
