    it all depend on the time of day, leave it off when it is day and at night turn it on for the little fish

    Like everyone else, bettas need night and day. So leave the lights on for 10-12 hours a day, and then turn them off.

    A 5$ timer you can buy at any Walmart is a great purchase. You can set it and forget it, so to speak.

    i have heard that you should turn lights off at night so they have day and night

    You need to simulate exactly what happens in nature. Keep the light on during the day and switch it off at night.

    If your tank receives a lot of natural light, you don’t need artificial ones, but if it’s in a corner with no natural light source, artificial lights should be turned on for about 8 hours during the day, off at night.

    honestly he will like it better with the light off, however if you have him in a small tank and the light is the only source of heat you may want to keep it on for about 9 hours to try to maintain a water temperature of 80F

    It depends, saltwater fish like dark water, like the ocean, but freshwater fish like it light. Fish mostly only see color blobs, so a saltwater fish will like dark colors, freshwater will like light.

    I turn mine off when I go to bed, on when I get up. Seems to work out for everything in the tanks.

    Keep the lights on during the day, and a little into the night, keep them off during the time you sleep, fish also like to sleep. I’ve noticed my betta likes it when the lights are on, mainly because he sits at the bottom under plants at night. Way more active during the day though.

    when the sun goes up turn them on when the sun goes down turn them off.
