Betta fish tank light at night.

Betta fish need light to be truly healthy both physically and behaviorally. The main issue with this method is that betta cannot have a light on at night. Betta fish typically need 8 to 12 hours of light and 12 to 16 of darkness so make turning off your tank light a pre bedtime habit. It is possible to change the light to a dim blue but the fish will be healthier with a period of pure darkness.

Are you wondering whether you should leave your betta fish light on or off at night. Your betta will sleep with the light on and may nap during the day when the light is on. Your light source can be artificial or it can be natural as long as you avoid direct sunlight and light that might heat up the aquarium water. Too much sunlight can heat the water of your tank up to uncomfortable or dangerous levels and it can also increase the amount of algae which can cause bacterial infections.

The easiest way to do that is by turning the tank light on when you get up in the morning and switching it off when you go to bed at night. Additionally excess sunlight and regular light can lead to massive algae blooms. If your betta fish has too much light it can become overly stimulated and stressed. For tanks without live plants there is no need to have the light on more than 8 10 hours per day.

You ll see this stress play out in feeding habits mostly. However just like their wild cousins captive betta fish do need to sleep at night. You should aim to give your betta 8 12 hours of light and 12 16 hours of dark per day.
