Many fish owners wonder if it’s a good idea to turn off the light in their aquarium at night. It’s important for your aquatic pets’ health and wellbeing as much as it is to save electricity. Like all living things, fish have natural rhythms, and one of the most important factors in these cycles is light.
Fish in the wild go through regular cycles of light and dark. You can keep your aquarium stress-free and healthy by modeling this behavior. Their natural behavior can be disturbed by constant light, which can result in issues like heightened aggression, sleep deprivation, or even ill health.

Do fish need light
Some fish species don’t require lighting at all, either during the day or at night. If the water is deep enough, they live on the bottom or in the water column. As a result, very little light gets there. Catfish, for instance, are nocturnal creatures that detest light. These fish have a great sense of smell in the dark.
However, some aquarium animals require light to survive. For instance, goldfish in the absence of light will turn pale, drowsy, refuse to eat, and eventually become ill.
In general, the most natural conditions must be created for pets in order for them to live comfortably; day and night must exist in a home pond. Depending on its intensity, the aquarium’s light must shine for approximately 12 hours every day to achieve this.
Do plants need light
Plants require light to grow. The aquarium light needs to be on for eight to twelve hours in order for them to develop. They create oxygen, take in carbon dioxide, and grow during this period—this is the process of photosynthesis.
The kinds of crops planted in the aquarium are taken into consideration when choosing the lighting’s brightness. For instance, with illumination of 30–40 lm/l, cryptocarine, anubias, and corneal will grow perfectly. However, some plants are more demanding and require much brighter light. For instance, one lemongrass must light 100 lm/l in order for red plants to grow. Plants don’t require light at night.
What problems will appear if you leave light on the night on
Numerous issues will arise from the aquarium’s round-down lighting. The most prevalent ones are listed here:
- Some species of fish in round -the -clock lighting will be in a state of stress. Over time, this will lead to the fact that they will attack each other.
- Due to an excess of light in the aquarium, algae will begin to grow. Over time, such a container will look dirty and ugly. The growth of algae will lead to the death of plants.
- Fish, like other living creatures, need darkness for sleeping. If they do not rest, they will become inactive.
It’s essential to turn off the light in your aquarium at night in order to keep your fish and plants in a healthy environment. Fish require a natural day-night cycle to survive, just like humans do. They become stressed and sleep ill if the light is left on all the time, and plants require darkness to perform certain necessary functions. Therefore, it’s best to turn off the aquarium light at night for the health of your aquatic life as well as the surrounding vegetation.
How to control the light
You can use a light electronic timer to create day and night in the tank. It is programmed to switch the light on in the morning and off in the evening. This is a reasonably practical method, as you won’t have to worry about forgetting to turn on or off the lighting once it is set up. Each day, the timer will take care of this for you.
Invest only in top-notch equipment to prevent home fires. The timer works on the principle that a spark will occur if there is poor contact between the relay and the electrical circuit, which it closes or opens. Similar to a clock, a mechanical timer counts down by winding the spring for eight hours, at which point it opens the electrical circuit.
Regarding the alternative approach, its foundation lies in your personal responsibility to switch on the aquarium’s light in the morning and turn it off at night. However, it is best to set the daylight mode and do all of this at the same time.
As you can see, there is a straightforward response to the query of whether nighttime lighting in an aquarium is necessary. Neither fish nor plants require light at this time of day.
