Nocturnal animals are most active at night. This is when they hunt for food and mate. So, do aquarium fish need light at night?
The answer is yes and no. It depends on the species of fish. Some fish are strictly nocturnal, while others are diurnal (active during the day).
There are also some that are crepuscular, meaning they’re most active during dawn and dusk.
As aquarium fishkeepers, we often ask ourselves whether our fish need light at night. The answer is not a simple yes or no – it depends on the type of fish you have and their natural habitat.
If you have fish that come from rivers or streams, they are used to varying light conditions and may be fine without any light at night.
However, if your fish come from lakes or ponds, they are used to a more constant level of light and may benefit from having a night light in their tank.
There are also some species of fish that are active at night and prefer dim lighting during this time. These include catfish, loaches, and some cichlids.
If you have any of these types of fish in your aquarium, you may want to consider providing them with a low-level nightlight.
In general, it is safe to say that most aquarium fish do not need bright lights shining on them 24 hours a day. A few hours of daylight each day is usually sufficient for most species.

Do Aquarium Fish Need Light At Night (Probably Not What You Think)
Do Fish Need Blue Light at Night
If you’ve ever wondered why your fish seem to be more active at night, it’s because they are. Fish are nocturnal creatures, and in the wild they would be exposed to blue light at night from the moon and stars. In a home aquarium, however, there is no natural source of blue light.
This is why many aquarium owners choose to use a blue LED light to simulate moonlight and help their fish feel more comfortable and active at night.
But do fish really need blue light at night? The answer is yes and no.
Blue light does have some benefits for fish, but it’s not essential for their survival. Here’s what you need to know about using blue LED lights in your aquarium:
Benefits of Blue Light for Fish
Blue light has been shown to have some positive effects on fish behavior and health. For example, exposure to blue light has been shown to:
– Stimulate appetite
– Increase activity levels
Why are My Fish More Active When the Light is off
Many people believe that their fish are more active when the lights are off because they can’t be seen. While this may be true in some cases, there are other reasons why your fish may be more active at night.
One reason is that the water temperature is usually cooler at night, so your fish may feel more comfortable swimming around.
Another reason is that there is less light pollution at night, so your fish may be able to see better and explore their tank more.
If you notice that your fish are more active at night, try turning off the lights for a few hours each day and see if they start to become more active during the day as well.
Can I Leave My Aquarium Light on 24/7
An aquarium is a great way to bring some beauty and relaxation into your home. But did you know that there are actually benefits to leaving your aquarium light on 24/7? Here are a few reasons why you should consider making this switch:
1. Your fish will be happier. Fish are naturally nocturnal creatures, so they feel more comfortable and relaxed when there is a constant light source in their environment. This also means that they will be more active during the day, which can be fun to watch!
2. Your plants will thrive. Many aquatic plants need 12-14 hours of light per day in order to grow properly. By leaving your aquarium light on all the time, you’ll ensure that your plants have the light they need to stay healthy and vibrant.
3. It’s easier on your schedule. Let’s face it – we’re all busy these days and it can be tough to remember to turn the aquarium lights on and off every day. If you leave them on 24/7, you won’t have to worry about it!
Of course, there are a few things you should keep in mind if you decide to leave your aquarium light on around the clock:
1. You’ll need to use an aquarium hood or cover to prevent evaporation and keep unwanted critters out of the tank (like flies).
2. You may want to invest in a timer so that the lights automatically turn off for a few hours each night – this will give your fish some time in “darkness” as well as help reduce evaporation even further.
Do Goldfish Need Light at Night
As you probably know, goldfish are a type of freshwater fish that are popular pets. They come in a variety of colors, and can grow to be quite large – some reaching up to 18 inches in length! Goldfish are generally very low-maintenance pets, and don’t require a lot of care.
However, one question that many people have is whether or not goldfish need light at night.
The answer to this question is yes and no. Technically, goldfish do not need light at night in order to survive.
However, if you want your goldfish to thrive and be healthy, it’s a good idea to provide them with some kind of light source during the nighttime hours. This is because goldfish are active during the day and night, and need a consistent light cycle in order to stay healthy.
If you don’t provide your goldfish with any light at night, they may become stressed out which can lead to health problems down the road.
So, while technically they don’t need light 24/7, it’s still best practice to provide them with some kind of lighting during all hours of the day (including at night).

Is It Ok for Fish to Be in the Dark?
It is certainly ok for fish to be in the dark, as they would naturally be in their wild habitats. Fish typically don’t see a great deal of light anyway due to the way that light refracts in water. In addition, many fish species are nocturnal, so being in the dark doesn’t phase them at all.
If you are keeping fish in an aquarium however, it’s important to provide some sort of lighting so that you can see them and they can get used to a regular day/night cycle.
Do Fish Need Total Darkness at Night?
No, fish do not need total darkness at night. In fact, many fish are nocturnal and actually prefer dim lighting. However, there are some fish that do need complete darkness in order to sleep.
These include species of flatfish like flounder and halibut.
Conclusion
No, aquarium fish do not need light at night. In fact, it is best to turn off the lights in the aquarium at night so the fish can get some rest.
