Yes. Black Skirt Tetra Need Light At Night. However, it is not absolutely essential.

What Happens If Your Black Skirt Tetra Gets Too Much Light (Or Not Enough)?

If your black skirt tetra gets too much light, they may become stressed and their colors may fade. On the other hand, if they don’t get enough light, they may become weak and have trouble swimming properly.

Too Much Light

If your black skirt tetra is exposed to too much light, they may become stressed. If the stress continues long enough, their colors will fade and you might notice that they are not swimming properly or acting like themselves (swimming erratically).

Not Enough Light

Black Skirt Tetra needs some amount of sunlight but if it doesn’t get any at all then its energy levels can drop dangerously low. Without proper lighting, your fishy won’t be able to absorb nutrients from food as quickly which means poor growth and a weakened immune system.

Why Is Circadian Rhythm Beneficial For Black Skirt Tetra??

Circadian rhythm is important for all living organisms, including fish. It tells the body when to do certain things like eat or get ready to reproduce. If black skirt tetra doesn’t have this internal clock, they won’t be able to function properly and might become sick even though they are in a healthy environment with proper food and water quality.

Circadian rhythm is essential because it helps the body to know when it should eat, sleep, and reproduce. If black skirt tetra doesn’t have a circadian rhythm, they will not be able to function properly which could lead to health problems such as poor growth or an impaired immune system even if everything else is perfect in their environment.

How Much Amount Of Light Is Good For Black Skirt Tetra?

The optimal amount for most aquariums is about five hours on each side of the tank with both lights on at the same time. This will provide your fish with all they need to absorb nutrients and stay healthy while also giving them a break from light if it’s too much for them.

Which Light Is Best For Your Black Skirt Tetra?

You can use either natural or artificial lighting in your black skirt tetra aquarium, but keep in mind that some types of lights are better than others depending on where you want the light to be positioned inside your tank (top vs bottom). Also, make sure there is a way for your fishies to swim away from direct sunlight when they get tired of being under bright lights.

Black skirts do best with fluorescent lighting like T-12s (long bulbs) because they can provide more light than other types of aquarium lights without producing too much heat. Your fishy will also need some type of daylight lamp for at least six hours every day so that its internal clock stays regulated and it has enough energy production throughout the day.

You can use  NICREW Classic LED Aquarium Light in your tank. This is the best one I have used so far. It consists of changeable lights so that you can dim and increase the brightness according to need.

Can You Use Sunlight Instead Of Artificial Light?

Yes! Some people prefer using real sunlight instead of artificial lighting. I’m not a fan of this because it has the potential to cause more problems around your house or around your aquarium if you don’t have proper equipment that can properly filter and dissipate the sunlight before it enters your tank.

Things To Keep In Mind Before Installing Light In Your Black Skirt Tetra Tank:

  • Make sure you have a light that is appropriate for the tank size. There are lights built specifically for tanks of various sizes. As a result, it’s useful if your Ember Tetras require more or less space!
  • Make sure there’s no danger of fish jumping out of the water to get to food if they’re too close to the light.
  • Keep in mind that if your tank is near any other sources of light or electrical equipment, there may be a risk of overheating. As a result, it’s advisable to place lights on the opposite side of the room from the televisions and laptops!
  • Consider if you want an LED or a fluorescent light bulb; each has its own set of advantages.
  • To make your Ember Tetras feel more at ease and at home, try adding some plants to the tank.
  • It’s best to avoid switching lights too frequently, as this can cause problems.
  • Black Skirt Tetra needs at least two hours of natural sunlight or five hours on each side with both lights on.
  • If possible, try to position the light source underneath your tank (bottom) instead of over it (top). This will give them more control over how much light they receive depending on where they are positioned in their aquarium.
  • Make sure there is enough room for fishies to swim away from direct light.
  • You also want to make sure they will be able to get back into bright lights without too much trouble (some tetras are skittish).
  • Also, remember that some types of lighting may need special bulbs so keep an eye out for those!


Can Light Regulate Temperature In Black Skirt Tetra Aquarium?

Yes, light can help regulate the temperature in your black skirt tetra aquarium. This is especially helpful if you’re using artificial light because you can control how much heat the light emits.

How Many Hours Do Black Skirt Tetra Sleep?

Black skirt tetras usually sleep for around eight hours a day. This means that they will be most active during the daytime when there is more natural sunlight available to them.


As you can see, it’s important for black skirt tetra to have some amount of light at night so make sure you provide them with what they need! Whether you decide to use artificial or natural lighting, just be sure to keep an eye on how much light is too much for your fish and make adjustments as necessary. Thanks for reading!
