How To Take Care Of Black Skirt Tetra: The Ultimate Guide

Black Skirt Tetra is one of the most popular fish species in freshwater aquariums. They are very attractive and have great personalities. Black Skirts, like other tetras, move around in shoals and prefer to swim near the surface. Here we will discuss how to take care of black skirt tetra: what you need to know about them before purchasing them, how they should be cared for after purchase, and some tips on maintaining their health and well-being.

Clean water leads to happy fish. If you want your Black Skirt Tetra to be healthy, then you need to take care of the tank conditions by changing the water regularly and installing an appropriate filter system. It is also important that you feed them properly so they’re getting what they need for their overall well-being. And don’t forget about temperature control!

About Black Skirt Tetra

Black Skirt Tetra is a very popular fish species known for its great personality and brilliant colors. They are shoaling, mid-water swimmers that prefer to live in groups of six or more. Their black coloring with the iridescent blue stripe along the length of their body makes them stand out from other tetras.

How Do You Take Care of Black Skirt Tetra?

The way you take care of your Black Skirt Tetra will depend on a few factors, such as the size of their tank and what other fish live in it. Generally speaking, here are some things to keep in mind:

Clean water is key! Regularly change at least 25% of the water in your tank and monitor ammonia levels, pH levels, and general water quality. Install an appropriate filter system to help with this.

Feed them a balanced diet that consists of both meaty and plant-based foods.

Maintain a consistent temperature between 68 and 78 degrees Fahrenheit.

Black Skirts should ideally be kept in groups of at least six to eight, but they prefer even larger shoals (12 or more).

The Tank Size Your Black Skirt Tetra Needs

A good rule of thumb is to give each fish a minimum amount of space equivalent to one gallon per inch. If you want your Tetras to thrive and stay healthy, then the tank size needs are as follows:

For juvenile Black Skirt Tetra (less than two inches), provide them with around 20 gallons for every three small fish. For example, if you have 12 black skirts that measure about an inch long each, aim for a 60-gallon tank or bigger. Just remember that this doesn’t mean just filling it up halfway with water and fish! You’ll need room for plants, rocks, and other decorations too.

For adult Black Skirt Tetra (two inches or more), provide them with around 30 gallons per six fish.

Tank Mates

Adding other compatible fish to your tank can help make your Black Skirts feel at home and keep them entertained. Some good choices include:

  • Corydoras catfish,
  • Kuhli Loaches,
  • Danios,
  • White Cloud Mountain Minnows,
  • Zebra Danio,
  • Guppies,
  • Platys,
  • Swordtails.

Avoid keeping any species that is aggressive or overly active with the Black Skirts – they will become stressed and may not live very long.

Male To Female Ratio

It’s important to have a roughly equal number of males and females in your Black Skirt Tetra tank. If you have too many males, they will start to fight for dominance and can injure or even kill the females.

On the other hand, if there are not enough females then the males will become stressed and may die prematurely. A good rule of thumb is one male per every three females.

Balance The Water Parameters

It’s important to keep the water parameters in your tank balanced in order to maintain a healthy environment for your fish.

This means regular testing and adjustment of pH levels, ammonia levels, and general water quality as needed. You can use test strips or an aquarium water tester to help with this.

Changing Water For Your Black Skirt Tetra

When changing your Black Skirt Tetra’s water, make sure to remove around 25% of the old water and replace it with fresh, clean aquarium water that has been treated. If you need help figuring out how much new water you’ll need to add, use this equation:

Make sure to check the condition of the new replacement water for any impurities before adding it. This will help ensure that there are no adverse effects on your tank or its inhabitants.

Install Heater, Filter, And Other Equipment

It is important to keep an appropriate heater in your tank so they can maintain stable temperatures between 68-78 degrees Fahrenheit – especially if you live somewhere chilly! You also want a submersible filter (or several) because these will help keep the water clean and healthy for your fish. Other equipment you may want to consider installing includes:

A thermometer to monitor the temperature

An air pump and airstone to create movement and oxygenate the water

A timer to control when the heater and filter turn on/off

Feeding Your Black Skirt Tetra

Black Skirts are omnivorous, meaning they eat both plants and meat. Provide them with a varied diet that consists of both types of foods in order to give them all the nutrients they need. Some good ideas for Black Skirt Tetra food include:

-Live or frozen bloodworms, brine shrimp, daphnia, etc.

-Freeze-dried tubifex worms

-Small algae wafers or pellets, blanched vegetables like zucchini and spinach.

Taking Care Of Pregnant Black Skirt Tetra

If you have a pregnant female in your tank then it’s important to provide them with an appropriate place for their fry to hatch out of the egg sacs.

A good idea is to use either an incubator made specifically for fish eggs (like this) or just any small bowl that can fit inside your aquarium.

Just make sure to keep the water very shallow so they don’t drown! As long as you follow these guidelines, she should be able to take care of herself without too much interference from you.

Maintaining The Tank

Now that your Black Skirt Tetras are all settled in and happy in their new home, it’s important to remember to keep an eye on the water quality and make sure everything is running smoothly.

To do this, you should test the water parameters at least once a week using a kit from your local aquarium store – just follow the instructions that come with it for best results. If anything seems off (e.g. ammonia levels are too high), then take appropriate measures to correct it as soon as possible!

Prevent And Treat Diseases

Black Skirt Tetras are not particularly prone to getting sick, but there is always a chance that your fish could get ill or injured. If you do notice any abnormal behavior (e.g swimming in circles), fuzzy patches on their skin, or other symptoms of disease then it’s time for some quick action!

Here are the most common Black Skirt tetra diseases and what can be done about them:


This condition causes scales to stick out along with swelling near the belly area where they eat. It’s caused by an internal bacterial infection that can’t really be cured, but will usually resolve itself if treated properly with antibiotics like Kanamycin Sulfate.


Symptoms include small white spots on the body and fins which can easily be treated with medication like Ichthyozole.

Fin Rot

This is also caused by bacteria and will result in frayed or rotting fins. Treatment typically involves antibiotics as well as keeping the water clean and free of stressors.

Fungal Infection

If your Black Skirt Tetra starts to exhibit signs of fungus (e.g white patches on the body), then you’ll need to use a fungicide like Methylene Blue to get rid of it.

Why Taking Care Of Your Black Skirt Tetra Is Important?

As we’ve seen, taking care of your Black Skirt Tetras is not only important for their health and happiness, but also for you to properly maintain your tank! It’s a big responsibility that should not be taken lightly because these fish can live up to 15 years if cared for properly.


Q: Are Black Skirt Tetra Hardy?

A: Yes – in general, they’re very hardy when it comes to water parameters, temperature changes, etc. They are generally considered “fish-safe” which means they will survive even in relatively polluted or dirty tanks where other species might die off from the toxins/contaminants present in the water.

However, there is still a chance of them getting sick due to stress (e.g caused by frequent aquarium maintenance). So make sure you follow all of our advice on how to properly take care of your Black Skirt Tetras!

Q: Can Black Skirt Tetra Change Their Gender?

A: No – in general, most tetras can’t change their gender. However, there are some species/varieties that have been known to exhibit slight differences in coloring between males and females (e.g red-tailed black sharks).

So it’s not unheard of for specific varieties or breeds. Make sure you know what kind of fish you’re getting if this is important to you!


Now that you know all there is to know about Black Skirt Tetras, it’s time to get started on setting up your very own tank! Just make sure to do your research and follow all of our guidelines for proper care – with a little bit of effort, you’ll be able to create a beautiful and thriving aquarium ecosystem.
