What Makes Black Skirt Tetra Hardy?

The black skirt tetra is a hardy fish that can live in a variety of water conditions. They are mostly resistant to diseases and can withstand some amount of bullying from other fish. However, they are not immune to these things and should be monitored closely if kept in an aquarium setting.

One of the things that make black skirt tetra hardy is their genetics. They are bred to be resistant to a variety of diseases and can survive in water conditions that other fish cannot. Another thing that contributes to their hardiness is how they are raised.

When they are young, they are kept in secluded tanks with limited contact with other fish. This limits the amount of stress they experience and helps them grow into healthy adults.

Factors That Affect Black Skirt Tetra’s Health

There are various factors that affect the Black Skirt Tetra’s overall health. Let us look at the reasons that affect them.


The genetics of your fish play a big role in how hardy or susceptible it is to disease/problems. Fish who come from farms where overstocking occurs tend to be more susceptible due to breeding among family members which lowers genetic diversity making them weak against diseases.

The hardiness of the black skirt tetra is something that is passed down genetically. If you have a healthy and hardy strain of these fish, then they will be more likely to survive in other environments. However, if you are starting with unhealthy fish, then it will be more difficult to keep them alive.

Water Conditions

Black skirt tetra can tolerate a range of water conditions including harder water and warmer temperatures. They do best in a pH range of neutral to slightly acidic but can adapt to various levels within reason. It’s important that their water conditions are stable or they may become susceptible to disease.

Stress And Bullying

Black skirt tetra do well in most water conditions but prefer slightly acidic water with a pH level between six and seven point five. They can tolerate temperatures up to eighty-five degrees Fahrenheit but should not be kept in saltwater aquariums.

If black skirt tetra is kept in an aquarium setting with other fish, they may become stressed. This can lead to bullying by other fish and can cause them to become sick. It’s important that you do not overcrowd your tank. You should also learn that there are plenty of hiding places for the black skirt tetra.

Repeated Pregnancy

If a female black skirt tetra becomes pregnant more than once in a short period of time, her health degrades. This is due to the fact that she will be using up all her resources to sustain multiple pregnancies instead of focusing on her own health. I recommend that you do not overstock your tank with these fish if you want them to live long and healthy lives.


Although the black skirt is hardy, they can still fall prey to various diseases. Diseases that affect them most often are bacterial infections, ichthyophthirius (white spot), and parasitic infestations.

Black Skirt Tetra can be affected by a variety of parasites including anchor worms, flukes, white spot disease caused by protozoans called Ichthyophonasas well as Uronema marinum or Velvet Disease.


If you have too many fish in your tank, the black skirt tetra may become stressed. This can lead to them getting sick and even dying. It’s important that you do not overcrowd your tank if you want to keep these fish healthy.


Black skirt tetra is omnivorous and will eat a variety of food items including flakes, freeze-dried foods, live brine shrimp, bloodworms, and tubifex worms.

It’s important that they have a balanced diet with plenty of protein and vegetable matter. If their diet is not varied enough, they may become susceptible to disease.

When young, you should keep Black Skirt Tetras in tanks by themselves or with other Black Skirt Tetras. They may become stressed if they are kept in tanks with fish that bully them or swim around them constantly. If this happens, their stress levels will go up which can lead to sickness and even death.

How To Maintain a Tank For Hardy Black Skirt Tetra?

If you want your black skirt tetra to live long healthy lives, then it’s important that you maintain the water conditions of the tank at all times using dechlorinated tap water (not distilled) along with aquarium salt for cichlids on top of regular water changes every week/fortnight depending on how many fish there are in the tank.

Change Water Often

In order to keep the water conditions stable, you should change about twenty percent of their tank water weekly or fortnightly.

Maintain Water Temperature

You should also keep a close eye on the water temperature and make sure it doesn’t get too hot or too cold. A good range for these fish is between 72 and 85 degrees Fahrenheit.

Aquarium Equipment

If you are new to aquariums, it may be a good idea to get an aquarium test kit so that you can monitor the number of nitrates in your tank.

Problems While Raising Hardy Black Skirt Tetra

If your black skirt tetra faces bullying issues constantly by other fish in an overcrowded tank setting, they may become stressed and sick.

Infected By Parasites

This can lead to bacterial infection as well as parasites such as anchor worms and flukes. Hence, it will be difficult for them to recover without veterinary care.

Aggression and Cloudy Water

There are some problems that may occur while you are trying to raise black skirt tetra including cloudy water, aggression among the fish, and fighting between fry.

Overcrowding Issues

There are many problems that occur while raising black skirt tetras but most often they stem from overcrowding or poor water conditions. If their water quality is not stable and consistent, then this will lead to them becoming sick and even dying prematurely.

Overfeeding Issues

Also overfeeding your fish by giving them more food than what they need can cause sickness or death if left uncorrected for too long. This is because excess food particles rot on the bottom of the tank creating ammonia spikes that poison the fish leading to disease and eventually death.


Q: Can You Keep Black Skirt Tetras In Saltwater?

A: No. They cannot adapt to a marine environment because they are freshwater fish species. Moreover, these fish cannot live in saltwater tanks because it’s not the natural habitat for them. Also, they live in freshwater environments where there is plenty of vegetation for cover and space for schooling behavior (school
