Put flakes and pellets directly into the water, and your fish will come to the surface and eat. If feeding vegetables or meat-based food, you have to chop them first before feeding.

Yes. Vegetables are a good source of nutritions Tetras can get in addition to meaty foods. Although they are carnivores, they occasionally need plant-based food to consume nutritions they can’t get from meat-based food.

In the wild, they eat plant matter to fulfill their need. In fish tanks, you have to provide plant matter from outside the tank, which is vegetables. However, occasional feeding is more than enough for Black Skirt Tetra.

Black Skirt Tetra Care Guide

Learning what to feed Black Skirt Tetra is not enough if you want a happy fish in your tank. In addition, you need to know about their habitat requirements, water parameters, tank mates, breeding, and more. We will teach you everything you need to know about Black Skirt Tetra from this guide.

Black Skirt Tetra Life Span

The average life span of Black Skirt Tetra is around 3 to 5 years in captivity. However, they tend to live much longer in the wild and prefer larger spaces that imitate natural habitats to live stress-free.

As they don’t get natural habitat in tanks and aquariums, their life span is reduced.

Black Skirt Tetra Typical Behaviour

Black Skirt Tetras are mid-tank swimmers that swim all across the tank to check out what’s happening inside the tank. They are schooling fish so, they tend to school together like a group of high school kids.

But, sometimes, some fish leave the group to have some alone time, to rest (or to think about something? I guess.), and it is so interesting to watch their behavior.

Black Skirt Tetras are peaceful fish species; however, they hate long-finned fish. They will be aggressive when they see long fins and turn into nip mode when they meet a long-finned fish.

Otherwise, they are pretty timid and will appreciate hiding places. They prefer an aquascape with Caves, tall plants, rocks, and wood to hide when there’s something odd going on.

Black Skirt Tetras

Black Skirt Tetra Preferred Habitat

Black Skirt Tetras are schooling fish, and they always are in a group. So, you need to keep at least six tetras together in a fish tank. The minimum tank size for Black Skirt Tetra is 15 gallons. They always appreciate more space as they love to spend the day swimming.

Black Skirt Tetra’s natural habitats are dark and have many hiding places such as rocks, plants, and wood. If you want them to live happily in captivity, you need to provide an aquascape that mimics this habitat. Otherwise, the fish get stressed.

For the substrate, always use dark-colored gravel or sand to mimic the dark bottom of their natural habitat. But, again, the substrate type doesn’t matter as Black Skirt Tetra rarely visit tank bottom.

You have to provide rocks, caves, wood, and tall aquarium plants in your aquarium if you keep Black Skirt Tetras in your tank. This is because they will use them as their hiding places when they get stressed.

Water Condition

Black Water Tetras are freshwater fish that need clean and subpar water conditions. Otherwise, they get stressed, making them more susceptible to disease. Their native habitats are in the rivers of South America. The waters of South American rivers are warm and somewhat acidic, so you have to recreate this water condition in your aquarium.

The optimum water parameters of Black Skirt Tetras are,

  • pH level: Between 6.0 to 7.5 
  • Water hardness: 4 to 8 dKH
  • Water temperature: 70°F to 85°F (21.1-29.4°C)

You have to check whether your tank water passes the marks. You should install a filter to keep ammonia and nitrate levels low.

We recommend testing the water condition often to ensure that the water meets their preferred water conditions and perform a 25-50% water change bi-monthly.

Black Skirt Tetra Tank Size

The minimum tank size for Black Skirt Tetras is 15 Gallons. You can keep six tetras in a 15-gallon tank.  As Black Skirt Tetras are schooling fish, you should keep a minimum of 6 fish in a tank. If you can provide at least 20 gallons of water for six fishes, that’s always better.

Black Skirt Tetra Tank Decorations

Black Skirt Tetras

With Black Skirt Tetras, you can get creative as much as possible with anything you want as Tetras doesn’t eat plants much and does not scavenge.

Plants

You can grow aquarium plants with Black Skirt Tetras.

We recommend choosing taller plants as they can provide an ideal environment for Black Skirts. Black Skirt Tetras are schooling fish that stick to the middle of the tank most of the time.

So, if you add taller plants, they will use the plants to explore and swim through, and they’ll appreciate it. And the plants will be great snacks between their primary meals.

However, do not overstock the tank with plants as they need more room to swim. Keep in mind that these fish are active swimmers and need some space to move freely.

The best way to provide both requirements is to keep the plants in the background and perimeter of the tank. With this method, you can provide enough open space for Black Skirt Tetras.

Substrate

The substrate should be darker in color because the dark-colored bottom mimics decaying leaves at the bottom of the streams they call home in the wild.

You can use any substrate as Tetras don’t go to the bottom often. Many fishkeepers use dark sandy substrate or river gravel.

Other Decorations

Adding many hiding places such as caves, rocks, and driftwood to the bottom of the tank is recommended because they can provide protection whenever the fish are feeling a bit shy or threatened.

Filtration System

You must install a strong filtration system to eliminate waste and keep Ammonia and Nitrate levels relatively low. Although Black Skirt Tetras don’t produce lots of waste individually, a large school can quickly alter the water quality.

Lighting

Black Skirt Tetras display more vibrant colors if you provide lighting. So, installing a lighting system is an excellent idea.

How Many Tetras per Gallon?

Black Skirt Tetras

Tetras need at least 15 gallons of water to thrive, and you can not keep one tetra in a tank as the fish will get stressed if kept alone.

So you have to maintain a minimum of 6 Black Skirt Tetras in a fish tank to keep them happy. And you can keep six tetras in a 15-gallon tank.

Black Skirt Tetras Tank Mates

Black Skirt Tetras are a relatively peaceful species. So, the best tank mate for Tetras needs to be peaceful as well.

Black Skirt Tetras are mildly aggressive with long-finned fish, but some varieties of Black Skirt Tetras also have long-flowing fins. So, if you keep these two varieties together, the long-finned fish will become targets of aggressive fish that might nip at their fins.

You can put less active tetras with Black Skirt Tetras such as Black Neon, Cardinal, and Neon Tetras. Bottom dwellers like Danios, Dwarf Cichlids, and Rasboras are also good choices because Black Skirt Tetras won’t bother swimming to the bottom.

Here is a list of ideal tank mates for Black Skirt Tetras.

  • Cory Catfish
  • Dwarf Gourami
  • Harlequin Rasbora
  • Honey Gourami
  • Neon Tetra
  • Bolivian Rams
  • Cardinal Tetra
  • Celestial Pearl Danio
  • Chili Rasbora

Conclusion

Black Skirt Tetras are easy-care fish that you can keep in your aquarium. They are peaceful and will eat anything you feed, and will thrive well in large freshwater aquariums. However, they need to stay in groups, so you have to keep at least six fish in a fish tank. Nevertheless, they will be an excellent addition to your aquarium if you enjoy schooling fish.
