Black Skirt Tetra Fish Guide
The Black Skirt Tetra is a small, round-bodied fish with a shiny silver body and a dark “skirt” of black along its fins. People love them because they move in groups, make tanks look lively, and are fairly easy to care for. They are also called Black Widow or Petticoat tetra.
Origin
- Native to rivers in South America (mainly the Paraguay basin)
- They became popular in aquariums long ago because they adapt well to home tanks
Black Skirt Tetra Temperament
- Generally peaceful and curious.
- Schooling fish: they feel safe and look best in groups.
- Can nip fins if kept alone or stressed, so group size matters.
Compatibility
Good tank mates:
- Cardinal Tetra
- Harlequin Rasbora
- Dwarf Gourami
- Neon Tetra
- Celestial Pearl Danio
- Honey Gourami
- Chili Rasbora
- Cory Catfish
- Bolivian Rams
Avoid
- Slow-moving long-finned fish (like fancy bettas or angelfish with very long fins) and very small fry that might be eaten
Black Skirt Tetra Price in India

As with any other fish, the Black Skirt Tetra can suffer from decreased health if water conditions, diet, or stress levels are unsatisfactory. Black Skirt Tetra common health issues and their treatments are as follows:
Ich (white spot disease)
Ich shows as tiny white dots on the body and fins and makes fish scratch against objects. To treat, raise the water temperature slowly for a few days and use a reliable ich medication as directed on the package. Keep water clean and do small water changes during treatment to reduce stress. Early treatment usually clears it quickly.
Fin rot/Torn fins
Signs of fin rot are a frayed or discolored edge on the fin. If a fish appears to have torn fins from nipping, separate the overly aggressive fish and perform partial water changes. You can give antibacterial aquarium medication if the edges look fuzzy or are infected. But vitamins in the diet can help regrow fins, as can good water quality and fewer stressors.
Swim bladder problems/bloating
A fish that swims or floats in a disorganized fashion may have swim bladder disorders, which can be caused by overfeeding or constipation. Fast the fish for 24-48 hours, and after that, give a very small piece of skinned, cooked pea to clear the gut. Ensuring good water quality and a varied diet can prevent recurrences.
Black Skirt Tetra General health tips
- Changing some of the water regularly and partially (20-30% weekly) will keep pollution from rising to high levels
- New fish should be quarantined for at least a week prior to being added to the tank
- Watch for your school's early warning signs, including sudden hiding, clamped fins, and loss of color
- Sufficient nutrition and stable water conditions prevent most diseases
