Overview
What to know before you buy.
The Black Skirt Tetra is a popular and hardy fish, known for its distinct, high-backed body shape and black 'skirt-like' anal fin. As they age, their black coloration may fade to a silvery grey. They can be fin-nippers, so avoid keeping them with long-finned, slow-moving fish.
Key traits
Care guide
Keeping Black Skirt Tetra healthy in a South African setup.
Tank setup
Size the aquarium to Black Skirt Tetra's adult size and activity level. Use robust décor and sight breaks so each fish can hold its own space.
Water parameters
Keep pH 6–8 and 22–26°C. Stable parameters matter more than chasing perfect numbers; acclimate new arrivals slowly.
Feeding
Omnivore. Feed small amounts it clears in a couple of minutes, and vary the diet.
Behaviour
Semi-aggressive. Keep it in a group for natural behaviour.
Tankmates
Choose robust tankmates of similar size, and nothing small enough to be eaten. Add Black Skirt Tetra last so territories reset.
Breeding
Breeding success with Black Skirt Tetra depends on the line and water chemistry; ask your shop about proven pairs.
Settling this fish in?
Condition the tap water, seed the filter, test through the first weeks — most early losses trace back to one of those.
