Black Skirt Tetra
The Black Skirt Tetra is a hardy and popular schooling fish known for its bold black coloration, flowing fins, and active personality. A longtime favorite in the aquarium hobby, this species is an excellent choice for community aquariums due to its adaptability, peaceful nature, and attractive appearance. When kept in groups, Black Skirt Tetras create a striking display as they school together through the aquarium.
Approximate Shipping Size: 1–1.5 inches
Appearance
Black Skirt Tetras feature a silver-gray body accented by distinctive black vertical bands and an elongated black anal fin that gives the species its common name. Their elegant finnage and contrasting coloration make them highly visible in planted aquariums. As they mature, their body shape becomes deeper and their markings become more pronounced.
Temperament & Behavior
These tetras are active, social fish that thrive in schools of six or more. Keeping them in larger groups encourages natural schooling behavior and helps reduce occasional fin-nipping tendencies. They spend most of their time in the middle levels of the aquarium and add constant movement to community setups.

Black Skirt Tetras are hardy and adaptable, making them an excellent choice for beginner and experienced aquarists alike. They appreciate planted aquariums with open swimming areas and stable water conditions.
