The term “black skirt widow fish” likely refers to the Black Skirt Tetra, also known as the Black Widow Tetra. This is a popular freshwater aquarium fish known for its striking appearance and relatively easy care requirements.
They typically have a black and silver body, with a distinctive black “skirt” or band running vertically across their body.
Their fins are usually black and can appear quite large and flowing, contributing to the “skirt” look.
They grow to about 2-3 inches (5-7 cm) in length.
Native to South America, particularly the Paraguay and Guaporé River basins.
Prefer soft, slightly acidic to neutral water. A tank with plenty of plants, open swimming space, and a gentle water current mimics their natural habitat.
Generally peaceful but can be fin nippers, especially when kept in too small a group or tank. It’s recommended to keep them in schools of at least 6-8 to minimize aggressive behavior.
They are compatible with other peaceful fish of similar size but may nip at slow-moving or long-finned fish.
Omnivorous, they accept a variety of foods including flake food, frozen, and live foods like brine shrimp or daphnia.
