Black Skirt Tetra: A Classic and Hardy Community Dweller

Add the timeless elegance of the Black Skirt Tetra to your aquarium. These peaceful, schooling fish are known for their distinctive appearance and active swimming, making them a captivating addition to any community setup.

Overview

The Black Skirt Tetra (*Gymnocorymbus ternetzi*) features a unique rhomboid body shape, silver-grey coloration, and two prominent black vertical bars behind its gills. Its most striking feature is the large, flowing anal fin, often deep black, resembling a skirt. While the intense black fades slightly with age, their subtle contrast remains appealing. These active, mid-dwelling fish thrive when kept in groups, exhibiting lively shoaling behaviors throughout your aquarium.

Care Level

Considered an easy-to-moderate care level, Black Skirt Tetras are hardy and adaptable, making them suitable for beginners. They are generally peaceful but should be kept in a school of at least 6-10 individuals to prevent fin-nipping tendencies towards slower or long-finned tankmates.

Tank Essentials

A minimum of 75 litres is recommended for a healthy school of Black Skirt Tetras, though larger tanks provide more space for their active nature. Optimal water parameters include a temperature range of 22-26°C and a pH between 6.0-7.5. Provide ample open swimming areas along with dense planting and subdued lighting to mimic their natural habitat.

Diet

Black Skirt Tetras are omnivorous and unfussy eaters. Offer a varied diet of high-quality flake or granule foods, supplemented with live or frozen options like bloodworms, brine shrimp, and daphnia to ensure complete nutrition and vibrant color.
