Black Skirt Tetra

Black Skirt Tetra requires a minimum of 20 gallons for healthy adults. The minimum is based on the species' adult size (2 inches), territorial range, and behavior pattern. Most Black Skirt Tetra sold at small juvenile size will reach full adult size within 12-24 months and the system must be sized to the adult, not the juvenile.

The Black Skirt Tetra needs a tank of at least 20 gallons, a temperature of 74-80°F and pH 6.5-7.5. Adults reach about 2 inches and live 3-5 years. Best paired with peaceful tankmates of similar size and water-chemistry needs.

Black Skirt Tetra prefers freshwater parameters: Temperature: 74-80°F pH: 6.5-7.5 GH: 4-12 dGH KH: 3-8 dKH Ammonia + nitrite: Both 0 ppm Nitrate: Under 20 ppm long-term Copper: 0 (especially critical for invertebrates) Use dechlorinator on every water change. Test parameters weekly during cycling, biweekly once stable. Stable consistency beats sliding-scale "ideal" parameters.

Black Skirt Tetra is a omnivore. Eats a varied diet of pellets, frozen foods, and supplemental greens. Quality flake or pellet (Hikari, New Life Spectrum, Tetra) plus frozen mysis or bloodworms 2-3x weekly produces best color and behavior. Feed Black Skirt Tetra appropriately for its size + activity level.

Black Skirt Tetra works in community tanks with peaceful species in similar size class. Adult-size matters more than purchase-size when planning stocking. Avoid mixing aggressive with passive species. Browse care guides for tankmate-compatibility tables for Black Skirt Tetra and similar species.

Black Skirt Tetra reaches 2 inches at adulthood with a captive lifespan of 3-5 years with proper care. Most freshwater species live 3-10 years; larger species (oscars, plecos, knifefish) reach 10-20+ years. The minimum is based on the species' adult size (2 inches), territorial range, and behavior pattern.

Black Skirt Tetra is susceptible to standard freshwater diseases (ich, columnaris, fin rot, bacterial infections). Quarantine new Black Skirt Tetra for 4 weeks before adding to your display tank. Treat fish in a separate hospital tank to avoid affecting plants and inverts. Most disease outbreaks trace back to poor water quality, chronic stress, or skipped quarantine.

Black Skirt Tetra (Gymnocorymbus ternetzi) is native to specific tropical and subtropical freshwater systems. The captive-bred Black Skirt Tetra sold at most LFS comes from generations of farmed stock and is generally hardier and better-acclimated to tank conditions than wild-caught equivalents. Wild specimens are occasionally available for keepers chasing original-bloodline coloration or biotope-accurate stocking.
