Rosy Tetra

Rosy Tetra (Hyphessobrycon rosaceus) is native to specific tropical and subtropical freshwater systems. Captive-bred specimens at most LFS come from generations of farmed stock and are generally hardier and more colorful than wild-caught equivalents.

Rosy Tetra requires a minimum of 20 gallons for healthy adults. The minimum is based on 1.5 inches adult size and territorial range. Plan a tank sized for adult footprint, HOB or canister filter rated 4-6x volume, dechlorinated water, appropriate temperature heater, and stocking-appropriate hardscape.

Rosy Tetra prefers freshwater parameters: temperature 74-80°F, pH 6.5-7.5, GH 4-12 dGH, KH 3-8 dKH, ammonia + nitrite 0 ppm, nitrate under 20 ppm. Use dechlorinator on every water change.

Rosy Tetra is a omnivore. Provide a varied diet of pellets, frozen foods, and supplemental greens. Feed twice daily in small portions. Browse our food guides for product recommendations.

Rosy Tetra works in community tanks with peaceful species in similar size class. Avoid mixing aggressive with passive species.

Rosy Tetra reaches 1.5 inches at adulthood with a captive lifespan of 5-8 years with proper care.

Rosy Tetra can be bred in dedicated breeding tanks with appropriate setup and water-chemistry triggers. Research the species-specific breeding requirements before attempting.

Rosy Tetra is susceptible to standard freshwater diseases (ich, columnaris, fin rot, bacterial infections). Quarantine new Rosy Tetra for 4 weeks before adding to display.

Rosy Tetra is sold at LFS, online retailers, and direct from breeders. Browse live Rosy Tetra from vetted Fast Aquatics vendors with carrier-tracked overnight shipping, climate-aware hold logic, and a 4-hour DOA window with photo-evidence claims.
