Longfin Rosy Barb

The Longfin Rosy Barb is a captive-bred variety of Pethia conchonius in which a genetic mutation produces greatly elongated dorsal, anal, pectoral, and caudal fins. Males still develop the full pink-red breeding colour. The elongated fins require slightly calmer water flow than the standard form and make them unsuitable with fin-nipping species. All other care requirements are identical.

Water: 18–25°C, pH 6.0–7.5, moderate hardness. Tank: 120 L minimum; gentle to moderate flow to protect flowing fins. Feeding: Omnivore; flake, pellets, frozen bloodworm, brine shrimp, and spirulina-based foods. Behaviour: Peaceful schooler; keep 6+ together; active but less frenetic than standard form. Compatibility: Avoid any fin-nipping species — the long fins are very vulnerable; pair with peaceful tetras, corydoras, and rasboras.
