Red Fin Torpedo Barb (Acrossocheilus fasciatus)

Red Fin Torpedo Barb — Acrossocheilus fasciatus

River speed with razor-clean contrast

The Red Fin Torpedo Barb is a streamlined, high-current cyprinid built for motion. A sleek silver to gunmetal body is accented by a sharp dark lateral band, while the dorsal, caudal, and pelvic fins glow with vivid red highlights. When kept in proper groups, the red intensifies and flashes brilliantly as the school turns in synchronized bursts.

Native to fast-flowing rivers and streams of East Asia, Acrossocheilus fasciatus thrives in oxygen-rich water with steady current. Its torpedo-shaped body and forked tail are engineered for endurance, allowing it to cruise midwater constantly rather than hover or lurk. In large aquariums, a school creates a clean, river-style aesthetic full of movement and energy.

Growing to approximately 6–8 inches, this species offers bold pattern and activity without reaching monster size, making it ideal for large river-themed community systems.
