Amapá tetra
Hyphessobrycon amapaensis
A small Brazilian tetra with a scarlet red line along the flank contrasting with the silver-gold body — an elegant, refined chromatic effect. Native to savanna streams in Amapá state in northeastern Brazil. Less known than more famous cousins but with a subtle charm and remarkable longevity (about 5 years). Prefers acidic, very soft water with moderate lighting. In schools of 6+ on dark substrate with dense vegetation, the red line stands out like a brushstroke.
