Emerald Rasbora (Danio erythromicron)
The Emerald Rasbora (Danio erythromicron), also called Emerald Dwarf Rasbora, is an exquisite nano fish that brings subtle elegance to planted aquariums. This close cousin to the Galaxy Rasbora features a more delicate appearance with turquoise-green flanks, bright orange vertical bars on the body, and vibrant orange accents on the fins. Their understated beauty makes them perfect for naturalistic aquascapes.
Reaching approximately 1 inch in length, Emerald Rasboras are slightly more timid than Galaxy Rasboras but equally rewarding for patient aquarists. Males display intense colors during courtship, creating living jewels as they dart between plants. These gentle fish are perfect for peaceful nano community setups with other small, non-aggressive species.
Like their celestial cousins, Emerald Rasboras hail from Myanmar's highland streams and prefer cooler temperatures (68-75°F), making them excellent choices for unheated tanks in climate-controlled homes. They thrive in planted aquariums with soft to moderately hard water (pH 7.0-7.8) and appreciate areas of gentle flow alongside calm zones.
