Longfin Rosy Barb

Longfin Rosy Barb (Pethia conchonius var. “Longfin”)

The Longfin Rosy Barb is a selectively bred variant of the standard Rosy Barb, prized for its elongated, flowing fins and vibrant rosy-pink to red coloration in males. Native to South and Southeast Asia, this hardy fish thrives in cooler freshwater aquariums. Its lively swimming and peaceful shoaling behaviour make it a striking addition to community tanks, adding both color and movement without requiring heated water.
