Black Fin Rosy Barb Scientific Name: Pethia conchonius (selectively bred variant) Common Names: Black Fin Rosy Barb, Black-Tipped Rosy Barb Overview The Black Fin Rosy Barb is a striking color variation of the Rosy Barb, featuring characteristic rosy-golden body tones with distinct black markings on the fins—most notably on the dorsal and caudal fins. Known for its lively and peaceful nature, this barb is well-suited to community aquariums and brings both color and constant movement to the tank. Like other Rosy Barbs, it thrives in cooler, well-oxygenated water and is great for beginner aquarists.
