The Filament Barb (Dawkinsia filamentosa) is a stunning mid-sized tropical fish named for the delicate “filaments” that extend from its dorsal and tail fins. These peaceful barbs are active swimmers and show off their best colours when kept in schools in spacious, well-decorated tanks.
Their silver-gold body with red and black accents makes them an eye-catching centrepiece for planted or community setups.
