Filament Barb (Dawkinsia filamentosa)
The Filament Barb is a lively and attractive freshwater species known for its shimmering body, subtle coloration, and the long filament-like extensions that develop on the dorsal fin of mature males.

Hardy and adaptable, Filament Barbs are a great choice for aquarists looking to add energy and character to their setup.
