The fish, up close
The Filamentous Barb, scientifically known as Barbodes semifasciolatus, is a striking freshwater fish species that showcases a slender body adorned with vibrant colours. They feature a silvery base colour with distinctive black horizontal stripes running along their sides, accented by elongated fin filaments that trail behind them, lending them their unique name. These filaments can grow quite long, adding to the visual appeal of this species. Filamentous Barbs are peaceful schooling fish that thrive in well-planted aquariums with ample swimming space.
Care guide
Use these notes to shape a setup around the fish, then speak with our team about the tank you have in mind.
Plan your setupBehaviour
These barbs are known for their active and social nature. They should be kept in groups of at least 6 individuals to prevent stress and aggression. Filamentous Barbs are generally peaceful towards other fish species but may exhibit some fin-nipping behaviour, especially if they are kept in too small of a group.
Tank planning
Maintain stable water parameters in the aquarium, including a temperature range of 22-26°C, pH around 6.5-7.5, and moderate water flow. Provide plenty of hiding spots among plants and driftwood, as well as open swimming areas for these energetic fish. Regular water changes and filtration are essential for their well-being.
