Known for their unique fin, the Longfin Rosy Barb is best kept in soft, slightly acidic water that has at least 20 gallons.  In addition, these fish prefer to be in schools, and are better tank mates when they roam in large schools.
The Longfin Barb is great for African Cichlid Tanks, and they will truly add beauty to your tank.  If you choose to mate, simply stock a large number of fish in the tank together and they will pair off instinctively.
