Scientific name: Barbus nigrofasciatus

The very hardy Black Ruby Barb grows to two inches and needs plenty of room to swim. It also likes to have plants at the back and sides of the tank to take shelter in. The water temperature should be in the range of 72º to 82º Fahrenheit with a pH of 6.0 to 7.5 and moderately soft to mildly hard water. The Black Ruby Barb does well on all flake and freeze-dried foods.

Adult males are darker than females, and at breeding time their red coloration is greatly enhanced. Sometimes when males are kept together in a group, they will keep their breeding colors, perhaps as a form of competition.
