Black Ruby Barb (Purple-Headed Barb)

In the wild, the ruby barb lives in the cooler slow-moving forest streams that are shaded by heavy vegetation. The water is soft and acidic, and the stream bottom is sandy with a layer of mulm (organic detritus). Replicating these conditions in the aquarium is ideal. Keep the water temperature in the 72 to 79 degree Fahrenheit range and use floating plants to subdue the lighting. Use sand or small gravel for the substrate, preferably in darker colors. A live-planted tank is ideal, although artificial plants will also suffice. Open space for swimming should be provided, as well as plenty of hiding places. Ruby barbs will become pale in color, and skittish if there are no hiding places to make them feel comfortable.
