Wild Karnataka Roseline Shark/Barb (Sahyadria denisonii)


A fish with many names, the Roseline Barb, Redline Torpedo Shark, or Denisonii Barb is a vividly colored schooling fish found in the fast moving streams of Western India. With their peaceful, active nature and vibrant red, yellow, and black coloration, this fish has become a favorite in the aquarium hobby – especially among planted tank hobbyists. Although hardy, these fish prefer well-oxygenated water with some current and will display their best colors when excellent water quality is maintained. The wild form from the streams and rivers of Karnataka state, India, is known for exhibiting vibrant, deep red coloration more pronounced than is typically displayed by tank raised specimens.
