How to care Roseline Shark
The Roseline Shark (Sahyadria denisonii), also known as the Denison barb or Red-line torpedo, is a popular freshwater species native to the rivers and streams of India. Despite its name, it is not a true shark but a member of the Cyprinidae family. The Roseline Shark is known for its striking coloration, which includes a bright red horizontal stripe running across its body, making it one of the most visually captivating species in the aquarium hobby. The males tend to have more intense coloration, especially during the breeding season.
In the wild, Roseline Sharks are found in fast-moving streams and rivers in the Western Ghats region of India. They thrive in cool, oxygen-rich water with a neutral to slightly acidic pH. In an aquarium, they require a tank with good water flow, and they appreciate a well-planted environment with open swimming spaces. A minimum tank size of 30 gallons (114 liters) is recommended to accommodate their active swimming behavior. They do best in a well-maintained tank with stable water conditions.
As omnivores, Roseline Sharks thrive on a varied diet that includes high-quality pellets, flakes, and live or frozen foods such as bloodworms, brine shrimp, and daphnia. They are also known to eat algae, so a well-balanced diet should include both plant and animal matter. A regular feeding schedule is essential, and it is important to avoid overfeeding as these fish are prone to obesity.
The Roseline Shark is generally peaceful but can be territorial, particularly if kept in a small space. It is best to keep them in groups of at least six individuals to help reduce any potential aggression, especially among males. While they are typically peaceful, they may exhibit mild aggression toward other fish with similar body shapes or colors. They are compatible with other peaceful community fish, such as tetras and danios.
Maintaining proper water conditions is vital for the Roseline Shark’s health. They thrive in temperatures between 72°F and 78°F (22-26°C), with a pH between 6.5 and 7.5. Water hardness should be kept between 5-12 dGH, and regular water changes should be conducted to maintain water quality. These fish are sensitive to poor water conditions, so a good filtration system is essential.

With its striking colors, peaceful temperament, and relatively easy care requirements, it can make an excellent choice for both beginner and experienced aquarists.
