The Roseline Shark, also known as the Red-Line Torpedo Barb or simply the Denison Barb (Sahyadria denisonii), is a striking and popular freshwater fish species often chosen for its vibrant colors and unique appearance. Here’s a comprehensive overview of the Roseline Shark:

Physical Characteristics:

1. Coloration: The Roseline Shark is renowned for its striking coloration. It features a silver body adorned with bright red or orange stripes running horizontally along its flanks. These red stripes give the fish its distinctive appearance, which is why it’s often referred to as the “Red-Line Torpedo Barb.”
2. Size: Adult Roseline Sharks can grow up to 6 inches (15 centimeters) in length, making them a substantial and eye-catching addition to a tank.
3. Body Shape: These fish have a torpedo-shaped body with a streamlined appearance, making them excellent swimmers.

Behavior and Care:

1. Tank Size: Roseline Sharks need a spacious tank due to their size and swimming behavior. A tank with a minimum capacity of 55 gallons (about 208 liters) is recommended.
2. Water Parameters: They thrive in slightly acidic to neutral water conditions. Aim for a pH range of 6.5 to 7.5 and a temperature range of 72-79°F (22-26°C).
3. Filtration and Water Quality: Effective filtration and regular water changes are crucial to maintaining high water quality. These fish require well-oxygenated water to thrive.
4. Diet: Roseline Sharks are omnivorous and accept a variety of foods. They enjoy high-quality flakes, pellets, live or frozen foods like bloodworms and brine shrimp, and vegetable-based foods like spirulina flakes.
5. Group Size: These fish are social and should be kept in small groups of at least three to minimize stress and encourage natural behaviors.
6. Tank Setup: Provide a well-decorated tank with plenty of swimming space and hiding spots using rocks, driftwood, and live plants. A sand or fine gravel substrate is ideal to prevent injury to their delicate barbels.

Tank Mates:

Roseline Sharks are generally peaceful but can be a bit territorial with their own kind. Suitable tankmates include other peaceful community fish species that are not overly aggressive or too small to be considered prey. Tetras, gouramis, peaceful barbs, and other non-aggressive species are good choices.

Breeding:

Breeding Roseline Sharks in captivity can be challenging due to the absence of detailed information about their breeding habits and requirements. Many Roseline Sharks available in the aquarium trade are wild-caught, and captive breeding is relatively rare.

Health and Disease:

These fish are generally hardy but can be susceptible to common aquarium diseases. Maintain stable water conditions, provide a balanced diet, and quarantine new additions to the tank to keep them healthy.

In summary, the Roseline Shark, also known as the Red-Line Torpedo Barb, is a captivating and colorful addition to a community aquarium. Their striking appearance and social nature make them a sought-after choice for aquarists who appreciate their unique beauty. By providing the right environment, tankmates, and care, you can enjoy the elegance and charm of Roseline Sharks in your aquarium.
