The Torpedo Roseline Barb, also known as the Denison Barb, is a stunning freshwater fish native to fast-flowing streams and rivers in India. It's famous for its torpedo-shaped body and vibrant red and black markings, making it a popular choice for aquarium enthusiasts.

Tank Size:

• Minimum Tank Size: 208 litres
• Ideal Tank Size: 284 litres or larger
  • The Torpedo Roseline Barb is an active swimmer and prefers to live in groups. A spacious tank is crucial to provide enough room for them to swim and exhibit natural behaviours.

Water Parameters:

• Temperature: 22°C to 26°C
• pH Level: 6.5 to 8.0
• Water Hardness: 5 to 15 dGH
• Filtration & Flow: Moderate to strong water flow, mimicking their natural fast-flowing stream environment. A quality external filter is recommended to maintain clean water, as they are sensitive to poor water conditions.

Tank Setup:

• Substrate: Sand or fine gravel substrate to mimic their natural riverbed habitat.
• Decoration: Include rocks, driftwood, and live plants to create hiding spots and add natural décor. However, keep open spaces for swimming.
• Lighting: Moderate lighting is ideal. Too much light may cause stress.
• Cover: Torpedo Barbs are known to jump, so a secure tank lid is essential.

Tank Mates:

• Compatibility: Peaceful, but very active fish. They do best in a community tank with other fast-moving, non-aggressive species.
• Good tank mates include:
  • Rainbowfish
  • Larger Tetras (e.g., Congo Tetras)
  • Danios
  • Peaceful Barbs (not aggressive varieties)
  • Corydoras Catfish
• Avoid: Slow-moving fish or fish with long fins (like Bettas), as the Torpedo Roseline Barb may stress them out by constantly swimming around.

Diet:

• Type of Diet: Omnivorous
• Food Options:
  • High-quality flake or pellet food as a staple
  • Frozen or live foods such as bloodworms, brine shrimp, and daphnia
  • Occasional plant matter like spirulina-based foods or blanched vegetables (e.g., zucchini or spinach)
• Feeding Frequency: 2-3 times per day in small portions

Behavior and Temperament:

• Schooling Fish: They should be kept in groups of at least 5-6 to feel secure and reduce stress.
• Active Swimmers: They are constantly on the move, so a long tank is preferable over a tall tank to allow for horizontal swimming.

Breeding:

• Breeding in Captivity: Breeding in home aquariums is rare and challenging. It is believed that commercial breeding is often done using hormones.
• Sexual Dimorphism: Males tend to be slimmer and more vibrant than females, but it's difficult to distinguish between the sexes unless the fish are fully mature.

Common Health Issues:

• Ich (White Spot Disease): Like many freshwater fish, the Torpedo Roseline Barb can be susceptible to Ich if water quality is poor or they experience stress.
• Fin Rot or Bacterial Infections: Good water maintenance will help prevent these issues.
• Sensitive to Poor Water Quality: These fish need clean, well-oxygenated water. Regular water changes (about 25% weekly) are essential.

Lifespan:

• Average Lifespan: 5 to 7 years, though they can live longer with optimal care.

Final Tips:

• Tank Maintenance: Regular water changes and monitoring of water parameters are crucial to keeping these sensitive fish healthy.
• Acclimation: When introducing them to the aquarium, acclimate them slowly to avoid shock due to temperature or pH differences.

The Torpedo Roseline Barb is a striking and active fish that adds a splash of color and energy to any community tank, but they require a well-maintained environment to thrive.
