The Rosy Barb (Pethia conchonius) is a stunning freshwater species known for its vibrant pinkish-red body and playful nature. Native to the calm, vegetated rivers of South Asia, this fish adds both beauty and activity to your aquarium.

Rosy Barbs are among the most hardy and adaptable tropical fish, making them a perfect choice for beginners looking to start a peaceful community tank.

🐟 Appearance and Behavior

Males display a deeper rosy-red coloration, especially during breeding season, while females tend to be more golden or silver. They are active swimmers and prefer to live in groups of five or more, which helps reduce stress and encourages natural schooling behavior.

They are peaceful but can nip fins if kept in too small groups, so maintaining a small school is highly recommended.

🏡 Tank Setup

Provide a minimum of 75 litres (20 gallons) for a small group. A well-planted aquarium with open swimming areas is ideal. Use a gentle filter and moderate lighting. Floating plants help diffuse light and offer cover.

Maintain stable water parameters:

• Temperature: 22–28°C (72–82°F)

• pH: 6.0–7.5

• Hardness: 5–19 dGH

Regular water changes and good filtration will keep your Rosy Barbs healthy and vibrant.

🍽️ Diet

Rosy Barbs are omnivorous and thrive on a varied diet of high-quality flakes, pellets, frozen bloodworms, and brine shrimp. Occasional vegetable-based foods (like blanched spinach or peas) help enhance their coloration and digestion.

💡 Care Level and Compatibility

These fish are easy to care for, adaptable, and tolerant of a wide range of water conditions. They do well with other peaceful community fish like Tetras, Danios, Corydoras, and Gouramis.

Avoid pairing them with long-finned or slow-moving species (like Angelfish or Bettas), as they may occasionally nip fins.

🌼 Breeding Information

Rosy Barbs are egg scatterers. Provide a separate breeding tank with fine plants or a spawning mop. After spawning, remove adults to prevent them from eating the eggs. Fry hatch in 24–36 hours and can be fed infusoria or crushed flakes.
