The Rose Line Barb (Pethia conchonius) is a captivating and lively freshwater species renowned for its rosy hue and graceful movements. Native to slow-moving rivers and ponds across India, Bangladesh, and Nepal, this species has become a staple for aquarists worldwide due to its hardiness, adaptability, and peaceful nature.

🌿 Appearance & Behavior

The Rose Line Barb features a metallic pink to red body with subtle silver undertones and a distinct black spot near the tail. Males often display a more intense coloration, especially during breeding periods. They are active swimmers and should be kept in groups of at least 5–6 individuals, which encourages natural schooling behavior and reduces stress.

🏡 Tank Setup & Environment

Provide a 30-gallon or larger aquarium with ample swimming space, live plants, and gentle filtration. The inclusion of driftwood, rocks, and subdued lighting helps mimic their natural habitat. A tight-fitting lid is recommended, as barbs are known jumpers.

🍽️ Feeding

Rose Line Barbs are omnivorous, accepting a wide range of foods including high-quality flakes, micro pellets, bloodworms, brine shrimp, and blanched vegetables. Feeding a varied diet ensures optimal coloration and health.

💧 Water Parameters

Maintain stable conditions with a temperature range of 22–28°C (72–82°F), pH 6.5–7.5, and moderate hardness. Perform weekly water changes (20–25%) to keep the environment clean and stress-free.

🤝 Tank Mates & Compatibility

This species thrives in peaceful community aquariums. Suitable tank mates include Tetras, Rasboras, Corydoras Catfish, Gouramis, and other small barbs. Avoid aggressive or fin-nipping species.

🧬 Breeding Information

When breeding, males display deeper red coloration. Provide a separate breeding tank with fine-leaved plants for egg scattering. The adults should be removed after spawning to prevent egg predation.
