Pethia conchonius
A medium barb whose males turn from silver to deep claret in breeding condition. Among the hardiest of the small cyprinids, it tolerates cool water and colours best in a group of eight or more as the males compete.
Pethia conchonius ranges from Afghanistan through Pakistan, India, Nepal and Bangladesh. FishBase records a maximum of 14cm TL, pH 6.0-8.0, 5-19 dH and 18-22C, and places it in lakes and fast-flowing hill streams. Seriously Fish gives 100mm SL, 16-24C, pH 6.0-8.0, 5-20 dGH and a 100 x 30cm base of about 90 litres. It is regarded as one of the hardiest barbs: normally silver, the male flushes deep claret in breeding condition while the slightly larger female becomes more luminous. Ornamental strains include long-finned, veil-tail, super red, neon and golden forms. Subtropical and tolerant of cool water, it shows best in a group of eight to ten as the males compete for attention. The IUCN rates it Least Concern and it is not listed by CITES.

Seriously Fish suggests a 100 x 30cm base of about 90 litres. Colour is best over a dark substrate in a heavily planted tank, with floating plants and driftwood to soften the light. Strong filtration is unnecessary, but it appreciates some flow.
Seriously Fish gives 16-24C, pH 6.0-8.0 and 5-20 dGH, while FishBase records 18-22C, pH 6.0-8.0 and 5-19 dH. It is undemanding about chemistry but, being subtropical, is not suited to year-round warmth.
Peaceful and easy to mix with small cyprinids, characins, livebearers, rainbowfish, anabantoids, catfish and loaches. Seriously Fish recommends at least eight to ten, which makes the fish far less nervous.
An omnivore taking worms, crustaceans and insects. Dried food serves as the staple, and frozen bloodworm or Artemia deepens the claret of breeding males.
An egg scatterer with no parental care. Mature males are slimmer and deep claret while females are larger and thicker-bodied, so sexing is easy. Spawn them in a dimly lit separate tank over mesh or fine-leaved plants and remove the adults afterwards.
Among the hardiest small cyprinids and a good beginner's fish. Hybrids with congeners have been produced but their offspring are reported to be infertile. It reaches 14cm, so it is not suited to long-term life in a small tank. The IUCN rates it Least Concern and it is not listed by CITES.
Beginner. This is a beginner-friendly species. No special equipment or experience is required, and it can be kept successfully with basic care setup.
The ideal temperature for Rosy Barb is 16〜24℃. Avoid sudden temperature changes and maintain a stable environment.
The average lifespan of Rosy Barb is 5-8 years. With proper care and nutrition, they can live a long and healthy life.
Rosy Barb typically reaches Up to 14cm TL as an adult. Size may vary depending on care conditions and individual genetics.
Rosy Barb feeds on: Dried, frozen and live foods. Aim for a balanced diet with appropriate feeding frequency.
