Rosy Barb

The Rosy Barb (Pethia conchonius) is a freshwater schooling fish valued for a robust body and warm pink-red coloration, with males turning intensely red in breeding condition. Native to South Asia, this species is popular in planted community aquariums because it combines visual impact with manageable care requirements. Its size and color presence make it a centerpiece school for bigger planted communities.

Appearance and Coloration

Rosy Barb is known for clean pattern definition and color response that improves under stable water quality, varied feeding, and proper group size. In mature planted aquariums, the body pattern reads clearly even during fast schooling movement.

Size and Lifespan

• Adult size: 14 cm (5.5 inches)
• Typical lifespan: 5-7 years with stable parameters and quality diet
• 
  

Ideal Aquarium Setup

This species performs best in a biologically mature aquarium that prioritizes oxygenation and stable chemistry.

• Tank size: 30-40 gallons (115-150 L)
• Temperature: 18-22 C (64-72 F)
• pH: 6.5-7.5
• Aquascape direction: larger planted layouts with open lanes, wood, and tougher plant species
• 
  

Behavior and Temperament

Rosy Barb is a robust and active schooling barb suited to larger peaceful communities. Keep groups of at least 6-8+ individuals so hierarchy and movement are distributed naturally. Good companion options include larger tetras, rainbowfish, corydoras, and medium peaceful barbs.

Diet and Feeding

Rosy Barb is classified here as Omnivore. Build a varied schedule with high-quality staple foods, plus frozen or live options several times per week. A rotating diet supports immunity, activity, and stronger display color.

Breeding Notes

Most cyprinids in this group are egg scatterers. Conditioning with diverse foods and offering fine-leaved plants or spawning media can improve egg survival. If breeding is the goal, move adults after spawning to reduce egg predation.

Why Keep Rosy Barb in a Planted Aquarium?

Rosy Barb provides movement, contrast, and schooling structure that helps a layout feel alive without overpowering the design. For aquascaping-focused community tanks, it is a practical and visually rewarding choice.
