Natural Habitat & Origin
Cherry barbs are endemic to Sri Lanka, where they inhabit shaded, heavily vegetated streams and rivers. They are listed as vulnerable in the wild due to habitat loss, but captive-bred populations are thriving. Nearly all cherry barbs in the aquarium trade are captive bred.
Tank Setup
- Tank size: 10 gallons for 6, 20 gallons for 10–12
- Plants: Dense planting is essential — cherry barbs are shy and need cover to feel secure. Java moss, cryptocoryne, and vallisneria are excellent choices.
- Lighting: Subdued to moderate — mimics their shaded natural habitat and brings out the best red coloration in males
- Substrate: Dark sand or gravel enhances their colors
Water Parameters
- Temperature: 73–81°F (23–27°C)
- pH: 6.0–7.0 (slightly acidic preferred)
- GH: 4–10 dGH
Diet & Feeding
Easy to feed and accept all standard aquarium foods. A varied diet with frozen foods enhances the red coloration in males. Feed small amounts twice daily.
Breeding
Cherry barbs are egg scatterers that are relatively easy to breed. Males display intense red coloration and actively court females. They scatter adhesive eggs among fine-leaved plants or spawning mops. Remove adults after spawning as they will eat the eggs. Eggs hatch in 24–48 hours.
Tank Mates
One of the most peaceful barbs — compatible with virtually all gentle community fish. They are one of the few barb species safe to keep with bettas (in 10+ gallon tanks) and shrimp. Avoid keeping with aggressive or very large fish.
Frequently Asked Questions
Are cherry barbs fin nippers?
No. Unlike tiger barbs, cherry barbs are peaceful and do not nip fins. They are safe with bettas, guppies, and other long-finned fish.
Why isn't my cherry barb red?
Only males turn deep red, and even then it takes maturity (4–6 months) and good conditions. Females stay brownish-pink. Dark substrate, subdued lighting, a varied diet, and low stress all enhance male coloration.
