Rosy Barb Temperature: Ideal Water Temp
Ideal: 64-77°F (18-25°C)
The Rosy Barb is a coldwater / subtropical species. Aim for the middle of its range, around 71°F, and keep it steady — sudden swings stress fish more than a stable temperature.
This species tolerates cooler water, so it can often be kept without a heater in a room near 64-77°F, though a heater still improves stability.
