Water Parameters

Parameter	Ideal Range
Temperature	22–28 °C (72–82 °F)
pH	6.0–7.5
Hardness	Soft to medium (up to ~12–15 dGH)
Flow	Gentle to moderate

Stable, clean water is more important than chasing exact numbers.

Tank Setup

• Minimum tank: 20 gal (larger strongly recommended)
• Group size: 6+ (shoaling species)
• Substrate: Fine sand (critical to protect barbels)
• Décor: Driftwood, leaf litter, smooth rocks, shaded areas
• Lighting: Medium–low (enhances green coloration)

Corydoras regularly surface to gulp air—this is normal behavior.
