Envrionmental Factors
Temperature overlap
Neon tetra: 20.0–26.0 °C
Corydoras: 22.0–25.0 °C
Shared window: 22.0–25.0°C.
pH overlap
Neon tetra: 5.5–7.5
Corydoras: 6.0–7.0
Shared window: 6.0–7.0.
Hardness overlap
Neon tetra: Very soft → Medium
Corydoras: Soft → Hard
Shared hardness bands: 2 (overlap ratio 67%).
Flow match
Neon tetra: Low
Corydoras: Medium
Flow preferences do not conflict directly (no low-vs-high clash).
Behavioural Factors
Predation risk (size ratio)
Adult size ratio: 1.75x
Adult size gap is under 2.0x, which is usually a safer ratio.
Behaviour risk
- - Both species are generally peaceful; behaviour conflict risk is low.
