Compatibility
Corydoras × Freshwater Angelfish Compatibility
Compatibility calculated based on predation risk, behaviour profile, and water-parameter overlap.
Corydoras and Freshwater Angelfish can live together in a well-planted community tank, but territorial behaviour should be monitored and water-parameter overlap should be checked carefully.

Envrionmental Factors
Temperature overlap
Corydoras: 22.0–25.0 °C
Freshwater Angelfish: 24.0–30.0 °C
Shared window: 24.0–25.0°C.
pH overlap
Corydoras: 6.0–7.0
Freshwater Angelfish: 6.8–7.8
Shared window: 6.8–7.0.
Hardness overlap
Corydoras: Soft → Hard
Freshwater Angelfish: Soft → Medium
Shared hardness bands: 2 (overlap ratio 100%).
Flow match
Corydoras: Medium
Freshwater Angelfish: Medium
Flow preferences do not conflict directly (no low-vs-high clash).
Behavioural Factors
Predation risk (size ratio)
Adult size ratio: 1.71x
Adult size gap is under 2.0x, which is usually a safer ratio.
Behaviour risk
- - Freshwater Angelfish: Territorial.
- - Freshwater Angelfish: Predatory.
- - At least one species can be pushy or fin-nippy; monitor closely.
- - Behaviour may vary by tank size and stocking; have a backup plan.
