Compatibility
Ember Tetra × Freshwater Angelfish Compatibility
Compatibility calculated based on predation risk, behaviour profile, and water-parameter overlap.
Ember Tetra and Freshwater Angelfish are not recommended together in most community setups, but territorial behaviour should be monitored, size difference should be monitored, and water-parameter overlap should be checked carefully.

Envrionmental Factors
Temperature overlap
Ember Tetra: 24.0–28.0 °C
Freshwater Angelfish: 24.0–30.0 °C
Shared window: 24.0–28.0°C.
pH overlap
Ember Tetra: 6.0–7.0
Freshwater Angelfish: 6.8–7.8
Shared window: 6.8–7.0.
Hardness overlap
Ember Tetra: Very soft → Soft
Freshwater Angelfish: Soft → Medium
Shared hardness bands: 1 (overlap ratio 50%).
Flow match
Ember Tetra: Medium
Freshwater Angelfish: Medium
Flow preferences do not conflict directly (no low-vs-high clash).
Behavioural Factors
Predation risk (size ratio)
Adult size ratio: 6.00x
Size gap is above 3.0x, which can increase predation pressure.
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.
