Envrionmental Factors
Temperature overlap
Ember Tetra: 24.0–28.0 °C
Cardinal Tetra: 23.0–27.0 °C
Shared window: 24.0–27.0°C.
pH overlap
Ember Tetra: 6.0–7.0
Cardinal Tetra: 5.0–7.0
Shared window: 6.0–7.0.
Hardness overlap
Ember Tetra: Very soft → Soft
Cardinal Tetra: Very soft → Soft
Shared hardness bands: 2 (overlap ratio 100%).
Flow match
Ember Tetra: Medium
Cardinal Tetra: Low
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.
