Compatibility
Betta × Zebra danio Compatibility
Compatibility calculated based on predation risk, behaviour profile, and water-parameter overlap.


Betta and Zebra danio 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
Betta: 24.0–30.0 °C
Zebra danio: 15.0–24.0 °C
Shared window: 24.0–24.0°C.
pH overlap
Betta: 6.0–7.5
Zebra danio: 6.0–8.0
Shared window: 6.0–7.5.
Hardness overlap
Betta: Very soft → Medium
Zebra danio: Soft → Hard
Shared hardness bands: 2 (overlap ratio 67%).
Flow match
Betta: Low
Zebra danio: Medium
Flow preferences do not conflict directly (no low-vs-high clash).
Behavioural Factors
Predation risk (size ratio)
Adult size ratio: 1.20x
Adult size gap is under 2.0x, which is usually a safer ratio.
Behaviour risk
- - Betta: Territorial.
- - At least one species can be pushy or fin-nippy; monitor closely.
- - Behaviour may vary by tank size and stocking; have a backup plan.
