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


Betta and Tiger Barb are not recommended together in most community setups, but territorial behaviour should be monitored.

Envrionmental Factors
Temperature overlap
Betta: 24.0–30.0 °C
Tiger Barb: 21.0–26.0 °C
Shared window: 24.0–26.0°C.
pH overlap
Betta: 6.0–7.5
Tiger Barb: 6.5–7.5
Shared window: 6.5–7.5.
Hardness overlap
Betta: Very soft → Medium
Tiger Barb: Soft → Hard
Shared hardness bands: 2 (overlap ratio 67%).
Flow match
Betta: Low
Tiger Barb: Medium
Flow preferences do not conflict directly (no low-vs-high clash).
Behavioural Factors
Predation risk (size ratio)
Adult size ratio: 1.33x
Adult size gap is under 2.0x, which is usually a safer ratio.
Behaviour risk
- - Betta: Territorial.
- - Tiger Barb: Fin Nipper.
- - Tiger Barb: Hierarchical.
- - Both species show territorial or semi-aggressive behaviour; conflicts are likely.
