Compatibility
Betta × Endler's livebearer Compatibility
Compatibility calculated based on predation risk, behaviour profile, and water-parameter overlap.
Betta and Endler's livebearer can live together in a well-planted community tank, but territorial behaviour should be monitored and size difference should be monitored.

Envrionmental Factors
Temperature overlap
Betta: 24.0–30.0 °C
Endler's livebearer: 24.0–29.0 °C
Shared window: 24.0–29.0°C.
pH overlap
Betta: 6.0–7.5
Endler's livebearer: 7.0–8.5
Shared window: 7.0–7.5.
Hardness overlap
Betta: Very soft → Medium
Endler's livebearer: Medium → Hard
Shared hardness bands: 1 (overlap ratio 50%).
Flow match
Betta: Low
Endler's livebearer: Medium
Flow preferences do not conflict directly (no low-vs-high clash).
Behavioural Factors
Predation risk (size ratio)
Adult size ratio: 2.00x
Size gap is between 2.0x and 3.0x, so monitor for dominance and mouth-fit risk.
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.
