Compatibility
Three Spot Gourami × Freshwater Angelfish Compatibility
Compatibility calculated based on predation risk, behaviour profile, and water-parameter overlap.
Three Spot Gourami and Freshwater Angelfish are not recommended together in most community setups, but territorial behaviour should be monitored.

Envrionmental Factors
Temperature overlap
Three Spot Gourami: 23.0–30.0 °C
Freshwater Angelfish: 24.0–30.0 °C
Shared window: 24.0–30.0°C.
pH overlap
Three Spot Gourami: 6.0–8.0
Freshwater Angelfish: 6.8–7.8
Shared window: 6.8–7.8.
Hardness overlap
Three Spot Gourami: Soft → Hard
Freshwater Angelfish: Soft → Medium
Shared hardness bands: 2 (overlap ratio 100%).
Flow match
Three Spot Gourami: Low
Freshwater Angelfish: Medium
Flow preferences do not conflict directly (no low-vs-high clash).
Behavioural Factors
Predation risk (size ratio)
Adult size ratio: 1.25x
Adult size gap is under 2.0x, which is usually a safer ratio.
Behaviour risk
- - Three Spot Gourami: Territorial.
- - Freshwater Angelfish: Territorial.
- - Freshwater Angelfish: Predatory.
- - Both species show territorial or semi-aggressive behaviour; conflicts are likely.
