Compatibility
Three Spot Gourami × Discus Compatibility
Compatibility calculated based on predation risk, behaviour profile, and water-parameter overlap.
Three Spot Gourami and Discus can live together in a well-planted community tank, but territorial behaviour should be monitored.

Envrionmental Factors
Temperature overlap
Three Spot Gourami: 23.0–30.0 °C
Discus: 27.0–30.0 °C
Shared window: 27.0–30.0°C.
pH overlap
Three Spot Gourami: 6.0–8.0
Discus: 6.0–6.5
Shared window: 6.0–6.5.
Hardness overlap
Three Spot Gourami: Soft → Hard
Discus: Very soft → Soft
Shared hardness bands: 1 (overlap ratio 50%).
Flow match
Three Spot Gourami: Low
Discus: Low
Flow preferences do not conflict directly (no low-vs-high clash).
Behavioural Factors
Predation risk (size ratio)
Adult size ratio: 1.13x
Adult size gap is under 2.0x, which is usually a safer ratio.
Behaviour risk
- - Three Spot Gourami: Territorial.
- - Discus: Hierarchical.
- - At least one species can be pushy or fin-nippy; monitor closely.
- - Behaviour may vary by tank size and stocking; have a backup plan.
