Compatibility
Dwarf Gourami × Cardinal Tetra Compatibility
Compatibility calculated based on predation risk, behaviour profile, and water-parameter overlap.


Dwarf Gourami and Cardinal Tetra 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
Dwarf Gourami: 18.0–28.0 °C
Cardinal Tetra: 23.0–27.0 °C
Shared window: 23.0–27.0°C.
pH overlap
Dwarf Gourami: 6.0–7.5
Cardinal Tetra: 5.0–7.0
Shared window: 6.0–7.0.
Hardness overlap
Dwarf Gourami: Very soft → Medium
Cardinal Tetra: Very soft → Soft
Shared hardness bands: 2 (overlap ratio 100%).
Flow match
Dwarf Gourami: Low
Cardinal Tetra: Low
Flow preferences do not conflict directly (no low-vs-high clash).
Behavioural Factors
Predation risk (size ratio)
Adult size ratio: 2.29x
Size gap is between 2.0x and 3.0x, so monitor for dominance and mouth-fit risk.
Behaviour risk
- - Dwarf Gourami: 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.
