Guppy and Dwarf Gourami can live together in a well-planted community tank, but territorial behaviour should be monitored and water-parameter overlap should be checked carefully.

Envrionmental Factors

Temperature overlap
Guppy: 20.0–28.0 °C
Dwarf Gourami: 18.0–28.0 °C
Shared window: 20.0–28.0°C.
pH overlap
Guppy: 7.0–8.0
Dwarf Gourami: 6.0–7.5
Shared window: 7.0–7.5.
Hardness overlap
Guppy: Medium → Very hard
Dwarf Gourami: Very soft → Medium
Shared hardness bands: 1 (overlap ratio 33%).
Flow match
Guppy: Medium
Dwarf Gourami: Low
Flow preferences do not conflict directly (no low-vs-high clash).

Behavioural Factors

Predation risk (size ratio)
Adult size ratio: 1.60x
Adult size gap is under 2.0x, which is usually a safer ratio.
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.
