Envrionmental Factors
Temperature overlap
Guppy: 20.0–28.0 °C
Platy: 20.0–25.0 °C
Shared window: 20.0–25.0°C.
pH overlap
Guppy: 7.0–8.0
Platy: 7.0–8.0
Shared window: 7.0–8.0.
Hardness overlap
Guppy: Medium → Very hard
Platy: Medium → Hard
Shared hardness bands: 2 (overlap ratio 100%).
Flow match
Guppy: Medium
Platy: Medium
Flow preferences do not conflict directly (no low-vs-high clash).
Behavioural Factors
Predation risk (size ratio)
Adult size ratio: 1.30x
Adult size gap is under 2.0x, which is usually a safer ratio.
Behaviour risk
- - Both species are generally peaceful; behaviour conflict risk is low.
