Compatibility
Platy × Bristlenose Catfish Compatibility
Compatibility calculated based on predation risk, behaviour profile, and water-parameter overlap.
Platy and Bristlenose Catfish can usually live together in a well-planted community tank, but size difference should be monitored.

Envrionmental Factors
Temperature overlap
Platy: 20.0–25.0 °C
Bristlenose Catfish: 23.0–27.0 °C
Shared window: 23.0–25.0°C.
pH overlap
Platy: 7.0–8.0
Bristlenose Catfish: 5.5–8.0
Shared window: 7.0–8.0.
Hardness overlap
Platy: Medium → Hard
Bristlenose Catfish: Soft → Hard
Shared hardness bands: 2 (overlap ratio 100%).
Flow match
Platy: Medium
Bristlenose Catfish: Medium
Flow preferences do not conflict directly (no low-vs-high clash).
Behavioural Factors
Predation risk (size ratio)
Adult size ratio: 2.31x
Size gap is between 2.0x and 3.0x, so monitor for dominance and mouth-fit risk.
Behaviour risk
- - Both species are generally peaceful; behaviour conflict risk is low.
