Compatibility
Zebra danio × Discus Compatibility
Compatibility calculated based on predation risk, behaviour profile, and water-parameter overlap.
Zebra danio and Discus are not recommended together in most community setups, but size difference should be monitored and water-parameter overlap should be checked carefully.

Envrionmental Factors
Temperature overlap
Zebra danio: 15.0–24.0 °C
Discus: 27.0–30.0 °C
No shared operating range is present between the recorded values.
pH overlap
Zebra danio: 6.0–8.0
Discus: 6.0–6.5
Shared window: 6.0–6.5.
Hardness overlap
Zebra danio: Soft → Hard
Discus: Very soft → Soft
Shared hardness bands: 1 (overlap ratio 50%).
Flow match
Zebra danio: Medium
Discus: Low
Flow preferences do not conflict directly (no low-vs-high clash).
Behavioural Factors
Predation risk (size ratio)
Adult size ratio: 3.40x
Size gap is above 3.0x, which can increase predation pressure.
Behaviour risk
- - Discus: Hierarchical.
- - Both species are generally peaceful; behaviour conflict risk is low.
