Compatibility
Celestial Pearl Danio × X-Ray Tetra Compatibility
Compatibility calculated based on predation risk, behaviour profile, and water-parameter overlap.
Celestial Pearl Danio and X-Ray Tetra can live together in a well-planted community tank, but size difference should be monitored and water-parameter overlap should be checked carefully.

Envrionmental Factors
Temperature overlap
Celestial Pearl Danio: 15.0–24.0 °C
X-Ray Tetra: 24.0–28.0 °C
Shared window: 24.0–24.0°C.
pH overlap
Celestial Pearl Danio: 7.0–8.0
X-Ray Tetra: 6.0–8.0
Shared window: 7.0–8.0.
Hardness overlap
Celestial Pearl Danio: Medium → Hard
X-Ray Tetra: Soft → Medium
Shared hardness bands: 1 (overlap ratio 50%).
Flow match
Celestial Pearl Danio: Low
X-Ray Tetra: Medium
Flow preferences do not conflict directly (no low-vs-high clash).
Behavioural Factors
Predation risk (size ratio)
Adult size ratio: 2.38x
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.
