Compatibility
Guppy × Freshwater Angelfish Compatibility
Compatibility calculated based on predation risk, behaviour profile, and water-parameter overlap.
Guppy and Freshwater Angelfish are not recommended together in most community setups, but territorial behaviour should be monitored and size difference should be monitored.

Envrionmental Factors
Temperature overlap
Guppy: 20.0–28.0 °C
Freshwater Angelfish: 24.0–30.0 °C
Shared window: 24.0–28.0°C.
pH overlap
Guppy: 7.0–8.0
Freshwater Angelfish: 6.8–7.8
Shared window: 7.0–7.8.
Hardness overlap
Guppy: Medium → Very hard
Freshwater Angelfish: Soft → Medium
Shared hardness bands: 1 (overlap ratio 50%).
Flow match
Guppy: Medium
Freshwater Angelfish: Medium
Flow preferences do not conflict directly (no low-vs-high clash).
Behavioural Factors
Predation risk (size ratio)
Adult size ratio: 2.40x
Size gap is between 2.0x and 3.0x, so monitor for dominance and mouth-fit risk.
Behaviour risk
- - Freshwater Angelfish: Territorial.
- - Freshwater Angelfish: Predatory.
- - Both species show territorial or semi-aggressive behaviour; conflicts are likely.
- - This pairing has a high risk of stress, chasing, or fin damage.
