Compatibility
Neon tetra × Freshwater Angelfish Compatibility
Compatibility calculated based on predation risk, behaviour profile, and water-parameter overlap.
Neon tetra 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
Neon tetra: 20.0–26.0 °C
Freshwater Angelfish: 24.0–30.0 °C
Shared window: 24.0–26.0°C.
pH overlap
Neon tetra: 5.5–7.5
Freshwater Angelfish: 6.8–7.8
Shared window: 6.8–7.5.
Hardness overlap
Neon tetra: Very soft → Medium
Freshwater Angelfish: Soft → Medium
Shared hardness bands: 2 (overlap ratio 100%).
Flow match
Neon tetra: Low
Freshwater Angelfish: Medium
Flow preferences do not conflict directly (no low-vs-high clash).
Behavioural Factors
Predation risk (size ratio)
Adult size ratio: 3.00x
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.
