Zebra danio and Freshwater Angelfish are not recommended together in most community setups, but territorial behaviour should be monitored, size difference should be monitored, and water-parameter overlap should be checked carefully.

Envrionmental Factors

Temperature overlap
Zebra danio: 15.0–24.0 °C
Freshwater Angelfish: 24.0–30.0 °C
Shared window: 24.0–24.0°C.
pH overlap
Zebra danio: 6.0–8.0
Freshwater Angelfish: 6.8–7.8
Shared window: 6.8–7.8.
Hardness overlap
Zebra danio: Soft → Hard
Freshwater Angelfish: Soft → Medium
Shared hardness bands: 2 (overlap ratio 100%).
Flow match
Zebra danio: 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.
