Compatibility
Neon tetra × Tiger Barb Compatibility
Compatibility calculated based on predation risk, behaviour profile, and water-parameter overlap.
Neon tetra and Tiger Barb 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
Tiger Barb: 21.0–26.0 °C
Shared window: 21.0–26.0°C.
pH overlap
Neon tetra: 5.5–7.5
Tiger Barb: 6.5–7.5
Shared window: 6.5–7.5.
Hardness overlap
Neon tetra: Very soft → Medium
Tiger Barb: Soft → Hard
Shared hardness bands: 2 (overlap ratio 67%).
Flow match
Neon tetra: Low
Tiger Barb: Medium
Flow preferences do not conflict directly (no low-vs-high clash).
Behavioural Factors
Predation risk (size ratio)
Adult size ratio: 2.00x
Size gap is between 2.0x and 3.0x, so monitor for dominance and mouth-fit risk.
Behaviour risk
- - Tiger Barb: Fin Nipper.
- - Tiger Barb: Hierarchical.
- - Both species show territorial or semi-aggressive behaviour; conflicts are likely.
- - This pairing has a high risk of stress, chasing, or fin damage.
