Envrionmental Factors
Temperature overlap
Dwarf Rasbora: 24.0–26.0 °C
Cherry barb: 22.0–27.0 °C
Shared window: 24.0–26.0°C.
pH overlap
Dwarf Rasbora: 5.0–6.0
Cherry barb: -
One or both species are missing range data for this check.
Hardness overlap
Dwarf Rasbora: Very soft → Soft
Cherry barb: Soft → Medium
Shared hardness bands: 1 (overlap ratio 50%).
Flow match
Dwarf Rasbora: Low
Cherry 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
- - Both species are generally peaceful; behaviour conflict risk is low.
