Behavioural Factors
Predation risk (size ratio)
Adult size ratio: 1.60x
Adult size gap is under 2.0x, which is usually a safer ratio.
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.
