Appearance and identification

Look for repeated scale marks rather than a continuous band. African banded barbs instead have narrow vertical bars.

Same-species behaviour

Groups encourage male displays but may not school tightly.

Space requirements

A 75 × 30 cm base (75 × 30 × 30 cm overall) with 6–10 of its own kind. Consider adult lanes, cover and water quality together.

Diet and feeding

Vary small prepared foods with suitable live or frozen prey.

Compatibility limits

Choose peaceful, similarly sized companions and watch competition.

Aquarium environment

Floating cover, roots and plants offer shelter and show the markings.
