Appearance and identification

More intricately patterned across head and fins than the barred armoured bichir.

Same-species behaviour

Often nocturnal and scent-guided; calm behaviour does not rule out predation.

Space requirements

Plan broad adult floor space (180 × 60 cm), escape prevention and surface breathing access.

Diet and feeding

Offer suitable meaty foods; assess dry-food acceptance individually.

Compatibility limits

Mouth-sized companions remain prey.

Aquarium environment

Use soft substrate, smooth retreats and clear routes.
