Appearance and identification

Usually more vertically barred than the plain Senegal bichir, but captive-bred markings can be weak; stripes alone do not identify it.

Same-species behaviour

Often nocturnal and scent-guided; quiet behaviour does not make companions safe.

Space requirements

Provide a secure lid, surface breathing access, soft substrate and cover; prioritise floor area. A 120 × 45 cm base for adult planning.

Diet and feeding

Offer appropriate animal foods; newly acquired fish may refuse dry feed.

Compatibility limits

Keep surfacing and bottom routes open. Plants do not prevent predation on small fish or shrimp.
