Appearance and identification

Natural adults are plainer than the vertically barred armoured bichir.

Same-species behaviour

Surfaces to breathe. Quiet behaviour does not make small companions safe.

Space requirements

Fit a secure lid while retaining surface access for air breathing. Prioritize floor area and refuges. Plan a 150 × 60 cm base for an adult.

Diet and feeding

Offer suitable meaty foods; pellet acceptance varies.

Aquarium environment

Use soft substrate and stable cover. Keep surfacing routes open.
