Delhezi Bichir

The Delhezi Bichir, also called the Banded Bichir, has bold dark bars over a gray-to-olive body and a distinctive row of dorsal finlets. Native to the Congo basin, it is a medium-sized bichir with a sturdy build and an unhurried, bottom-oriented way of exploring its surroundings.

Aquarium setup

A broad aquarium with fine sand, smooth shelters, and open bottom space suits this species. Add driftwood or sturdy plants for shade without blocking swimming routes. Good filtration and regular water changes are essential, while sheltered resting spots should remain out of strong direct current.

Bichirs breathe atmospheric air. Keep the surface accessible, leave an air gap beneath the cover, and secure the lid and all cable or pipe openings to prevent escapes.

Diet and feeding

Provide a varied selection of earthworms, thawed shrimp, mussel, and other appropriately sized aquatic foods. Sinking carnivore pellets can also be offered if accepted. Place food where the bichir can find it, especially in the evening, and check that quicker tankmates do not consume everything first.

Compatibility

Predatory rather than constantly aggressive, the Delhezi can share a roomy aquarium with suitable fish that are too large to fit in its mouth. Avoid small fish, shrimp, aggressive fin nippers, and large size differences between bichirs. Individual temperament and feeding competition still require observation.
