Banjo Catfish

Bunocephalus coracoideus

AnimaliaChordataActinopterygiiSiluriformesAspredinidae

📍 Amazon & Paraná Basins, South America

Ask Finn

Named for its flat, banjo-shaped body, this nocturnal catfish buries itself in sandy substrate during the day and emerges at night to scavenge. Nearly invisible when resting, it makes a fascinating oddball for peaceful community tanks.

Care Guide

Diet

Banjo catfish are carnivorous bottom feeders that prefer live or frozen foods such as bloodworms, brine shrimp, and small crustaceans. They will occasionally accept sinking pellets and tablet foods, but should be fed 3-4 times weekly with small portions. Supplement their diet with occasional vegetable matter like blanched zucchini to ensure balanced nutrition.

Behavior

These nocturnal, cryptic catfish spend most of their time buried in substrate or hiding among plants and décor, emerging primarily at dusk and night to forage. They are completely peaceful and solitary, showing no aggression toward tankmates but preferring to avoid interaction. Their camouflage behavior makes them fascinating to observe as they blend seamlessly with leaf litter and debris.

Breeding

Breeding Banjo catfish in captivity is extremely rare and poorly documented, with very few successful spawns recorded in the hobby. They require specific environmental triggers such as seasonal temperature drops and high water quality, making captive reproduction impractical for most aquarists. Virtually all specimens in the trade are wild-caught, and breeding information remains largely unknown.
