Dysichthys Banjo Catfish

Dysichthys coracoideus is a robust aspredinid whose particularly wide, depressed head makes it one of the most dramatically built banjo catfish available in the hobby. Found across lowland river systems of the Amazon basin, it inhabits shallow sandy or silty margins in slow water, exploiting its extreme flattening and textured skin to remain invisible on the substrate. It is the broadest-headed of the commonly available aspredinids.

In the aquarium, Dysichthys coracoideus follows the same habits as Bunocephalus — burying by day, foraging at night. Its somewhat larger body size means it benefits from slightly more space, and its broader head allows it to swallow larger prey items than its slender relatives. It will eat appropriately sized worms, small invertebrates, and sinking pellets.

This species is peaceful and entirely harmless to appropriately sized tankmates. Like all banjo catfish, it demands a deep, fine sand substrate for burying and will stress without it. Dim lighting, leaf litter, and the absence of aggressive food competitors will keep it in optimal condition. Its extraordinary morphology makes it a perennial favourite for oddball catfish enthusiasts.

Water: 20–27°C, pH 5.5–7.5, soft to moderately hard (GH 2–15). Tank: 100 L minimum; deep fine sand essential; leaf litter; very low lighting; slow-moving water. Feeding: Sinking pellets, frozen bloodworm, earthworm sections, tubifex; nocturnal target feeding. Breeding: Presumed similar to other aspredinids; rarely bred in captivity. Compatibility: Peaceful; compatible with community fish that won't steal food from the substrate.
