In nature the Banjo Catfish can be found buried, sometimes several inches deep, in the leaf litter commonly found at the bottom of forest streams.

Breeding is possible, the species spawns in groups. Mature females are larger and deeper bodied than males. It is mature when it is 12 cm long. Spawning can be initiated with lowering the water level and a reduction in water temperature to 20-22°C. 4000-5000 eggs are laid on the sandy bottom, usually in more than one spawning. Plants may be inadvertantly uprooted during spawning. Water in the aquarium can be as much as 30 cm deep. The parents guard the young until they hatch. The fry should be fed with live food, such as Rotifers then, as they grow, tubifex worms. They will not accept flakes. They do not feed on daphnia.
