The removal of Pseudobunocephalus from Bunocephalus was an attempt to make it monophyletic.[1] Even in this reduced state, Bunocephalus is still the largest genus in the Aspredinidae.[1]
In the aquarium
B. coracoideus is the most common species of banjo catfish found in the aquariumfishkeepinghobby.[3][4] These fish are nocturnal.[5] This species is peaceful and a good idea for a community aquarium.[4] These fish may be kept with sand to allow them to bury themselves or with a flat rock to hide underneath.[4] Reproduction has been accomplished in the home aquarium. These fish can be easily sexed because females are much fatter and fuller than males. The mating pair should be conditioned on live foods for at least a month.[5] Spawning is induced by a larger water change; the pair will spawn within two days.[5] Spawning occurs at night.[4] Some sources say they spawn under a fallen leaf or on a large rock, incubating their eggs by sitting on them, while others list them as egg-scatterers.[4][5]
