Relevant Information:

Similar looking to Nemadoras leporhinus but this species has longer leading fin rays and sports a clear dorsal with black markings at the base. Aquarium Care: For a large species it is non aggressive and can be kept with smaller species such as small characins, dwarf cichlids, small labyrinth species and also other small catfish such as Corydoras and the smaller members of the Loracariids. Provide a soft substrate such as fine sand as they like to sift through this for edibles and a sharp substrate could cause damage to its fine feathered barbels. Lone individuals will not do well in an aquarium setup so a group of three or more will be more beneficial to the long term health of this species. A planted aquarium is a must as they like to hide in the roots more so than having a rock or wood setup. Diet: Tablet foods, small live and frozen foods such as worms and Daphnia.
