Banjo catfish, Bunocephalus coracoideus, are a tiny species belonging to the genus Bunocephalus and are a member of the Bunocephalinae subfamily. It is also known as a bicolor banjo catfish, banjo pleco, guitarrita, or dysichthys bicolor. They are found in different parts of South America such as Peru, the Amazon River in Bolivia, Uruguay, Brazil, and Ecuador.
They are small scaleless catfish with a wide head and slender body that resembles a banjo and a long tail.
Due to the extremely tiny size of the organs like their eyes and mouth, it is not possible to properly locate them. They have distinct pectoral fins but the adipose fins are absent, like most catfish they also lack the locking mechanism on their dorsal spines.
They prefer feeding on live foods like bloodworms and earthworms, but also don't mind eating frozen or flaky foods if they reach the bottom of the water tank.
This fish can survive in both flowing waters and stagnant waters. If they are kept in the aquarium the size of the tank should be 25 gallons with temperature ranging from 68-84 F. They adjust with most of the small species in the tank, they are usually bottom dwellers and like to stay alone.
They produce eggs at night in the darkness and incubate the eggs, unlike most fish. The eggs hatch in days and the fry come out.

These banjo catfish incubate their eggs.
