Bunocephalus coracoideus, the guitarrito, is a species of banjo catfish found in the Amazon River basin. It occurs in Bolivia, Brazil, Peru and Uruguay where it is found in ponds and creeks that contain a large quantity of plant debris. Its diet varies, and may include organic debris from the bottom.
The species is quite popular in the aquarium trade. Both male and female reach a length of 12cm (05inches). They are generally very peaceful, however it is a predatory to small fish, such as young fry.
This fish is largely nocturnal. It is a bottom-feeder, consuming debris and smaller fish. The guitarrito lays up to 4,000 eggs into sandy substrate.[1]
