Relevant Information:

Body colour black or dark brown with whitish spots. Known to scientists from only a few specimens. According to Boni fishermen in Guiana, this fish lives in the deep and rocky zones of the main riverbed. Despite its size, it is not consumed as food by native populations since it has a reputation for being dirty and sticky. Aquarium care: Would need a large tank as they grow big and are territorial. Diet: As with all of this genera they are carnivores and would need to be fed on frozen foods such as Artemia, mosquito larvae, mysis and shrimp. They can also be fed pellet and tablet foods.
