This Angel is named for its collection locality, the middle Rio Nanay in Peru, a tributary of the middle Amazon. One of the characteristics that distinguishes this naturally occurring form of angel is its vivid reddish or pink spots which become more prominent with age. In the wild the Rio Nanay Angel is found in warm, acidic, heavily tannin-stained waters close to fallen branches or submerged driftwood piles. In the aquarium, they will do best when kept under similar conditions, ideally in a group of at least 5 fish and with plenty of cover. Like all freshwater angelfish, they are peaceful for a cichlid and will coexist with a wide range of tankmates provided they are not overly aggressive or small enough to become a meal.
