Well yes and no. Manacapuru is a town in the state of Amazonas in the country of Brazil. The Rio manacapuru and lago manacapuru are the places around where these fish originate and take one of their common names. They are also called red shoulder or red back angelfish, they are a race of P. scalare which is the species. Wild caught specimens would be considered "P. Scalare, Manacapuru" and typically display the red back to varying degrees normally associated with the fish from this region. Once they are tank breed they should technically no longer be considered "manacapuru" but instead red shoulder or red back angelfish since they are not from but rather descendant from fish collected in the area around Manacapuru in Brazil. So yes and no, I hope I explained that clearly.
