Common Name
Manacapuru Red Back Angel
Origin and Habitat
The Manacapuru Red Back is associated with the municipality of Manacapuru in Amazonas, Brazil. The town sits on the left bank of the Solimões near the confluence where the Rio Negro meets the Solimões and the great Amazon begins. Local waters include the Manacapuru River and the Lago Grande de Manacapuru lake system, plus a web of flood channels, side creeks called igarapés, and seasonally flooded forest.
During the rainy season the surrounding forest floods and leaf litter stains connected lakes and backwaters a tea color, creating clear, very soft, acidic blackwater conditions in many pockets, while nearby Solimões channels carry slower, turbid whitewater. Angels use calm margins, drowned roots, and submerged vegetation for shelter and feeding.

The Manacapuru Red Back Angel is a striking fish with vibrant red fins. It adapts well to a blackwater setup and is active but not aggressive. I added it to a 55-gallon tank with java fern and driftwood. It’s peaceful and enjoys the surface activity. Easy to care for once the water parameters are stable.

Beautiful fish with a unique coloration. I kept it in a planted tank with soft water and low pH. It does best in a well-maintained environment with plenty of hiding spots. Needs consistent water testing to maintain acidic conditions.

This angelfish is a highlight in my aquarium. It swims gracefully and stays active throughout the day. I’ve maintained blackwater conditions using peat and driftwood. The fish is hardy and responds well to regular water changes.
