The Redback Amapa Angelfish (Pterophyllum scalare) is an uncommon geographic variant of the classic angelfish. It is distinctive by the red-orange coloration that it develops from its forehead to its dorsal fin. This shoaling cichlid is relatively peaceful compared to other members of the cichlid family. It also has a very thin, tall body unlike most other cichlids. The Red Shoulder Manacapuru is indigenous to Amapa, Brazil.
The Redback Amapa Angelfish will thrive in a heavily planted aquarium with driftwood and/or rock formations and gentle water flow. It is not overly reclusive, but this fish strongly prefers the cover of plants and, due to its body shape, is not likely to seek refuge in rock caves and similar structures. The Redback Amapa Angelfish is generally compatible with other peaceful fish as long as it has plenty of space. Territoriality is typically at its peak during spawning. Dwarf shrimp and other small, delicate invertebrates should not be kept with the Redback Amapa Angelfish, but more durable, larger shrimp and snails could possibly make good tankmates in a large enough aquarium. If spawning is desired, tankmates of other species should be kept to a minimum or avoided altogether unless the aquarium is very spacious.
Feeding is simple for the unfussy Redback Amapa Angelfish. High-quality dry, frozen, and live foods will all be readily accepted. Quality and variety are the keys to a diet that will ensure that this fish maintains optimal health and coloration.
