Geophagus altifrons

Description

Geographic Range: Endemic to many tributary drainages of the middle-to-lower Amazon Basin including Paru, Xingu, Tapajós, Trombetas, Madeira, Negro and Purus. Originally described from the Rio Negro in Brazil.
Diet: G. altifrons is omnivorous by nature. In the wild, they sift through the substrate searching for small invertebrates and plant matter. In the aquarium, they will readily accept most high quality, fine grade prepared foods, such as spirulina flakes or small sinking pellets. For the best quality and condition, frozen foods such as brine shrimp, spirulina brine shrimp, tubifex worms, bloodworms, and daphnia should be offered regularly as well. Ideally, this fish should be offered multiple, smaller meals throughout the day rather than a single large feeding.
