carnegiella-marthae

An attractively marked small growing species, the Blackwing or Marthae Hatchet is primarily found in slow moving shallow waters in the Peruvian Amazon. In the wild, they tend to inhabit clear, warm, slightly acidic water and unlike other hatchet species spend much of their time below the surface mid water column. A social, schooling fish, they will do best in groups of 5 (ideally 8-10) or more in the aquarium and require excellent water quality and peaceful tankmates.
