Description
The Nicaraguan Cichlid (Hypsophrys nicaraguensis), also known as the Nicaraguense Cichlid or Macaw Cichlid, is a beautifully coloured and relatively peaceful Central American species. Native to the rivers and lakes of Nicaragua and Costa Rica, this cichlid stands out for its shimmering gold, blue, and turquoise body and its compatibility with a wide range of tank mates. Ideal for aquarists seeking a colourful, manageable alternative to more aggressive New World cichlids, the Nicaraguan Cichlid is both hardy and rewarding to keep.
