Flag Cichlid: Everything You Need to Know

Flag Cichlid

The Flag Cichlid (Mesonauta festivus) is a fish native to river basins in Brazil, Peru, Paraguay, and Bolivia. It can grow up to 4.8 inches long and is sometimes kept in aquariums.

Until 1991, Flag Cichlid was thought to be the only species in its genus, but further study revealed six total species. Because of this, many aquarium Flag Cichlids are mislabeled as M. festivus instead of their true species, like M. guyanae, M. insignis, or M. mirificus.

Flag Cichlids have a more southern range compared to other species in their genus. They’ve been found near sandy shores with vegetation and muddy bottoms or shallow waters with lots of plants.

In one instance, they were found in a clear pool without vegetation; at another time, they were discovered in a small stream near a cattle pool.
