Lugubria johanna

Lugubria johanna is a freshwater cichlid fish native to South America, first described by Heckel in 1840. FishBase records it as widespread in the Amazon River basin in Peru, Brazil and Bolivia, in the Orinoco basin in Colombia and Venezuela, in the Essequibo drainage in Guyana, and in the Oyapock and Approuague drainages in French Guiana and Amapa, Brazil. It is a benthopelagic tropical fish that lives in water of about 23 to 26 degrees Celsius. The species reaches a maximum length of about 28 centimetres, which makes it a large cichlid. Its species name is based on a local name for the fish in Mato Grosso, Brazil, given as johanna guensa. FishBase notes that the species was redescribed from Peruvian material by Kullander in 1986. The IUCN Red List assessed it as Least Concern in 2020, and FishBase lists it as of no interest to fisheries.
