Guianacara is a small genus of cichlid fish endemic to freshwater habitats in the Guiana Shield in South America.[1][2] They mostly live in moderately flowing clear- or blackwater rivers and streams, but also occur in lagoons that are seasonally flooded.[2][3][4] They are typically found over bottoms consisting of sandy patches intermixed with large rocks.[2][4]
The different species all have a dark line through the eye (its strength varies), but the adults can be separated by the appearance of the dark bar or spot on the mid-body.[3] They reach up to 12 cm (4.7 in) in standard length.[5] They mainly feed on small invertebrates.[2]
The seven recognized species in this genus are:[5]
