Paretroplus lamenabe is a species of cichlid from the lower part of the Mahajamba River[1] and Lake Tseny[2] in northwestern Madagascar. Until its official scientific description in 2008, it was popularly known as the "Giant Lamena". As suggested by this name, it is a relatively large Paretroplus of the lamena group, reaching almost 20cm (10inches) in length.[1] This relatively elongate Paretroplus is closely related to the smaller P. nourissati and P. tsimoly.[1]
