The cichlids (Cichlidae) of the genus Aequidens ( Latin : aequus = "equal", dens = "tooth") live in northern and central South America to northern Argentina .
features
They are small and medium-sized cichlids with a rounded head profile. As the smallest species, Aequidens hoehnei is only 7.5 centimeters tall, while the species from the relational group of the green-gloss cichlid ( Aequidens tetramerus ) can reach a length of 25 centimeters. The base of the dorsal and anal fin are scaly in Aequidens , in contrast to Cichlasoma where the base is provided with scales.
species
Aequidens was originally a collective genus to which over 25 species were counted. After the establishment of new genera ( Bujurquina , Cleithracara , Guianacara , Krobia , Laetacara and Tahuantinsuyoa ) for species formerly assigned to Aequidens , 17 species are currently classified in the Aequidens genus . There are also some previously undescribed species.
