The Chilodontidae, or headstanders, are a small family of freshwater characiform fishes found in northern and central South America. This family is closely related to the family Anostomidae and is sometimes treated as a subfamily, Chilodontinae, within Anostomidae. Due to issues of homonymy with two other family-rank names called "Chilodontidae", it has been proposed that the fish family retain the spelling, and the other families will be either suppressed or renamed.[1]
Chilodontids have colourful markings, making them popular in aquariums. They are small fish, all less than 7 cm (2.8 in) in adult length, and are distinguished by their habitual head-down postures.[2]
Genera
This family currently contains two genera:[3]
Genus Caenotropus (4 species)
Genus Chilodus (4 species)
