Headstander
A headstander is any of several species of South American fish, including ''Anostomus ternetzi'', ''Anostomus anostomus'' (family Anostomidae) and members of genus ''Chilodus'' from the family Chilodontidae. The name derives from their habit of swimming at a 45° angle, head pointed downwards, as if "standing on their heads". About The headstander is a fairly large fish. They are predominantly found in shallow streams with strong currents and a lot of algae, which they feed off of. They come from South America South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the southe ... and prefer slightly acidic water with medium hardness. The headstander will eat almost any kind of food, but mostly enjoy hair algae.

Anostomidae
The Anostomidae are a family of ray-finned fishes that belong to the order Characiformes. Closely related to the Chilodontidae and formerly included with them, the Anostomidae contain about 150 described species. Commonly known as anostomids, they are found in freshwater habitats from the Río Atrato in northernmost South America to warm-temperate central Argentina; they are of Amazon origin, with few found west of the Andes (mainly in Colombia and Venezuela). Their scientific name approximately means "mouth on top", from Ancient Greek ''áno-'' (ἄνω) "up" (as an adverb) + ''stóma'' (στόμᾶ) "mouth", in reference to the arrangement of these fishes' mouth opening.FishBase (2004), Sidlauskas & Vari (2008) Description Anostomids have elongated bodies ranging from in length; their shape varies between fusiform and deeper-bodied, but even the latter are only moderately laterally. They have elongated, tapering heads with rather long, straight snouts, and small apical to up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chilodontidae (fishes)
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. Chilodontids have colourful markings, making them popular in aquariums. They are small fish, all less than in adult length, and are distinguished by their habitual head-down postures. Genera This family currently contains two genera: * Genus ''Caenotropus'' (4 species) * Genus ''Chilodus ''Chilodus'' is a genus of chilodontid headstanders from South America, found in the Orinoco and Amazon Basins, as well as various rivers in the Guianas.

Fish Of South America
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most f ...
