hemiod

Hemiod is a genus of freshwater fish belonging to the family Hemiodontidae. These fish are native to the Amazon and Paraguay river basins in South America. The genus contains several species, with common examples including Hemiodus unimaculatus and Hemiodus gracilis.

Hemiods are generally small to medium-sized fish, typically reaching lengths of around 10-20 centimeters, although some species can grow larger. They are characterized by their slender, elongated bodies and forked tails. Their coloration varies, often featuring silvery or bronze bodies with distinct markings such as spots or stripes. Some species exhibit iridescent scales.

These fish are primarily omnivorous, feeding on a diet that includes algae, plant matter, small invertebrates, and detritus. They are often found in schools, inhabiting various aquatic environments within their native range, including rivers, streams, and flooded forests. Hemiods are known for their peaceful disposition, making them popular among aquarists. In their natural habitat, they play a role in the ecosystem as both consumers and prey.
