Lebiasinid

Lebiasinid is a family of small, freshwater fish that belong to the order Characiformes. They are native to Central and South America, particularly in the tropical regions of countries such as Costa Rica, Panama, and Ecuador. These fish are characterized by their small size, typically measuring between 2-6 centimeters in length, and slender bodies.

The Lebiasinid family is diverse and comprises 34 genera, with over 300 species. They are found in a variety of aquatic environments, including rivers, streams, and lake habitats. These fish are generally opportunistic feeders, preying on small invertebrates, crustaceans, and plankton.

Some species within the Lebiasinid family are known for their vibrant coloration and complex social behaviors. They are often kept as aquatic pets in small, closed systems, where they require stable water parameters and proper nutrition. Some popular species among aquarium hobbyists include the Pygmy corydoras, Aphyocharacidium andersoni, and Copeina guttata.

In the wild, Lebiasinids play an important role in their ecosystems as both predators and prey. They are also often targeted by commercial fishers due to their small size and high reproductive rates.

However, the Lebiasinid family is also vulnerable to habitat destruction and overfishing. Their small size and relatively low commercial value make them an understudied group in terms of ecology and conservation. Nevertheless, research on this family has highlighted the importance of preserving their habitats and reducing the impacts of human activities on these ecosystems.
