curimatids

Curimatids are a family of freshwater fish belonging to the order Characiformes. This family, Curimatidae, is native to South America and Central America. They are commonly found in rivers and streams, often in sandy or muddy substrates. Curimatids are a diverse group, with many species exhibiting a wide range of sizes and appearances.

A defining characteristic of many curimatids is their specialized mouthparts, which are adapted for scraping algae and other organic matter from surfaces. Their diets primarily consist of detritus, algae, and small invertebrates. They are generally small to medium-sized fish, with most species not exceeding 20 centimeters in length. Some species are important in local fisheries and as aquarium fish.

The family Curimatidae is divided into several genera, including Curimata, Curimatopsis, Cyphocharax, and Stegoricryptus. Recent taxonomic studies have led to revisions within the family, and the exact number of species and genera can vary depending on the classification system used. They play a role in their ecosystems as detritivores, contributing to nutrient cycling.
