Nannostomus limatus

Nannostomus limatus, commonly known as the elegant pencilfish, is a freshwater species of fish belonging to the Lebiasinidae family of characins. They were first described in 1978 by Stanley H. Weitzman along with two other new species (Nannostomus britskii and Nannostomus nitidus), from a collection of specimens preserved in the São Paulo museum. They have been recorded from the Amazonian region of Brazil, specifically near Santarém.
