Nannostomus limatus
Nannostomus limatus, commonly known as the elegant pencilfish, is a freshwater species of fish belonging to the characin family Lebiasinidae.
This fish was first described in 1978 by Stanley H. Weitzman, along with two other new species, from a collection of specimens preserved in the São Paulo museum. Only rarely imported and kept by aquarists, they have been recorded from the Amazonian region of Brazil, specifically near Santarém.
