Description
The Barred pencilfish is a pencilfish (Lebiasinidae) from fresh water of the Guianas in northern South America. The species grows to about 4 cm and has a very slender, elongate, cigar-shaped body, often with one or more dark longitudinal stripes. Unlike most pencilfishes the body bears a row of short dark crossbars.

The fish is harmless to humans and is popular in the aquarium trade.
