Description
Nannostomus eques, commonly known as the brown tailed pencilfish, is a freshwater species of fish belonging to the characin family Lebiasinidae. It occurs quite widely in South America, having been recorded in Brazil, Peru, Colombia, and Guyana. It is fairly typical of members of this genus being a small, elongated fish with prominent horizontal stripes. It is also quite commonly met with in the aquarium trade where its habit of swimming and posturing at a ‘snout-up’ angle—one of two Nannostomus species to do so, the other being Nannostomus unifasciatus—makes it a popular choice.
