Description

The swordtail characin is a small characin from fresh water of northern South America, in Colombia, Venezuela and Trinidad. The species grows to about 5 cm and has a slender, silvery body. Remarkably, the male bears a long, paddle-tipped stalk on the gill cover that he waves like a 'flag' before the female during courtship. It schools in clear streams and feeds on insects, small zooplankton and algae. The fish is popular in the aquarium hobby. The IUCN has not evaluated the species.
