# Semaprochilodus insignis

The kissing prochilodus or flag-tailed prochilodus (Semaprochilodus insignis) is a species of South American freshwater fish in the family Prochilodontidae. It is native to central and western parts of the Amazon basin. It is migratory, moving in large groups into whitewater rivers to spawn, afterwards returning to blackwater and clearwater rivers, as well as flooded forests. It is important in fisheries and sometimes seen in the aquarium trade, but require a relatively large tank. It can reach a maximum standard length of 27.5 cm (10.8 in) and weight of 560 g (1.23 lb). It resembles the other members of the genus Semaprochilodus, where most species are silvery with orange-red fins and a striped tail. Adult S. insignis lack the dark flank spots that can be seen in adult S. taeniurus, but both species have these spots as juveniles.
